Abstract

The understanding of factors associated with skidding can help the formulation of appropriate strategies for the safety and comfort of passengers, and for reducing wear and tear on moving vehicles. Pavement skid resistance is affected by: vehicle factors, related to tyre and speed; climatic factors, related to wet and dry road conditions; and road factors, including surface macrotexture and the microtexture and polishing characteristics of exposed aggregates. Accident studies have classified factors causing skidding under driving conditions, tyre properties, interaction events, and pavement roughness. Different organisations have set various standards for the minimum requirements for skid resistance and for polished stone values. Methods for measuring skid resistance include: (1) measuring the stopping distance and deceleration of stopping vehicles; (2) braking trailer-towed vehicles or test wheels mounted on vehicles; (3) measuring the sideways force developed when a wheel, inclined to the vehicle's direction of travel, is made to sideslip; and (4) portable and laboratory instruments. Dynamic vehicle-pavement interaction is discussed, together with considerations for developing anti-skid pavement surfaces, and corrective measures to be applied at skid-prone pavement locations.
