Abstract

Porus asphalt pavement, with a 20% porosity compared to conventional asphalt, allows for the generation of high-pressure water infiltration during rainfall. To prevent premature oxidation of the asphalt binder due to exposure to UV rays and wind, high-modulus asphalt binders are utilized. In addition to the standard performance grade test, a flexural beam test is conducted for freeze-thaw vulnerability assessment. Currently, flexural beam test is conducted at -20°C regardless of the performance grade. To evaluate the suitability of this test temperature, mathematical modeling and statistical analysis were performed, confirming the appropriateness of the current flexural beam test temperature of -20°C.
