PLASTICS TO PUSH OUT STONE AND CONCRETE?
WORK AT THE MILITARY ENGINEERING EXPERIMENTAL ESTABLISHMNET, AIMED INITIALLY AT PRODUCING QUICK, LOW-COST RUNWAYS, POINTS THE WAY TO THE USE OF PLASTIC FOAMS AS STRUCTURAL MATERIALS. POLYURETHANE FOAM HAS SUCH A WIDE VARIETY OF ATTRIBUTES THAT SCIENTISTS ARE ENGAGED IN A SERIES OF INVESTIGATIONS WHICH ARE DESIGNED TO EXTEND THE CURRENT PRODUCT RANGE FOR INSULATION AND BUOYANCY PURPOSES TO ENCOMPASS STRUCTURAL APPLICATIONS IN HOUSING, ROADS AND AIRFIELDS. CURRENT PAVEMENT STANDARDS FOR SKID RESISTANCE CAN BE ACHIEVED BY SPREADING SAND WITH APPLICATION RATES AS LOW AS 3 OZ/YD SQUARED ONTO THE UPPER SURFACE WHILE IT IS STILL TACKY. PRELIMINARY TESTS INDICATE THE FEASIBILITY OF POLYURETHANE PAVEMENT PRODUCTION WITH LARGE MOBILE PLANT. THE COST OF PAVEMENT LAYING WITH A PRODUCTION MACHINE IS ESTIMATED TO BE COMPETITIVE WITH EXPEDIENT SURFACING CURRENTLY USED FOR BOTH CIVIL AND MILITARY OPERATIONS.
