BITUMEN IN DRY LEAN CONCRETE

DETAILS ARE PRESENTED OF A LABORATORY INVESTIGATION OF THE EFFECT OF INCORPORATING BITUMEN IN DRY LEAN CONCRETE MIXES WHICH WAS UNDERTAKEN AS PART OF A STUDY OF THE INCIDENCE OF CRACKS IN ROAD BASES CONSTRUCTED USING DRY LEAN CONCRETE. THE RESULTS OBTAINED SUGGEST THAT REPLACING EITHER 10% OR 20% OF THE MIXING WATER WITH BITUMEN EMULSION IS UNLIKELY TO CHANGE SIGNIFICANTLY CRACK SUSCEPTIBILITY BUT, WHEN BITUMEN IS CONCENTRATED AS A PRECOATING AROUND THE COARSE AGGREGATE PARTICLES, THERE IS A SUBSTANTIAL REDUCTION IN COMPRESSIVE STRENGTH, IN TENSILE STRENGTH AND IN MODULUS OF ELASTICITY. /AUTHOR/
