GAP-GRADED VS CONTINUOUSLY-GRADED AIR-ENTRAINED CONCRETE FOR HIGHWAY FACILITIES

A SUMMARY REPORT IS PRESENTED OF A COMPREHENSIVE RESEARCH PROJECT TO INVESTIGATE THE VARIOUS PHYSICAL AND MECHANICAL PROPERTIES OF GAP-GRADED CONCRETE VERSUS CONTINUOUSLY-GRADED CONCRETE. THE PRIMARY OBJECTIVES OF THE STUDY WERE TO DETERMINE THE OPTIMUM PROPORTIONING OF GAP-GRADED AIR-ENTRAINED CONCRETE WHICH IS PRACTICAL FROM THE VIEW-POINTS OF WORKABILITY AND FINISHABILITY, TO COMPARE THE FINISHABILITY OF GAP-GRADED VERSUS CONTINUOUSLY-GRADED CONCRETE, AND TO DETERMINE SUCH PROPERTIES AS COMPRESSIVE STRENGTH, ELASTIC MODULUS, SHRINKAGE, AND CREEP. /FHWA/
