【摘要】：“八五”和“九五”期间，广东省修建了大量的水泥混凝土路面。经过20多年的运营，这些早期建设的水泥混凝土路面不约而同的出现各种病害，尤其是近几年来受公路交通量和汽车载重量剧增的影响，越来越多的旧水泥混凝土路面因破损严重的原因需要进行路面大修。“白加黑”能有效地改善旧水泥混凝土路面的使用性能，延长其使用寿命，是旧水泥路面提高路面服务水平的有效手段，可大大改善行车舒适性。因而在现阶段，结合广东省公路路面大修工程设计实例，探讨“白加黑”关键技术是非常有必要的。本文在调查了解广东省省内部分旧水泥混凝土路面大修工程实践的基础上，依托茂（名）至湛（江）高速公路官渡至源水段路面大修工程设计实例，从设计者的角度，通过分析研究“白加黑”的前期准备、方案比选、注意事项等内容，系统的对广东省水泥混凝土路面大修工程“白加黑”关键技术进行了总结。论文着重研究、探讨了旧路面状况调查评价方法、沥青罩面设计方法以及防治反射裂缝措施，并通过在工程实例中进行应用来对相关成果进行了细致、全面的验证，提出了适合广东省路面大修的“白加黑”技术。论文从总结、提炼、研究、引申的角度较为全面的对广东省的“白加黑”关键技术进行论述，可供同行参考。
[Abstract]:During the eighth Five-Year Plan and the Ninth Five-Year Plan period, a large number of cement concrete pavement was built in Guangdong Province. After more than 20 years of operation, these early construction cement concrete pavement appeared various diseases. Especially in recent years, it is affected by the increase of highway traffic and vehicle load. More and more old cement concrete pavement needs to be overhauled because of serious damage. "White plus black" can effectively improve the performance of old cement concrete pavement and prolong its service life. It is an effective means to improve the pavement service level of old cement pavement, and can greatly improve the driving comfort. So at the present stage, combined with the Guangdong Province highway pavement overhaul engineering design example. It is necessary to discuss the key technology of "white plus black". Based on the investigation and understanding of some old cement concrete pavement overhaul engineering practice in Guangdong province, this paper gives a design example of the road surface overhaul project from Guandu to Yuanshui section of Mao (Ming)-Zhan (Jiang) expressway. From the designer's point of view, through the analysis of the "White plus Black" preparation, program comparison, matters needing attention and so on. This paper systematically summarizes the key technology of "white plus black" in Guangdong cement concrete pavement overhaul project. The paper focuses on the research and discusses the investigation and evaluation method of the old pavement condition. The design method of asphalt overlay and the measures to prevent and cure the reflection crack have been used to verify the relevant results in detail and comprehensively through the engineering examples. This paper puts forward the technology of "white plus black" suitable for road surface overhaul in Guangdong province. The paper discusses the key technology of "white plus black" in Guangdong province from the angle of summing up, refining, researching and extending, which can be referred to by peers.
