Abstract:

The construction controlling elements, including construction performance at low ambient temperatures, reserved time ranges, and the strength increasing rule, for locally developed epoxy asphalt mixture(LDEAM)are studied through laboratory tests. Air void and Marshall stability are chosen as the performance measures for evaluating the construction quality. The wheel rolling test is used to simulate the actual construction situations, while the Marshall test and the Brookfield viscosity test are adopted to study the strength increasing rule. The experimental results reveal that the LDEAM can be constructed under a low ambient temperature condition of 10℃, and its longest reserved time is 70 min at a reserved temperature of 120℃. Test also shows that the strength of the LDEAM increases with time and temperature before cured. Finally, the theoretical reason for the strength increasing rule is analyzed on the basis of the organic chemistry theory.
