THE EARLY TRAFFICKING OF BONDED CEMENT MORTAR SURFACINGS ON CONCRETE ROADS. TECHNICAL REPORT

SCALED CONCRETE ROAD SURFACES REPAIRED BY BONDED SURFACINGS OF PORTLAND CEMENT MORTAR OR CONCRETE ARE USUALLY CLOSED TO TRAFFIC FOR 3 TO 7 DAYS TO DEVELOP STRENGTH. LABORATORY AND FIELD TRIALS TO EXAMINE THE POSSIBILITY OF OPENING CEMENT MORTAR REPAIRS TO TRAFFIC WITHIN 24 HOURS ARE DEVELOPED. TESTS HAVE SHOWN THAT MORTAR SURFACINGS LESS THAN 1/2 IN. THICK DEVELOP A CUBE STRENGTH OF THE ORDER OF 4000 LBS PER SQ. IN. WITHIN 24 HOURS, CAN BE OPENED TO HEAVY COMMERICAL RUBBER-TIRED TRAFFIC. /RRL/
