INFLUENCE OF GEOLOGICAL FACTORS ON ABRASION AND SOUNDNESS CHARACTERISTICS OF AGGREGATES

A study has been made of the abrasion and soundness characteristics of crushed-rock aggregates obtained from A wide variety of igneous rocks of volcanic and plutonic origins, that range from acidic to basic in composition. The grain size and the volume of pore spaces were found to be significant geological factors controlling the evaluation of these two parameters. Fine-grained rocks when compared with coarse-grained rocks having the same porosity were found to be more sound and more resistant to wear. Mention is made of worrk carried out at the Transport and Road Research Laboratory, Crowthorne, Berkshire. (TRRL) of the effect of the energy crises on cars.
