Abstract
Describes research sponsored by the Highways Agency, Quarry Products Association and the Refined Bitumen Association. Objective is to improve the performance of asphalt surfacing under the more demanding conditions than experienced at present, and may be encountered in the future. This entailed the development of a performance-based specification for the surfacing, which will offer great potential to both the Industry and the Customer. The development of the surfacing specification was carried out in three parts: The performance requirements and role of the asphalt surface layers were reviewed, A trial was carried out, using the TRL accelerated pavement test facility (PTF), to investigate the behaviour of pavement design solutions, and Trials of a draft surfacing specification developed from the TRL PTF trial were carried out under contractual conditions as part of road maintenance or road construction schemes.
