NEW ROAD INDUSTRY CODE OF PRACTICE FOR GROUTED MACADAM SURFACING

A new industry Code of Practice for Grouted Macadam Surfacing has been published by the Road Surface Treatments Association (RSTA). It forwards industry best practice and has been peer reviewed and endorsed by ADEPT, the Association of Directors of Environment, Economy, Planning & Transport.

Grouted Macadam surfacing is used to re-profile and strengthen the road surface – thereby providing improved texture, skid resistance and prevention of water ingress.  It offers an alternative to standard asphalt and macadam surface courses.

There are two main types of Grouted Macadam surfacing – those grouted with an asphaltic grout and those with a cementitious grout.  Both provide impervious finishes with an extended service life.

Asphaltic Grouted Macadam consists of a hot, paver laid, open-graded asphalt, purposefully designed receiving course, laid to a depth of between 30mm and 50mm, which is then sealed with an asphaltic grout.  It provides an impervious surface course, combatting water ingress with the flexibility to withstand underlying movement.  The sealing of the surface course also prevents fretting, reduces the speed of binder oxidation and reinforces the strength and elastic stiffness of the surface course.  The material is ideally suited to the resurfacing of flexible or concrete rural and residential highways.

Cementitious Grouted Macadam consists of a hot, paver laid, open-graded asphaltic, purposefully designed receiving course, typically laid to a nominal depth of between 35mm and 50mm with a controlled void content which is subsequently filled with a resin cementitious grout.  This provides a hybrid between asphalt and concrete with fast installation, minimal downtime and a resulting stiffness that falls between concrete and conventional bituminous surfacing materials. It has a high heat resistance and is therefore less temperature susceptible than traditional bituminous materials. A flexible, jointless, heavy-duty surface course, it is capable of withstanding intense traffic loadings and fuel / leachate contamination to minimise rutting or deformation. This material is ideally suited to the surfacing of high-stress areas.

The new code underlines the need for careful consideration of a wide range of details, to plan and design the work carefully and to use only HAPAS (or equivalent) approved installers certificated to BS EN ISO 9001:2008 / 9001:2015 and National Highways Sector Scheme 16.  As there is no British Standard design criteria for Grouted Macadams it is important for the client to satisfy himself that the contractor has sufficient knowledge and experience, that the product is suitably established and has been adequately tested and approved to perform as expected, and that it has demonstrated the durability required to meet the necessary service life.

The health and safety, environment, training and quality assurance responsibilities of client and contractor are set out by the code. It also provides guidance on site planning, programming, co-ordination and traffic management.  A useful inclusion is the pre-contract, on-site and post-contract check-lists.

RSTA INDUSTRY CONFERENCE REPORT: THE NEW RULES

The theme of this year’s Road Surface Treatments Association (RSTA) industry conference was ‘The New Rules’. However, the conference also proved that the old problems resulting from the lack of investment in road maintenance are getting worse.

John Paterson, Atkins, opened the conference by highlighting how the rules concerning road maintenance were changing by outlining the new UK code of practice for highway authorities, ‘Well-managed highway infrastructure’, which has been published by the UK Roads Liaison Group (UKRLG). The new code supersedes three previous codes, ‘Well-maintained highways’, ‘Well-lit highways’ and ‘Management of highway structures’. These are now rationalized into one document.

The main change is the move away from the reliance on specific guidance and recommendations to a risk-based approach to be determined by each local authority following analysis of local needs, priorities and affordability. In addition, the code calls for a consistent approach based on collaboration between all authorities and alliances, both local and strategic. To back this up, authorities are encouraged to develop appropriate records and make a detailed inventory of highway assets. They are also encouraged to consider the adoption of new and emerging technologies in order to driver greater efficiency. Although not statutory, highway authorities are expected to have fully signed-up and implemented the new risk-based approach by October 2018.

And the benefits of this new approach? Paterson believes them to be strengthened and better asset management, increased efficiencies, improved accountability based on evidence, empowered highway authorities meeting local needs, and importantly, support for making the case for funding.

The need for rationalization is also behind the review and updating of the ‘Design Manual for Roads and Bridges’. First published in 1992 the manual comprises over 300 documents, over half of which are additional advice notes.

Arash Khojinian of Highways England explained that the revision of the manual will forward the drivers of safety, efficiency, environmental input and affordability – both initial and whole life cost. Importantly, the new manual will encourage innovation as it will move away from prescriptive to performance-based standards. The manual will continue to set out the requirements for the UK motorway and all-purpose trunk road network only.

Khojinian underlined the importance of this review as part of the undertaking for when in 2015 the Highways Agency became Highways England, a government-owned company. This called for the review of DMRB “to reduce the number of prescriptive standards and increase the number of performance standards, in line with industry best practice, and thereby reduce the number of departures from standards.” Importantly, the new DMRB will place responsibility for design justification with the supply chain designer. It will provide advice to support professional decision making. Above all, the new DMRB will enable Highways England to meet the challenges of balancing priorities against demands, innovation versus risk and ensuring collaboration for mutual benefit.

The timescale is tight as the manual is due to be updated by March 2020 and this includes one year when the draft will be submitted to Europe for approval.

Owen Jenkins, Oxfordshire County Council, gave the local authority response to the new rules against a background of considerable financial pressure. Increasingly, local authorities are having to balance funding the needs of the vulnerable against providing the essentials versus financing the ‘nice to haves’. The funding of social care and refuse collection means less investment in road maintenance as unfortunately rising social care costs means that a road surface in good condition is seen as a ‘nice to have’. To illustrate his point, Jenkins reported that local authority spend as a percentage of national GDP is at its lowest since 1948.

Oxfordshire has addressed the financial pressures by making cost savings of £300 million with a further £77 million to come. The County Council is concentrating on delivering simpler and better services that are more local at lower cost. Jenkins hopes that Oxfordshire, by being part of the England’s Economic Heartland initiative, will attract growth in council and business tax via a growth in new homes and businesses.

He welcomed the new guidance provided by the new ‘Well-managed highways infrastructure’, as being built on the principles that many authorities have already adopted and for providing the case for a well-managed resilient network against one that is just well-maintained. However, he warned that the new code by being rationalized and simpler should not result in any dumbing down of asset management approach. Nor should it be used as a tool for further budget cuts.

The new rules set out in the new code of practice and the new DMRB have been developed against a background of continued under investment in roads, particularly in local road maintenance. Howard Robinson of RSTA provided a range of startling statistics, many of which are the government’s own, that demonstrated the old problems of increasing traffic demands and deteriorating roads are getting worse not better.

He pointed out that despite local roads representing 98% of the total road network and carrying 67% of the country’s traffic, they receive far less investment than the strategic road network (SRN). The Local Government Association estimates that £1.1 million per mile is invested maintaining the strategic road network. This figure drops to only £27,000 per mile for the local road network. Highways England has a 5 year plan with targets for customer satisfaction and network performance. There is no such plan for highway authorities who instead face ongoing cuts in budgets, have to jump through the hoops of complex funding arrangements and have a far greater backlog of repairs to address due to decades of under-investment. Latest figures from the Asphalt Industry Alliance’s ALARM Survey put the pothole repair bill at over £12.06 billion with one in six local roads being in such a poor state that they may have to be replaced within the next five years. With the Department for Transport predicting a 12% increase in traffic by 2025 and a 43% increase by 2047 things can only get worse.

Robinson stated that road investment is now reaching a critical stage for the local road network. The government’s recognition that poorly maintained roads have negative social and economic impacts needs to be matched by a real long-term increase in funding. He called for the investment of an additional 2p per litre of the existing fuel duty to fix the plague of potholes. This would provide an additional annual £1 billion. Robinson welcomed the focus on asset management, the benefits of a risk-based approach and the need to make smarter decisions to get better value and to increase efficiencies. These drivers are the way forward. However, smart decisions and improved efficiencies can only go so far. Without significant increase in funding the new rules will be stymied by the old problem of lack of investment.

NEW SURVEY FINDS LOCAL ROAD CONDITION GOING FROM BAD TO WORSE

The 2017 Annual Local Authority Road Maintenance (ALARM) survey makes for grim reading. It reports that decades of investment in road maintenance combined with an aging road network and increased traffic levels means that within the next five years one in six of local roads will need significant repair or may even face closure due to their poor condition.

Produced by the Asphalt Industry Alliance (AIA) and based on data supplied by 63 per cent of local authorities responsible for roads in England and Wales, the survey provides a definitive overview of the poor state of the local road network. It reports that the cost to restore the local road network to a satisfactory condition would cost over £12.06 billion and that it would take 13 years to address the backlog of potholes in England and nine years in Wales.

Over the last year local highway authorities repaired 1.7 million potholes – one every 19 seconds –  however,  they are playing a never-ending catch-up game that is exacerbated by ongoing budget cuts.

“It is not just about the provision of a realistic level of investment in what is our most important infrastructure asset. But for that funding to have long-term assurance so that highway authorities can carry out cost planned, cost efficient programmes of maintenance and not expensive emergency repairs,” explained Howard Robinson, chief executive of the Road Surface Treatments Association (RSTA). “Cost-effective maintenance that prevents potholes from forming in the first place surely is the logical financial approach”.

He continued: “Without a significant increase in road maintenance investment the condition of our roads will go from bad to worse. The survey’s finding that a sixth of local roads could be unusable within five years is of considerable concern.”

CHANCELLOR FOLLOWS ROAD MAINTENANCE FAILURE OF HIS PREDECESSORS

“In his Spring Budget Philip Hammond, has failed to address the decades of under-investment in road maintenance,” said Howard Robinson, chief executive of the Road Surface Treatments Association (RSTA). “His budget has no recognition that a well- maintained and efficient local road network supports the national economy. Instead we have a local road network that is increasingly Third World.”

RSTA has renewed its support of the calls by the Local Government Association to address the decades of under-investment in the local road network by injecting a further £1 billion a year into roads maintenance. The additional funding could be found by investing just 2p per litre of the existing fuel duty without any need to increase fuel duty rates.

The Chancellor announced £690m funding competition for local authorities to tackle congestion and to get local transport networks moving. “Some highway authorities have seen a 50% reduction in their road maintenance budgets. It is a pity that they will have to spend precious resources on competing for funding,” said Robinson.

Although the Department for Transport did announce in January 2017 funding of £1.2 billion for English local roads for the period 2017-18. That does not address the staggering £12 billion necessary to address the current backlog of repairs and potholes and bring the road network up to an acceptable standard.

The £1.2 billion funding includes £210 million from the National Productivity Investment Fund as announced in the 2016 Autumn Statement, £801 million Local Highways Maintenance Funding – Needs Element, £70 million from the Pothole Action fund, £75 million from the Highways Maintenance Challenge Fund where local highway authorities have to compete for funding and a further £75 million from the Highways Maintenance Incentive Element which requires completion of a self-assessment questionnaire ‘in order to reward those who demonstrate they truly understand the value of their asset’.

“It is disappointing that the Chancellor fails to appreciate the social and economic benefits of a well-maintained local road network,” said Robinson. “We note that that from 1 April 2017 vehicle excise duty rates for cars, vans and motorcycles registered before April 2017 will increase by Retail Prices Index (RPI) while VED for HGVs and the Road User Levy rates will be frozen. We call upon the Chancellor to consider channelling the funds from the VED rate increase towards road maintenance.”

CSCS Cards with Industry Accreditation

CSCS, under the direction of the Construction Leadership Council, will be removing the Industry Accreditation “IA” (AKA Grandfather Rights) category for CSCS cards.

This route has been closed to new operatives since 2010 but those historically holding their CSCS cards with IA have been able to renew as normal.

This route will be closing and the card holder will need to achieve the appropriate qualification for their role.

There is no confirmed date for this and so for now those holding CSCS cards through IA will be able to renew, but need to be aware that this will change in the near future.

PETITION GOVERNMENT FOR MORE SPENDING ON FIXING POTHOLES

The Road Surface Treatments Association (RSTA) has set-up a parliamentary petition urging the government to invest an additional 2p per litre of the existing fuel duty to fix the plague of potholes afflicting the local road network.

The petition may be found at https://petition.parliament.uk/petitions/183637

Decades of under investment in local road maintenance has resulted in a pothole bill of £12 billion. Despite this, lack of funding means that highway authorities are having to reduce their road maintenance budgets. Investing just 2p per litre of the existing fuel duty would provide an extra £1 billion per year to address this.

“A further £1 billion annual investment would certainly help local authorities tackle the damage done by under-investment by successive governments,” argued Howard Robinson, RSTA chief executive. “We urge all drivers to sign the petition so that Parliament will have to debate the issue of our potholed, deteriorating roads.” 100,000 signatures are required before the petition can be considered by Parliament.

 

 

 

 

NATIONAL POTHOLE DAY: THE VITAL STATISTICS

As part of National Pothole Day 2017, the Road Surface Treatments Association (RSTA) has published a compendium of facts and figures behind the UK’s deteriorating local road network together with a call for action to address the sorry state of affairs.

The 2016 statistics, pulled from a wide range of sources, underline the result of decades of under-investment in maintaining the UK’s most important infrastructure asset. According to the Annual Local Authority Road Maintenance Survey it would cost £11.8 billion and take 14 years to fix the current backlog of pothole repairs. The Local Government Association reports that the government plans to invest £1.1 million per mile of motorway and trunk road which accounts for just 3% of the total road network yet will spend only £27,000 per mile on local roads despite their making up 97% of the total road network and carrying two-thirds of all traffic. Meanwhile, motoring organisation RAC states that last year 31,483 compensation claims for vehicle damage were submitted against councils and the AA reports that 39% of its members’ vehicles have suffered from pothole damage.

“The evidence is there for all to see, and for tyres and axles to be damaged despite the best efforts of councils in repairing over 2 million potholes last year. The magnitude of the task due to decades of under-investment means that the local road network continues on its downward spiral”, said Howard Robinson, RSTA chief executive.

RSTA has called for a number of actions to address this continued deterioration. This includes government realising the need for proper levels of predicted, long-term maintenance funding that should be ring-fenced for local road spending and investing an additional annual £1 billion that come from providing an additional 2p from the existing fuel duty. In addition, all local highway authorities should sign up to best practice asset management to ensure that they have the most cost-effective maintenance approach and all road users should keep up the pressure by reporting all potholes that need repair.

“National Pothole Day is about focussing attention on the poor state of our local road network. The facts and figures compiled by RSTA underline how necessary that focus is”, said Robinson

ROADS MAINTENANCE SECTOR BACKS CALLS FOR EXTRA £1 BILLION A YEAR

The Road Surface Treatments Association (RSTA) supports calls by the Local Government Association (LGA) to address the decades of under-investment in the local road network by injecting a further £1 billion a year into roads maintenance. The additional funding could be found by investing just 2p per litre of the existing fuel duty without any need to increase fuel duty rates.

LGA has made its call following analysis that shows the pothole repair bill could reach £14 billion within two years. The total amount needed to bring the country’s local road network up to a reasonable standard has been rising as the impact of under-investment is compounded by the demands of increase traffic growth. In 2012, is was estimated that £9.8 billion was needed to repair the pothole backlog. This rose to £11.8 billion in 2016. At this current rate is it predicted to rise to £14 billion by 2019.

The LGA points out that over the remaining years of the decade the Government will invest more than £1.1 million per mile in maintaining national roads – which make up just 3 per cent of all total roads. This level of investment contrasts starkly with the £27,000 per mile investment in maintaining local roads, which are controlled by councils and make up 97 per cent of England’s road network.

“The result is that routine road maintenance budgets have to be cut and the state of local roads will continue to deteriorate in comparison to the well-resourced national road network”, said Howard Robinson, RSTA chief executive.

He continued: Cash strapped local highway authorities are doing what they can and over the last year they have filled in over 2 million potholes. However, the lack of assured real long-term funding means that much of this is expensive reactive repair rather than cost-effective preventative maintenance that would have prevented the potholes from forming in the first place. This has long been the logical economic argument forwarded by the road maintenance industry. It costs only £2m2 to surface dress and maintain a road for 10 years but costs an average £57m2 to repair one pothole.

A further £1 billion annual investment would certainly help local authorities tackle the damage done by under-investment by successive governments.”

AUTUMN STATEMENT FAILS LOCAL ROAD NETWORKS – Response from the Road Surface Treatments Association

Chancellor Philip Hammond has failed to address the fundamental issue facing the UK’s transport infrastructure – there is little point in making significant investments in headline projects if the roads that connect them are potholed and crumbling away.

“Unfortunately, the Chancellor has today has shown the same lack of understanding as his predecessors. The £1.1 billion announced in today’s Autumn Statement for local transport networks will do little to address the decades of underinvestment in load road maintenance which has resulted in a £12 billion backlog of pothole repairs”, said Howard Robinson, chief executive of the Roads Surface Treatments Association (RSTA).

He continued: “The Chancellor makes much of the need to invest in infrastructure to prove that Britain is open for business. Yet over 90 per cent of our traffic is carried by a local road network that is simply not up to scratch. He has failed to understand that the local road network is the essential link to headline projects such as the Cambridge to Oxford expressway.

Investment in infrastructure may be summed up by the idiom ‘learn to walk before you run’. Invest in fundamental and essential road maintenance before you announce grand projects. Or do both.”
