AGGREGATE SHAPE AND SKID RESISTANCE

Natural sands and sands manufactured by crushing larger parent materials are characterized and service tested. Singular attributes are usually confounded with other variables in service tests. Dry-bulking tests and photomicrography are used to established qualities. High-stability porous mixtures are achieved in laboratory tests. Crushing some materials to coarse chip sizes leaves many smooth facets on particles that then tend to become oriented horizontally in the pavement surface. Open-graded friction courses and sprinkle treatments are included. Damage by winter freezing of porous courses is illustrated. (Author)
