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.

    Airport runway, taxiway and parking areas make high demands on paving requirements, both with concrete and asphalt techniques. Mike Woof reports. High quality surface finishes are required in airport environments for runways, taxiways and aircraft parking areas. Because of the speed at which aircraft take off and land and the massive forces exerted due to the weight of the aircraft, particularly during landing, runway structures need to be incredibly strong. The surfaces also have to be constructed to very

    Innovative developments are pushing forward concrete road construction techniques. The concrete road sector looks to benefit from some key innovations and developments now coming to market or being employed in different territories. Irregular weather and environmental conditions can alter the rate at which concrete cures, with a risk of plastic shrinkage cracks that can compromise the integrity of a pavement. Contractors cannot control the environmental conditions of a paving project and when weather patter
