SHRINKAGE COMPENSATED CEMENT IN CEMENT STABLIZED BASE COURSE

THE INTENT OF THIS STUDY WAS TO DETERMINE THE EFFECTIVENESS OF USING A SHRINKAGE COMPENSATED PORTLAND CEMENT FOR BASE STABILIZATION TO REDUCE PAVEMENT SURFACE CRACKING IN A BITUMINOUS PAVED ROAD. THE PERFORMANCE OF ROADWAY SECTIONS CONSTRUCTED USING SHRINKAGE COMPENSATED PORTLAND CEMENT IN THE UPPER FIVE INCHES OF A SOIL AGGREGATE BASE COURSE WAS COMPARED TO ROADWAY SECTIONS USING A REGULAR TYPE I OR TYPE II PORTLAND CEMENT IN A SIMILAR MANNER. THE ROADWAY SECTIONS WERE KEPT UNDER SURVEILLANCE FOR APPROXIMATELY TWO YEARS. FROM VISUAL OBSERVATIONS, THERE APPEARED TO BE NO SIGNIFICANT DIFFERENCE IN THE PERFORMANCE OF THE ROADWAY SECTIONS WITH REGARD TO SURFACE CRACKING. IT WAS CONCLUEDED THAT SHRINKAGE COMPENSATED PORTLAND CEMENT WAS NOT EFFECTIVE IN REDUCING SURFACE CRACKING WHEN USED FOR BASE STABILIZATION IN ROADS OF THE TYPE INCLUEDED IN THIS STUDY. /FHWA/
