2001年《路面结构技术标准》引入了路面使用性能的概念，加速加载试验被认为是评价路面耐久性能的一种非常有效的方法。公共工程研究所的路面试验场被认为是日本唯一评估路面耐久性的官方试验设施。该设施提供直径200 m的圆形测试轨道，重载车辆在其上进行无人操作，由配备GPS和其他传感器的定位系统控制。为了应对全球对城市热岛效应的担忧，日本采取了各种措施来降低路面温度，包括使用能够反射太阳辐射并在路面材料中保留水分的冷路面。虽然这种路面技术理论上可以降低路面温度，但其在实际道路上的耐久性尚未得到证实。因此，本文通过对应用于日本路面试验场试验跑道的试验路面进行加速加载试验来检验其耐久性。介绍了路面试验场的概况和冷路面耐久性测试结果。
The 2001 Technical Standards for Pavement Structures introduced the concept of pavement performance, and accelerated loading tests are regarded as a very effective method for evaluating pavement durability. The Pavement Test Field at the Public Works Research Institute is acknowledged as the only official test facility for evaluating pavement durability in Japan. This facility provides a circular test track with a diameter of 200 m, on which heavily loaded vehicles are driven by unmanned operation, controlled by a positioning system equipped with GPS and other sensors. In line with global concerns over the urban heat island effect, Japan has taken various measures to decrease the road surface temperature, including the use of cool pavement that reflects solar radiation and retains water within the pavement materials. Although this pavement technique can reduce the road surface temperature in theory, its durability on actual roadways has not yet been proven. Thus, this paper examines its durability by conducting accelerated loading tests on test pavement applied to the test track on Japan's Pavement Test Field. An outline of the Pavement Test Field and the results of testing the durability of cool pavement are presented.
