THE USE OF FILLERISED CEMENT FOR PAVEMENT STABLIZATION COULD REPRESENT A CONSUMPTION OF APPROXIMATELY 300,000T PER ANNUM

TITRE L'UTILISATION DES CIMENTS FILLERISES DANS LA STABILISATION DES ROUTES POURBAIT REPRESENTER UNE CONSOMMATION DE PRES DE 300 000T PAR AN.

AFTER REVIEWING THE USE OF FILLERISED CEMENT IN THE STABLIZATION OF GRAVEL UTILIZED IN LOAD BASES, THE AUTHOR RECALLS THAT IN ROADBASES ONLY NON-CONTAMINATED, ADEQUATELY GRADED HARD GRAVEL OF SUITABLE ANGULARITY IS USED. TECHNIQUES REVIEWED FOR STIFFENING THE BASES OF HEAVILY TRAFFICKED ROADS ARE: STABILIZATION WITH CEMENT, GRANULATED SLAG, FAT LIME, AND BITUMEN AND THE RESPECTIVE ADVANTAGES AND DISADVANTAGES ARE DISCUSSED TOGETHER WITH THEIR INFLUENCE ON CRACKING OF THE ROADBASE AND NECESSARY THICKNESS OF THE BITUMINOUS LAYER. A DEFINITION IS GIVEN OF FILLERISED CEMENT (MIXTURE OF ROUGHLY CRUSHED CLINKER AND ACTIVE OR NON-ACTIVE FILLER). THE USE OF SUCH CEMENTS DO NOT HAVE THE DISADVANTAGES OF CONVENTIONAL GRAVEL-CEMENT WITH REGARD TO CRACKING, HOMOGENEITY OF THE MIXTURE, ETC, AND THEY ARE ECONOMICAL. FILLERISED CEMENT CAN CONSIST OF CEMENT CAN CONSIST OF CEMENT WITH AN INERT FILLER (LIMESTONE, FOR EXAMPLE) WITH APPROXIMATELY 50 PERCENT CLINKER, CEMENT WITH ACTIVE FILLER (SLAG, FLY-ASH) WITH 80 TO 90 PERCENT FILLER, AND TERNARY CEMENT CONTAINING BOTH INERT AND ACTIVE FILLERS. /TRRL/
