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.

    New developments in low temperature asphalt offer both cost and environmental benefits - Dr Nizar Ghazireh (Lafarge Tarmac) & Dennis Day (Nynas Bitumen) Low temperature asphalt (LTA) technology has considerable potential for reducing carbon emissions associated with road construction. The lower temperatures used to manufacture these materials mean that less energy is required and therefore lower emissions, which create better working conditions and result in lower impact on the environment.
