SAWED CONTRACTION JOINTS FOR CONCRETE AIRFIELD PAVEMENTS

THIS CONSTRUCTION WAS CARRIED ON DURING WARM AND COLD WEATHER, AND BOTH PORTLAND CEMENT AND A BLEND OF PORTLAND CEMENT AND NATURAL CEMENT WERE USED IN THE CONCRETE MIXES. PAVEMENT THICKNESSES RANGED FROM 6 TO 12 IN. AND ALL TRANSVERSE CONTRACTION JOINTS WERE SAWED TO A DEPTH OF ONE FOURTH THE THICKNESS OF THE PAVEMENT. EXCELLENT CONTRACTION JOINTS CAN BE OBTAINED BY USING PROPERLY TRAINED WORKMEN AND EXERCISING NORMAL CARE IN CHOOSING THE TIME FOR SAWING THE JOINTS. WEATHER CONDITIONS AND CHARACTER OF THE CEMENT USED ARE IMPORTANT FACTORS IN INFLUENCING THE TIME INTERVAL BETWEEN PLACING THE CONCRETE AND CUTTING THE JOINTS. NO DIFFICULTY IS ENCOUNTERED IN FILLING THE JOINTS, EXCEPT WHEN JET-FUEL-RESISTANT FILLERS ARE USED. THESE FILLERS HAVE A NARROW TEMPERATURE RANGE THROUGH WHICH THEY MAY BE APPLIED, AND THE JOINTS HAVE TO BE FILLED IN SEVERAL STAGES TO COMPENSATE FOR SHRINKAGE OF THE MATERIAL AS IT COOLS. /AUTHOR/
