In this work, the tire-track resistance performance of thermosetting acrylic resin polymers was studied thoroughly for the purpose of removing tire tracks and improving the colour durability of coloured asphalt pavement. The Wilhelmy plate method and sessile drop technique were applied to measure the surface energy of three types of acrylic resin emulsions as well as rubber tires. On the other hand, both physical and chemical methods were implemented to study the resistance of tire tracks and the degree of difficulty in removing the track on coloured asphalt pavement with different coatings. Through the experiments, it was found that the smaller the adhesion work between the resin emulsion and the tire residue was, the easier it was to clean the surface tire track. Furthermore, the smaller the adhesion work between the resin emulsion and the tire residue was, the less likely it was for tire marks to remain. Although spraying resin emulsion will reduce the friction resistance of the coloured asphalt pavement to a certain extent, it can still achieve the requirements of the specification. Therefore, through these analyses, the use of L4600-type resin emulsion as a coating layer is suggested to increase the colour durability of asphalt pavements as well as prevent the occurrence of ‘early failure’.

本工作对热固性丙烯酸树脂聚合物的耐胎痕性能进行了深入研究，旨在消除胎痕，提高彩色沥青路面的颜色耐久性。采用Wilhelmy板法和静滴法测量三种丙烯酸树脂乳液以及橡胶轮胎的表面能。另一方面，采用物理和化学的方法研究了不同涂层的彩色沥青路面上轮胎履带的抗力和履带的去除难度。通过实验发现，树脂乳液与轮胎残渣之间的附着功越小，越容易清理表面轮胎痕迹。此外，树脂乳液与轮胎残渣之间的粘附功越小，轮胎痕迹残留的可能性就越小。虽然喷洒树脂乳液会在一定程度上降低彩色沥青路面的摩擦阻力，但仍能达到规范的要求。因此，通过这些分析，建议使用 L4600 型树脂乳液作为涂层，以提高沥青路面的颜色耐久性并防止“早期失效”的发生。
