POLYMER-IMPREGNATED CONCRETE FOR HIGHWAY APPLICATIONS

POLYMER-IMPREGNATED SURFACE TREATMENTS HAVE BEEN DEVELOPED TO IMPROVED DURABILITY OF BRIDGE DECKS. SEVERAL MONORMER SYSTEMS HAVE BEEN IDENTIFIED THAT, AFTER SOAKING INTO CONCRETE, CAN BE POLYMERIZED AT TEMPERATURES OF 125 DEGREE F OR HIGHER. THE STRENGTH AND STIFFNESS OF THE POLYMER-IMPREGNATED CONCRETE ARE INCREASED BY SEVERAL TIMES. SURFACE TREATMENT EVALUATIONS WERE PERFORMED TO DETERMINE THE EFFECTIVENESS OF THE TREATMENTS. FREEZE-THAW TESTS INDICATED THAT FIELD TREATED SLABS WERE MORE DURABLE THAN NON-AIR-ENTRAINED CONTROL SLABS. AIR-ENTRAINED CONTROL SLABS WERE QUITE DURABLE BUT WERE LESS RESISTANT TO SCALING THAN TREATED SLABS. TREATED SLABS RESULTED IN IMPROVED WATER TIGHTNESS IN ALL CASES. AFTER UNDERGOING FREEZE-THAW TESTS, MANY IMPREGNATED SLABS, MAINTAINED A RELATIVELY WATERTIGHT CONCRETE SURFACE. IN WEAR TRACK TESTS, 8 OF 9 POLYMER TREATMENTS PROVIDED SIGNIFICANTLY HIGHER SKID RESISTANCE TAHN CONTROL SLABS. AFTER GRIT AND WATER WERE APPLIED, THE SKID RESISTANCE OF ALL TREATED SPECIMENS DECREASED; HOWEVER, AT THE TERMINATION OF THE TEST ALL TREATED SPECIMENS HAD A SKID RESISTANCE EQUAL TO OR SLIGHTLY HIGHER THAN THE CONTROL SPECIMENS HAD. SURFACE WEAR WAS ABOUT EQUAL FOR TREATED AND UNTREATED SLABS. WEAR MEASURED BY SANDBLAST TESTS SHOWED A HIGHER ABRASION RESISTANCE FOR TREATED SLABS. TESTS ON SURFACE-TREATED REINFORCED BEAMS INDICATED A 22% HIGHER STRENGTH THAN FOR UNTREATED BEAMS. UNDER CYCLIC LOADING, NO SPALLING OF THE SURFACE HAS BEEN OBSERVED TO DATE. UNREINFORCED BEAMS BROKEN IN FLEXURE HAVE BEEN REPAIRED SUCCESSFULLY WITH MONOMER SYSTEMS THAT YIELD APPROXIMATELY THE ORIGINAL FLEXURAL STRENGTH. SIGNIFICANT SAVINGS ARE LIKELY IF THE SURFACE TREATMENT PROCEDURES ARE IMPLEMENTED. /FHWA/
