The skidding resistance of bituminous concretes: correcting for the polishing resistance by mix design

Many factors play a role in creating satisfactory skidding resistance when a road is first opened and in maintaining it under traffic. These include the longitudinal and transverse characteristics of the pavement, rapid drainage of surface water and surface texture. The principal constituent of bituminous concrete is the aggregate. This must have intrinsic properties and be manufactured such that it complies with specifications for in-service characteristics that depend on the amount of heavy vehicle traffic the pavement will carry and its configuration. The design of the bituminous concrete makes a decisive contribution to its texture and its durability as a result of: the grading and maximum particle size; the nature of the aggregate, in particular its polishing resistance; and the type and proportion of binder. This study sets out to: demonstrate that appropriate mix design may in certain cases correct for aggregate polishing resistance; identify the relative influence of grading curve and maximum aggregate particle size; and contribute to increased road safety. This is based on trials conducted on pavements with very high levels of heavy traffic whose skidding resistance was monitored over time. For the covering abstract see ITRD E157233
