| 摘 要： | 为改善现有路面设计寿命不足、实际使用寿命短等问题,从长寿命路面研究出发,探讨了长寿命路面定义及设计要求,结合依托工程的PCC AC长寿命路面结构,采用有限元和路面弹性层状体系理论,分析确定PCC AC长寿命路面的力学模型,对PCC板板底荷载应力和温度应力进行计算分析,并进行路面使用寿命预估,得出理论使用寿命达到40年以上,其寿命符合长寿命路面的设计思想.最后,为增强水泥混凝土与沥青混凝土层间粘结力,研究给出水泥混凝土板裸化时间与技术要求.

| Abstract: | In order to solve such problems as the shortage of design life and actual life of pavement,considering research of long-life pavement,this paper discusses the definition of long-life pavement and design requirements.Based on PCC AC long-life pavement of actual highway,through limited element and elastic layer system theory of pavement,this paper determines mechanics pattern of PCC AC long-life pavement,analyzes load stress and temperature stress of PCC pavement.This paper also gives a structure of PCC AC pavement,and estimates their life.The ideal result is obtained that expecting structure life can last more 40 years,and come up to design thought of long-life pavement.Lastly,in order to enhance the cementing power between cement concrete and asphalt concrete,the baring time of cement concrete and technology reguirements are given according to the research. |
