EXPERIMENTAL LIME STABILIZATION IN NEBRASKA

A SUMMARY AND ANALYSIS ARE PRESENTED OF POST CONSTRUCTION OBSERVATIONS OF AN EXPERIMENTAL PROJECT FEATURING LIME STABILIZATION OF PLASTIC SUBGRADE SOILS AND UPGRADING OF INFERIOR BASE COURSE MATERIALS BY LIME TREATMENT. THREE SECTIONS FEATURED SUBGRADE STABILIZATION BY 3, 6 AND 10 PERCENT LIME AND THREE OTHER SECTIONS FEATURED BASE COURSE STABILIZATION BY 2, 4 AND 7 PERCENT LIME. PERFORMANCE WAS EVALUATED BY BENKELMAN BEAM DEFLECTION MEASUREMENTS, RUT DEPTH MEASUREMENTS, CRACK SURVEYS AND UNCONFINED COMPRESSIVE STRENGTH OF CORES. THE AUTHORS CONCLUDE THAT LIME IS SATISFACTORY FOR STABILIZATION OF PLASTIC SUBGRADES, BUT THAT IN SOME CASES AS MUCH AS 10 PERCENT LIME MIGHT BE REQUIRED. RATES OF 4 TO 7 PERCENT ARE ALSO SATISFACTORY FOR UPGRADING SUBSTANDARD BASE MATERIAL. /BPR/
