Federal Highway AdministrationUS Transportation CollectionThis report describes the installation and evaluation of trial pavement patching materials in Oregon. The patches were placed in Portland cement concrete and bituminous concrete pavements and evaluated for periods ranging from four to twelve months.Of the five products used in patching the Portland cement concrete pavement, the epoxy concrete and the acrylic polymer concrete materials were found to have greater durability than the other products tested. Their costs were considered high at between $1350 to $1675 per cubic yard.The evaluation of patching materials for bituminous concrete pavements was limited to cold-mixed, cold-applied products. Of the four materials examined, Sta-Fil was rated superior. Its cost at $450/ton was a major disadvantage
