THE CASE FOR SKEWED JOINTS

THE USE OF SKEWED JOINTS IN CONCRETE PAVEMENTS IN CALIFORNIA DATES BACK TO 1932, WHEN AN EXPERIMENTAL INSTALLATION WAS BUILT ON U.S. 40 SOUTHWEST OF SACRAMENTO. NO FURTHER INSTALLATIONS WERE MADE UNTIL 1951. INFLUENCED AT LEAST IN PART BY THE SATISFACTORY PERFORMANCE OF THE 1932 INSTALLATIONS, SKEWED JOINTS HAVE SINCE BEEN USED ON PORTIONS OF AT LEAST EIGHT PROJECTS. IN THESE, VARIOUS JOINT SPACINGS AND ANGLES OF SKEW WERE USED AND THEIR PERFORMANCE OBSERVED. THE RESULTS OF THESE STUDIES INDICATED THAT: (1) WHEN MEASURED BY THE NUMBER AND MAGNITUDE OF FAULTED JOINTS THERE WAS A DECIDED ADVANTAGE IN FAVOR OF THE SKEWED JOINTS, (2) THE JOINTS SPACED AT 15 FT AND 20 FT SHOWED A MARKED SUPERIORITY OVER JOINTS SPACED AT LARGER INTERVALS, AND (3) AFTER STUDY OF HEAVY TRUCK SPECIFICATIONS FOR AXLE AND WHEEL SPACING, A SKEW OF 2 FT IN A 12-FT SLAB WITH THE OBTUSE ANGLE AT THE OUTSIDE EDGE OF THE FORWARD SLAB WAS ADOPTED. A DESCRIPTION OF VARIOUS PROJECTS AND A SUMMARY OF PERFORMANCE OF VARIOUS JOINT SPACINGS IS INCLUDED. /AUTHOR/
