Abstract: Technology is likely to change the way in which the asphalt industry monitors performance in two areas: (1) performance-related materials testing; and (2) non-destructive survey methods. This paper discusses some currently available test methods and some likely future changes. It concentrates on bituminous materials, both mixtures and binders. In performance-related testing of mixtures, gradual changes to end-product specifications and compliance testing are occurring. The University of Nottingham, collaborating with SWK Pavement Engineering, is continually evolving better ways of determining material properties. Whatever the test method, the production of representative specimens is important. Several new equipment types and test devices have been developed for the performance-related testing of binders. Procedures for analysing the composition of bituminous materials are likely to move from traditional solvent recovery towards an ignition method for quantitative binder determination. Performance tests may be introduced gradually to test unbound and stabilised materials. There will be more emphasis on high-speed data collection in the future at the road network level. Non-destructive survey equipment may include high-speed deflection testers, ground radar, road survey systems, and pavement friction testers. For the covering abstract, see IRRD 889137.
