Title: PORTLAND CEMENT CONCRETE CONTROL TESTING IN BRITISH COLUMBIA
Abstract: EXPERIMENTS ARE DESCRIBED TO DETERMINE THE DEGREE OF QUALITY CONTROL REQUIRED ON TWO CONCRETE HIGHWAY PROJECTS. THE FIRST WAS A THREE MILE LONG, 4 LANE ACCESS ROAD (A.D.T.=3000+ PER DAY) TO THE TOP OF BURNABY MOUNTAIN (EL.1100FEET). THE SECOND WAS A THREE MILE SECTION OF A 4 LANE DIVIDED HIGHWAY AT SEA LEVEL (A.D.T.=80000). BOTH CONSISTED OF 6 INCH UNREINFORCED CONCRETE SLABS WITH SAWN JOINTS AT 15 FEET INTERVALS, LAID ON 4 TO 6 INCHES OF CEMENT STABILIZED SUBBASE. ON THE FIRST PROJECT, THE STABILIZED SUBBASE WAS IMPORTED, LOW QUALITY GRAVEL LAID ON A SILTY GRANULAR SOIL. AT THE SECOND, THE STABILIZED SUBBASE WAS NATURAL DENSE SILTY SAND KNOWN AS SURREY TILL. CONTROL TESTING WAS CARRIED OUT ON BOTH PROJECTS, THE SECOND PROJECT BEING MODIFIED, BASED ON THE RESULTS OF THE FIRST. /CGRA/
