| 摘 要： | 随着交通荷载不断增加，沥青路面中面层已经成为主要承载结构层，同时也是出现车辙比较严重的结构层。依托武黄大修改造工程，对其中面层的材料组成与结构设计进行了研究。通过在中面层中就使用改性沥青，设计出抵抗车辙作用更有效的AC-20I型与AC-20S型沥青中面层结构。结果表明，通过选用出色的级配类型以及在中面层的设计中就选用改性沥青，加铺层整体抵抗车辙的能力得到加强，产生车辙的时间延长随之带来的破坏程度也减小。 |

| Abstract: | By sharp increase of traffic volume,some evidences show that the middle layer of asphalt pavement has already become the main bearing structual layer and more easy to be demonlished by rutting.This paper based on Wuhuang Highway Heavy repairing Project,and designed and researched the material combination and structure of that layer.By using modified asphalt in the middle layer,we designed the AC 20I and AC 20S structual layer which has more efficient to rutting.The result from tests showed that by using excellent gradation and modified asphalt,the capacity of resistance of rut of asphalt overlay became more powerful,the time when rut appeared would be delayed and the extent of demonlishment of rut would decrease. |
| Keywords: | asphalt overlay middle layer material combination and design mix proportation |
