SHALE-ITS PLACE IN THE CONSTRUCTION OF ROAD BASES

AS THE RESULT OF A QUESTION RAISED IN PENNSYLVANIA IN 1932 CONCERNING THE USE OF SHALE IN BASES ON SECONDARY AND TERTIARY ROADS, AN INVESTIGATION WAS UNDERTAKEN BASED ON EXAMINATION OF THE SHALE SURFACED ROADS IN EXISTENCE AT THAT TIME. THIS WORK RESULTED IN THE DESIGN OF A SHALE BASE FROM WHICH THE WATER COULD DRAIN READILY AND THE DEVELOPMENT OF A TEST WHICH GIVES RESULTS COMPARABLE TO THE EFFECTS OF WEATHER AND ABRASION ON THE ROADS. BASES BUILT IN ACCORDANCE WITH THESE FINDINGS ARE IN GOOD CONDITION AFTER 4 TO 6 YEARS OF SERVICE. /AUTHOR/
