BRITISH ARENACEOUS ROCKS FOR SKID-RESISTANT ROAD SURFACINGS

Abstract

THERE IS ONLY A LIMITED NUMBER OF COMMERCIAL SOURCES OF ROADSTONE WHICH IS SUFFICIENTLY DURABLE AND RESISTANT TO POLISHING FOR USE ON PRESENT-DAY HEAVILY TRAFFICKED ROADS. THE INSTITUTE OF GEOLOGICAL SCIENCES AND THE TRANSPORT AND ROAD RESEARCH LABORATORY HAVE CARRIED OUT A SURVEY OF THE BRITISH ARENACEOUS (GRITSTONES AND SIMILAR) ROCKS WITH THE OBJECT OF FINDING NEW SOURCES OF SUITABLE ROADSTONE. AN ACCOUNT IS GIVEN OF THE SELECTION, SAMPLING AND TESTING OF A CROSS-SECTION OF POSSIBLE SUITABLE ARENACEOUS ROCKS, TOGETHER WITH A DISCUSSION OF THE RESULTS.
