EPOXY-ASPHALT OPEN-GRADED PAVEMENT AS A SKID-RESISTANCE TREATMENT ON THE SAN FRANCISCO BAY BRIDGE

IN LATE 1969, THE DIVISION OF BAY TOLL CROSSING APPLIED 1/2-IN. THICK EPOXY ASPHALT, OPEN-GRADED PAVEMENT TO 2 LARGE TEST AREAS ON THE HEAVILY TRAVELED SAN FRANCISCO-OAKLAND BAY BRIDGE. TWO TYPES OF AGGREGATE, AIR-COOLED IRON SLAG AND GRANITE, WERE USED WITH 1/4-IN. CALIFORNIA STANDARD OPEN GRADING. THIS REPORT DESCRIBES THE SELECTION OF EPOXY ASPHALT AS THE SKID-RESISTANT TREATMENT, ITS APPLICATION, AND ITS PERFORMANCE TO DATE. IN THE 11 MONTHS SINCE ITS APPLICATION, THE PAVEMENT HAS BEEN TESTED FOR SKID RESISTANCE AND CORE PULLOUT STRENGTH. IN SPITE OF MINOR LOCALIZED RAVELING ATTRIBUTED TO INADEQUATE COMPACTION IN ISOLATED AREAS DUE TO COLD TEMPERATURES AT THE TIME OF PLACING AND TO OTHER FACTORS, THE PAVEMENT PROMISES FULLFILLMENT OF THE PURPOSE FOR WHICH IT WAS SELECTED: TO PROVIDE INCREASED SKID AND HYDROPLANING RESISTANCE, LOW INCREASE IN DEAD LOADS AND SUPERIOR STRUCTURAL PROPERTIES. THE ACCIDENT HISTORY HAS IMPROVED SUBSTANTIALLY IN THE RESURFACED AREAS. /AUTHOR/
