LIME RESEARCH STUDY SOUTH DAKOTA INTERSTATE ROUTES - FINAL REPORT

THE EVALUATION WAS MADE OF 16 PROJECTS FEATURING LIME STABILIZATION TO REDUCE PLASTICITY AND VOLUME CHANGE OF CLAY SOILS. THE STUDY WAS DIRECTED TOWARDS EVALUATING THE EFFECTIVENESS OF TREATMENT FOR REDUCING PAVEMENT ROUGHNESS AND MEASURING THE PERMANENCY OF TREATMENT. EFFECTIVENESS OF TREATMENT FOR REDUCING ROUGHNESS WAS MEASURED BY A HIGH SPEED ROUGHOMETER. SWELL MEASUREMENTS FROM CBR TESTS WERE MADE. MODIFIED FIELD CBR AND PLATE LOAD TESTS MEASURED THE PERMANENCY OF LIME TREATMENT. PH TESTS AND ATTERBERG LIMITS TESTS WERE ALSO PERFORMED. THE AUTHOR CONCLUDES THAT LIME TREATMENT EFFECTS A PERMANENT IMPROVEMENT WITH RESPECT TO REDUCED ROAD ROUGHNESS AND INCREASED STABILITY. LIME SLURRY DID NOT MIGRATE FROM DRILLED HOLES BUT "MAY HAVE HAD SOME INFLUENCE ON THE MOISTURE DIFFERENTIALS BENEATH THE SHALE ADJACENT TO THESE HOLES WHICH RESULTED IN AN IMPROVEMENT OF RIDEABILITY." /BPR/
