ROAD SURFACE EFFECTS ON BRAKING AND STEERING

An extensive research project has resulted in promising technological improvements to the road surface (Delugrip), as demonstrated in 58 experimental roads. In Delugrip, a dense composite of several layers of different sized asggregates, with controlled particle size, controlled voids and predetermined texture depth has been achieved to give excellent bulk water drainage despite a high actual contact area. The surface also reduces traffic spray very considerably and is beneficial in retarding the onset of surface icing. Factors such as wet grip, bulk water drainage, microstructure and traffic polishing tire wear and noise, and skid resistance are other factors also discussed. Delugrip, which is essentially a road surface of high friction dense asphalts, possesses excellent skid resistance ranging from 68 to 84 with surfaces aged from one month to 3 years old.
