Asphalt paving innovation from Aggregate Industries

The firm developed this new surface course in a bid to match increasing traffic volumes on the UK’s road network. According to Aggregate Industries, this material can speed up road surfacing by more than 40%. There is a major need to repave many UK roads, with the country’s vehicle population having increased by 10 million in the last 10 years. This has triggered an increased need for infrastructure maintenance. But the time needed to carry out road repairs can cause major problems for motorists.

A low-temperature asphalt solution has cut paving time on a trial project in the UK

The firm developed this new surface course in a bid to match increasing traffic volumes on the UK’s road network. According to 2297 Aggregate Industries, this material can speed up road surfacing by more than 40%. There is a major need to repave many UK roads, with the country’s vehicle population having increased by 10 million in the last 10 years. This has triggered an increased need for infrastructure maintenance. But the time needed to carry out road repairs can cause major problems for motorists. The latest solution from Aggregate Industries is a low-temperature, 20mm, SuperFlex surface course that can be laid in a single layer at depths between 100mm and 130mm to achieve a minimum surface texture.

The SuperFlex surface material removes the need for two separate treatments, a binder course and surface course, delivering pavement treatment in one, saving money and time.

Aggregate Industries trialled the new SuperFlex in March 2017, resurfacing the A3 Kingston Bypass, one of the busiest roads in South London, as part of the London Highways Alliance Contract (LoHAC). The trial saw SuperFlex help reduce the time needed to complete the project by 55%.

Martin Freeman, Area Manager for the South East Contracting at Aggregate Industries said, “By using the new 20mm Superflex instead of a traditional course pavement treatment, the team delivered an astounding 43% time-saving. This allowed the contracting team to surface an average of 600tonnes/night – with an unprecedented 700tonnes surfaced on 15th March.

    By this spring, Bomag’s new BM 2200/75 cold planer will have removed all the old pavement from a 2.6km section of Germany’s federal highway B-85. Work on the section between Amberg and Pittersberg started at the end of 2016 after the Ministry of Transport classified the road as being in “urgent need” of upgrading as part of the Federal Transport Infrastructure Plan. Actual roadworks began in mid-June 2017 after essential forestry work had been carried out, such as the removal of tree roots on both sides

    A new report from the UK highlights that utilising warm mix asphalt (WMA) can help cut CO2 emissions. The All-Party Parliamentary Group on Highways has issued a report highlighting how the use of WMA can reduce carbon emissions and improve efficiencies on highways projects. WMAs are manufactured and laid at lower temperatures than traditional asphalts, using less energy and delivering carbon savings without compromising performance. Their use can reduce CO2 emissions associated with asphalt production for

    More than 3,900km of roads in England and Wales will need essential maintenance within the next year, according to the annual ALARM survey* Cash-strapped local governments are reporting that the gap between the funds they received and the amount they needed for repairs and maintenance was almost €639 million. This equated to an average shortfall of €3.75 million for every authority. It would take 14 years to get local roads back into a reasonable steady state, but only if adequate funds and resources wer
