近年来,日本学者对半柔性材料进行机场道面的快速修补技术进行了大量研究。该文主要介绍日本在这一方面的研究近况:通过室内试验,分析了半柔性材料的力学特性;在其基础上,大规模地铺筑试验道面,进行飞机荷载作用下的疲劳试验,以掌握半柔性道面的施工性能及路用性能;以应变为控制指标,结合有限元法和多层弹性层状理论,提出机场沥青道面加铺半柔性材料的结构设计方法。
In recent years, Japanese scholars have done a great deal of research on semi-flexible materials for rapid repair of airport pavement. This paper mainly introduces the research status of Japan in this respect: Through the laboratory test, the mechanical properties of semi-flexible materials are analyzed. On the basis of this, the test pavement is paved on a large scale and the fatigue test under aircraft load is conducted to grasp The semi-flexible pavement construction performance and road performance; the strain as the control index, combined with the finite element method and the multilayered elastic layered theory, proposes the structural design method of airport asphalt pavement plus semi-flexible material.
