dc.description.abstractAsphalt-Portland Cement Concrete Composite (APCCC) is a hot-mix asphalt with air voids in the range of 25 to 30 percent which is later filled with resin modified cement grout. The resin modified cement grout consists of portland cement, fly ash, sand, water, and prosalvia (PL7) additive. The objective of the research was primarily to evaluate the asphalt-portland cement concrete composite under laboratory conditions. Asphalt-portland cement concrete composite specimens were prepared using the Marshall procedure. The physical and durability properties of APCCC were evaluated at one, three, seven, and 28 days of curing. The evaluated physical properties include stability, indirect tensile strength, compressive strength, and resilient modulus, while the evaluated durability properties include water sensitivity, freeze-thaw and chloride intrusion resistance. Specimens were also tested for different moist curing levels to evaluate the optimum moist curing period. Three moist curing periods were evaluated: no-moist curing, one-day moist curing, and three-day moist curing. The test results were compared with those of SM-5 hot-mix asphalt (a Virginia surface mix); results of chloride intrusion resistance were compared with those of portland cement concrete specimens exposed to similar conditions. The study concluded that asphalt-portland cement concrete composite is an effective alternative technique to be used as an overlay on bridge decks especially with preformed membranes, due to its high strength, durability, and lower air void content.en
