BITUMINOUS COURSES OR PRIMERS UNDER CONCRETE ROADWAYS

BITUMINOUS COURSES OR PRIMERS UNDER CEMENT CONCRETE SLABS ARE WATER-REPELLANT, IMMEDIATELY USABLE AND ALLOW ECONOMICAL SITE DEVELOPMENT. THEIR PROVISION ALSO SERVES TO COMPACT THE UPPERMOST LAYER (STILL LOOSE AFTER VIBRATING) OF THE SOIL OR FROST BLANKET, GRAIN SIZE SHIFT UNDER LIVE LOAD, WASHOUTS OR DAMP PATCHES IN THE SUBSOIL (WHICH ARE PARTICULARLY CRITICAL IN THE REGION OF SEAMS) ARE ELIMINATED. COMPOSITION OF THE ADDITIVES /AGGREGATE/, NATURE AND QUANTITY OF THE BINDER ARE PRECISELY CONTROLLABLE AND THE TEMPERATURE CONDITIONS UNDER CONCRETE SLABS ARE KNOWN. IT APPEARS POSSIBLE AND DESIRABLE TO USE COMPOUND MATERIALS WITH AN ELASTICITY MODULUS BETWEEN THAT OF CONCRETE /OVER 2000,000 KP/CM SQUARED/ AND THAT OF THE COMPACTED FROST BLANKET. /FG/RRL/
