IS THE ROCK ANY GOOD FOR ROAD WORK{ A SIMPLE METHOD TO ASSESS THE SUITABILITY OF ROCK FOR ROAD FOUNDATIONS

A GRADING SYSTEM DEVISED BY THE NATIONAL INSTITUTE OF ROAD RESEARCH, PRETORIA, SOUTH AFRICA, IS DESCRIBED. THE METHOD ENABLES THE DETERMINATION OF THE SUITABILITY OF ROCK IN AVAILABLE DEPOSITS FOR USE IN ROAD FOUNDATIONS, BY THE IDENTIFICATION OF THE WEATHERING CONDITION OF THE ROCK. TWO CHARTS ARE PRESENTED AS FOLLOWS' CHART 1- A GUIDE TO THE SELECTION OF IGNEOUS ROCKS, IN WHICH LUSTRE, HARDNESS AND CONSISTENCY, AND STATE OF CRYSTALLIZATION ARE DEFINED. CHART 2- SUITABILITY OF ROCK FOR ROAD BUILDING PURPOSES. THIS CHART IS BASED ON THE FACTORS DEFINED IN CHART 1. /RRL/
