USE OF BITUMEN EMULSIONS FOR IMPROVING THE HARDENING OF PAVEMENT CONCRETE /IN FRENCH/

AN ATTEMPT IS MADE IN THE USSR AT FINDING EFFECTIVE BITUMEN EMULSIONS TO PREVENT EARLY DRYING OF FRESHLY CAST CONCRETE PAVEMENT SLABS. TESTS WERE CARRIED OUT WITH EMULSIONS CONTAINING 35 TO 4 PER CENT SULFITE ALCOHOL OR OXIDIZED NAPHTA. BOTH EMULSIONS CAN BE SPREAD IN THIN LAYERS, AND FACILITATE THE SLIGHT PENETRATION OF THE BITUMEN IN THE CONCRETE THUS GIVING GOOD ADHESION BETWEEN THE EMULSION AND CONCRETE. COMPARED TO FLUXED BITUMEN, BOTH EMULSIONS ARE MORE ECONOMICAL, ESPECIALLY THE SULFITE ALCOHOL-BITUMEN EMULSION WHICH HAS LESS PORES THROUGH WHICH WATER CAN EVAPORATE. /LCPC/RRL/
