Increasing the temperature of airport pavement softens the surface layer and causes rutting or thermal cracking. In addition, aircraft manufacturers tend to produce aircraft with heavier gross weights and higher tire pressures. The use of polymers in asphalt binders such as high-density polyethylene is an approach to mitigate these problems. This study aims to examine the properties of biopolymer-modified asphalt consisting of conventional asphalt, high-density polyethylene, and pine resin; and then compare the performance of asphalt mixtures binding conventional and biopolymer-modified asphalt binders. Physical tests, Fourier transform infrared, dynamic shear rheometer, scanning electron microscopy, energy dispersive X-ray, volumetric properties, Marshall stability, retained stability, indirect tensile strength, and Cantabro loss tests were conducted. This study showed that utilizing pine resin and high-density polyethylene increased the performance grade (PG) of conventional asphalt from PG 64 to PG 82. The stability, stiffness, and resistance to moisture damage of the mixture using biopolymer-modified asphalt were higher than those of the mixture using conventional asphalt. The properties of the mixture using biopolymer-modified asphalt fulfilled the requirements of Item P-401 documented in the Federal Aviation Administration Advisory Circular 150/5370-10H.
