THIN POLYMER CONCRETE OVERLAY TESTED

THE FIRST MAJOR TEST STRIP OF A POLYESTER RESIN OVERLAY MATERIAL IS NOW UNDER TRAFFIC ON AN ACCESS RAMP TO TH NEW JERSEY APPROACH TO THE LINCOLN TUNNEL UNDER THE HUDSON RIVER. THE MATERIAL CAN BE SPREAD THIN, SET IN AN HOUR AND IS AS STRONG AS THE CONCRETE BELOW. IT IS RIDGID, CAN BE FORMULATED TO MATCH THE ELASTICITY AND THERMAL EXPANSION OF EXISTING CONCRETE, AND HANDLES LIKE NO-SLUMP CONCRETE. BEING MORE EXPENSIVE THAN ASPHALT OR PORTLAND CEMENT CONCRETE, IT APPEARS NOT TO BE A SUITABLE SUBSTITUTE. IT IS HOWEVER, LESS EXPENSIVE AND EASIER TO MIX AND PLACE THAN EPOXIES. ALSO, IT IS NOT SENSITIVE TO TEMPERATURE AND HAS A ROUGH SURFACE. BECAUSE AN OVERLAY IS THIN, THERE IS NO NEED TO RAISE CURBS, MANHOLES AND CATCH BASINS AND CAN BE APPLIED ON BRIDGES WITHOUT SIGNIFICANTLY RAISING DEAD LOAD.
