'WHITE ASPHALT' BEING USED FOR CONCRETE BRIDGE REPAIR

SOME 134 TONS OF 'WHITE ASPHALT' WERE RECENTLY PLACED ON 2 BRIDGE DECKS ON I-71 IN MEDINA COUNTY, OHIO. THE OHIO DEPARTMENT OF HIGHWAYS HAS BEEN USING 'WHITE ASPHALT', A SYNTHETIC BINDER, FOR SOME TIME, MAINLY FOR RESURFACING INTERSTATE BRIDGE DECKS AND LEVELING UP PAVEMENT AND APPROACH SLABS THAT HAVE SETTLED. THE PRODUCT RESEMBLES CONCRETE IN APPEARANCE BUT HANDLES LIKE ASPHALT. HOWEVER, WHEN PLACED IN THIN LAYERS, COOLING IS MUCH FASTER, AND TRAFFIC CAN PASS OVER IT ALMOST IMMEDIATELY AFTER PLACEMENT. THE SYNTHETIC BINDER, PAVEBRITE, CONTAINS A HYDROCARBON RESIN WHICH IS BASED ON A DIFFERENT CUT OF A PETROLEUM BARREL FROM THAT USED FOR ASPHALT. THE RESIN IS COMBINED WITH SPECIALLY SELECTED PIGMENTS AND OTHER INGREDIENTS TO PROVIDE A PRODUCT THAT CAN BE PROCESSED AND APPLIED IN THE SAME WAY AS ORDINARY ASPHALT. THE SYNTHETIC BINDER IS IMPERVIOUS TO WATER PENETRATION, ADDS VERY LITTLE WEIGHT TO THE EXISTING BRIDGE DECK AND IS THE SAME COLOR AS THE CONCRETE PAVEMENT. HOWEVER, IT IS CONSIDERABLY MORE EXPENSIVE THAN OTHER RESURFACE PRODUCTS. /AUTHOR/
