A REVIEW OF THE FLORIDA TEST-PIT PROGRAM

TWENTY-EIGHT FLORIDA BASE COURSE MATERIALS WERE SUBJECTED TO REPEATED PLATE LOADINGS IN A SPECIALLY BUILT TEST PIT UNDER VARIOUS DEGREES OF SATURATION WITHIN THE RANGE OF MOISTURE CONDITIONS ANTICIPATED UNDER ACTUAL ENVIRONMENTAL CONDITIONS. THE TEST PIT DEFLECTIONS WERE COMPARED TO PARAMETERS DETERMINED FROM SMALL SCALE STRENGTH TESTS. IT WAS CONCLUDED THAT TEST PIT DEFLECTIONS CAN BE CORRELATED WITH LABORATORY TESTS, INCLUDING TRIAXIAL AND LIMEROCK BEARING RATIO (LBR) TESTS. IT WAS ALSO SHOWN THAT THE STRENGTHS OF SOME LIMEROCKS ARE GREATLY REDUCED WHEN THEY ARE WETTED. DEFLECTION PERFORMANCE OF LIMEROCK BASE COURSE MATERIALS IN THE TEST PITS IS NOT RELATED TO THEIR CARBONATE CONTENT REQUIREMENTS UNDER THE CURRENT FLORIDA DOT SPECIFICATIONS. /FHWA/
