EXPANDED POLYSTYRENE AND THE IMPROVEMENT OF ROADS (FRENCH)

TO REDUCE THE COST OF ROAD CONSTRUCTION AND AVOID USING GRAVEL TO REPLACE FROST-SUSCEPTIBLE MATERIALS SUCH AS LOAM, CLAY OR MARL, RESEARCH WORKERS AT B.A.S.F. HAVE DEVELOPED ELASTIFIED STYROPOR PLATES. THESE PLATES MADE FROM PRE-FOAMED OR ELASTIFIED STYROPOR ARE LAID ON THE SUBGRADE ON LAYERS OF STONE AND ARE COVERED FIRST WITH SAND, THEN WITH SETTS, BITUMEN OR CONCRETE SURFACING. NEW TYPES OF SURFACING WITH A HEAT-RESISTANT ACRYLIC POLYETHYLENESTER- BITUMEN BASE WILL NOT SOFTEN EVEN IN EXTREME HEAT. /LCPC(A)/RRL/
