THE USE OF CRUSHED ROCK AS A STRUCTURAL PAVEMENT LAYER IN ROAD CONSTRUCTION

This report traces the development of crushed rock as a material for building roads. Its use in waterbound macadam and crushed stone bases is detailed, and the effects on performance of variables such as grading and Atterberg limits are discussed. Road experiments to evaluate different types of base material and different construction techniques are described. (TRRL)
