【摘要】：上世纪九十年代中期至本世纪前五年这十年时间内,南昌市修建了大量的水泥混凝土路面城市道路。经过了十多年的运营,这些水泥混凝土路面不同程度的出现了各种病害,严重影响了道路的服务水平,降低了车辆行驶的安全性和舒适性,并导致通行能力的下降。同时水泥路面与白色的交通标线组合,区别度较低,不利于行车安全。考虑到行车舒适性、安全性以及城市景观的需要,南昌市的城市管理者们决定将城区的水泥路面逐步加铺改造成沥青路面。本文结合国内外水泥路面加铺改造的实践经验,并结合南昌市红谷滩新区红谷中大道、丰和中大道和小蓝经济开发区金沙二路共三条道路的“白改黑”改造经验,总结旧水泥路面的检测与评价指标并将其运用于实际工程中;对旧水泥路面的加铺前病害进行分类,并根据不同的分类进行针对性的处置;根据反射裂缝的成因对其进行分类,并根据旧路的病害分析结果提出不同的反射裂缝防止措施;验证了加厚沥青层对反射裂缝产生的延缓作用;分析不同加铺结构的材料与结构设计方法并将其运用于实际工程中;为日后南昌市城市道路水泥路面加铺改造设计提供一些经验和借鉴。
[Abstract]:During the decade from the mid-1990s to the first five years of this century, a large number of cement concrete pavement urban roads were built in Nanchang. After more than a decade of operation, these cement concrete pavement appeared various diseases, which seriously affected the service level of the road, reduced the safety and comfort of vehicles, and led to the decline of traffic capacity. At the same time, cement pavement and white traffic mark combination, the distinction is low, is not conducive to driving safety. Considering the need of driving comfort, safety and urban landscape, the city managers of Nanchang city decided to gradually transform the cement pavement into asphalt pavement. This paper combines the practical experience of overlay reconstruction of cement pavement at home and abroad, combined with the experience of "White to Black" transformation of three roads, Honggu Zhong Avenue, Feng he Zhong Avenue and Jinsha second Road in Honggutan New District, Nanchang City, and Jinsha second Road in Xiaolan Economic Development Zone. Summing up the detection and evaluation index of old cement pavement and applying it to practical engineering; classifying the disease before paving of old cement pavement and dealing with it according to different classification; classifying it according to the cause of reflection crack, According to the results of the disease analysis of the old road, different measures of preventing reflective cracks are put forward, the effect of thickening asphalt layer on the reflection crack is verified, and the design methods of materials and structures of different overlay structures are analyzed and applied to practical projects. It provides some experience and reference for the design of cement pavement overlay in Nanchang city.
