AN EXPERIMENT TO INVESTIGATE ROLLED ASPHALTS WITH CRUSHED-ROCK FINE AGGREGATE: A303 MERE, WILTSHIRE

The use of crushed-rock fine aggregates in rolled-asphalt wearing-courses has produced mixtures with a good road performance but these materials can be difficult to lay and compact particularly in adverse weather conditions. To improve the workability, asphalts can be made with softer binders than the more usual 50 pen grade bitumen. This report describes the laying of 12-experimental sections of asphalt, each 100M long, made with 200, 100 and 50 pen grade bitumens with a range of binder contents, on trunk road, A303 at Mere, Wiltshire in November 1982.
