Abstract

Raising the temperature of airport pavement softens its surface, leading to rutting or thermal cracking. As aircraft manufacturers lean toward heavier planes with higher tire pressures, challenges arise. To tackle these problems, incorporating polymers like high-density polyethylene into asphalt binders has emerged as a solution. This study investigates biopolymer-modified asphalt, blending conventional asphalt with highdensity polyethylene and pine resin. This study aims to compare the performance of asphalt mixtures using both conventional and biopolymer-modified asphalt binders. Various tests‒physical, Fourier transform infrared, energy dispersive X-ray, dynamic shear rheometer, volumetric properties, Marshall stability, retained stability, indirect tensile strength and Cantabro loss-were conducted. The results highlighted that integrating pine resin and high-density polyethylene increased the performance grade (PG) of the conventional asphalt from PG 64 to PG 82. Asphalt mixtures using biopolymer-modified binders exhibited superior stability, stiffness and resistance to moisture damage compared to those with conventional asphalt. These properties aligned with the specifications outlined in Item P-401 of the Federal Aviation Administration Advisory Circular 150/5370-10H. Keywords: Pine resin, High-density polyethylene, Biopolymer-modified asphalt, Performance grade 64, Performance grade 82

用于机场路面的传统和生物聚合物改性沥青混合料性能比较

机场路面温度升高会软化路面表面，导致车辙或热裂纹。由于飞机制造商倾向于使用更重的飞机和更高的轮胎压力，挑战也随之而来。为了解决这些问题，在沥青粘结剂中加入高密度聚乙烯等聚合物已成为一种解决方案。本研究调查了生物聚合物改性沥青，将传统沥青与高密度聚乙烯和松树树脂混合。本研究旨在比较使用传统沥青粘结剂和生物聚合物改性沥青粘结剂的沥青混合料的性能。研究人员进行了各种测试，包括物理测试、傅立叶变换红外线测试、能量色散 X 射线测试、动态剪切流变仪测试、体积性能测试、马歇尔稳定性测试、保留稳定性测试、间接拉伸强度测试和坎塔布罗损失测试。结果表明，松树树脂和高密度聚乙烯的混合使传统沥青的性能等级（PG）从 PG 64 提高到 PG 82。与使用传统沥青的沥青混合料相比，使用生物聚合物改性粘结剂的沥青混合料具有更高的稳定性、刚度和抗湿损性能。这些特性符合美国联邦航空管理局咨询通告 150/5370-10H 中 P-401 项所列出的规格。关键词松树树脂高密度聚乙烯生物聚合物改性沥青性能等级 64 性能等级 82
