【摘要】：吉林省早期修建的水泥混凝土路面相当一部分已接近设计年限，有的虽未达到，但由于经济的快速发展导致的交通量剧增，致使水泥混凝土路面的破坏严重，影响了行车的舒适性，降低了使用寿命，急需加铺改建。本文依托省道营白公路项目改造，从实际工程需要出发，在大量病害调研后，以室内研究为基础，分析了水泥混凝土路面病害产生的原因。首先，了解和掌握了原水泥混凝土路面面板的破损状况、面板以及土基的强度情况，，并且对路面结构做出了一定的评价；然后在分析水泥混凝土病害产生原因的基础上，提出了多种路面的修复方法，并修筑了试验路；试验路共有13种路面结构形式，包括：直接加铺沥青混凝土面层、加铺橡胶改性应力吸收层、碎石化改造、加铺半刚性基层、接缝处理加铺结构层等，并进行了试验路长时间的观察。再次，根据水泥混凝土路面的特点，对不同维修方法的路面结构进行了力学分析，在上述的基础上，推荐了水泥路面的维修改造方案；最后，对水泥混凝土路面的施工工艺进行了总结，提出了适合于吉林省气候、车辆组成特点的旧水泥混凝土路面技术。
[Abstract]:A considerable part of the cement concrete pavement built in the early period of Jilin Province has been close to the design years, some of which have not been achieved, but the traffic volume caused by the rapid development of the economy has increased dramatically, resulting in serious damage to the cement concrete pavement. It affects the ride comfort, reduces the service life, and needs to be overlaid and rebuilt. Based on the reconstruction of Yingbai highway project and the actual engineering needs, this paper analyzes the causes of cement concrete pavement disease on the basis of indoor research and a large number of disease investigation. First of all, we know and master the damaged condition of the original cement concrete pavement slab, the strength of the face slab and the soil foundation, and make a certain evaluation of the pavement structure, and then on the basis of analyzing the causes of the cement concrete disease, This paper puts forward a variety of pavement repair methods and builds a test road, there are 13 kinds of pavement structure forms, including: directly overlaying asphalt concrete surface, laying rubber modified stress absorption layer, macadam transformation, adding semi-rigid base, Seams were treated with overlay, and long-term observation was made on the test road. Thirdly, according to the characteristics of cement concrete pavement, the mechanics analysis of pavement structure with different maintenance methods is carried out. On the basis of the above, the maintenance and reconstruction scheme of cement pavement is recommended. Finally, This paper summarizes the construction technology of cement concrete pavement and puts forward the old cement concrete pavement technology suitable for the climate of Jilin Province and the characteristics of vehicle composition.
