CORRELATION BETWEEN R-VALUE AND K-VALUE AS A BASIS FOR CONCRETE PAVEMENT DESIGN

A RELATIONSHIP BETWEEN R-VALUE AND K-VALUE FOR VARIOUS SOILS WAS ESTABLISHED, SO THAT SOIL SURVEY DATA COULD BE USED IN PORTLAND CEMENT CONCRETE PAVEMENT DESIGN. TWENTY K-VALUES WERE ESTABLISHED ON CALIFORNIA HIGHWAY CONTRACTS IN PROGRESS. TRUCK-MOUNTED PLATE BEARING TEST EQUIPMENT OF THE PORTLAND CEMENT ASSOCIATION WAS USED. SAMPLES OF THE SAME SOILS WERE TESTED TO DETERMINE R-VALUES. OTHER TESTS WERE MADE TO DEFINE SOIL TYPE AT EACH TEST LOCATION. A PRECISE CORRELATION WAS NOT FOUND TO EXIST BETWEEN R-VALUE AND K-VALUE FOR TYPICAL CALIFORNIA SOILS TESTED. A CONSERVATIVE RELATIONSHIP WAS NOTED AS USABLE IN DEVELOPING AN EMPIRICAL MODIFICATION OF PORTLAND CEMENT CONCRETE PAVEMENT DESIGN METHODS THAT USE WESTERGAARDS K-VALUE.
