| 摘 要： | 用4种不同方法计算了加铺沥青层结构的厚度,比较计算结果,并综合考虑其他因素进行加铺层结构设计。通过AAPA进行加铺沥青层反射裂缝试验研究。研究表明,所设计的加铺层结构是较为合理的,在加铺层结构中的关键层采用改性沥青是非常有必要的。

| Abstract: | Thickness of asphalt overlay was calculated by four methods in this paper.Then structure of asphalt overlay was designed by means of comparing four calculation results and considering other factors.Simultaneously experimental research on reflective cracking of asphalt overlay was carried out through AAPA(Automatic Asphalt Pavement Analyzer).Results show that the structure of asphalt overlay designed was proved rational by experimental research on AAPA.It is very necessary that modified asphalt should be adopted in critical layer of asphalt overlay structure. |
