When making design with bridge configuration, bridge deck overlay which was only treated as the appendant of bridge, currently not make special calculate and analyze about it, at the same time, current codes also just give directed account for method、material and thickness of deck pavements, there havent any design theory and index to dependent, so it is necessary to do some systemic study about concrete bridge deck overlay and make certain about the stress and distortion characteristic of the deck pavements.

桥面铺装作为特殊的路面结构，它起着保护桥梁和承担路面功能的作用。但是目前，在进行桥梁结构设计时，桥面铺装层只是作为桥梁工程的附属结构，一般不作专门的计算分析，现行规范也只是对桥面铺装的做法、材料、厚度做了指导性的说明，至今没有可以依据的设计理论和指标，因此有必要对桥面铺装展开系统的研究，明确铺装层结构的受力和变形特点。

This paper primary investigates the feasibility and technique of cement stabilized recycled asphalt mixture using in base and subbase course.

Durability tests of the specimen,including tests of abrasion resistance,infiltration resistance,frost resistance(routine frost and coupling with the frost and salt), shrinkage were done.

为了提高路面混凝土的耐久性，通过机理分析，将炼钢时的废渣磨细后，作为第6组分掺入水泥混凝土中，制作了高性能路面混凝土试件，并对掺磨细矿渣高性能路面混凝土试件进行了耐磨性、抗渗性、抗冻性(包括一般冻融和盐冻耦合)及收缩性的试验。

Is it is it gain knowledge to tire and dry to exposed to state frictional force is it is it analyse to go on to commit road surface have to rub to use at first,lagging behind in forming frictional force elasticity on function,glueing and cutting function to analyse a little separately, state the building stones lamination and construct the influence that the depth resist slippery performance to the road surface;Is it is it set up tire sport model to transfer according to elasticity of tire to to slip,is it slip person who move adhere to relation of coefficient with road surface to establish.

首先运用摩擦学知识对轮胎与路面干燥接触状态下摩擦力构成进行分析，分别对构成摩擦力弹性滞后作用、粘着与微切削作用进行分析，说明石料纹理与构造深度对路面抗滑性能的影响；根据轮胎的弹性滑转建立轮胎运动模型，建立滑移值与路面附着系数的关系。

In this paper , a series of surveys on road condition , pavement-performance and destroy reason are analyzed , soil property , hydrologic regime are combined , modulus of resilience are confirmed on heavy compaction test , foundation classification in area of Qinhuangdao is divided into 3 grades and highway is divided into 3 districts according to the principle that different soil grades produce the same effect on thickness of base course or bottom course , Classification of traffic is divided into 4 grades after observation materials of traffic volumes are collected extensively , traffic characters and parameters are analyzed .

本课题在对现有路面结构状况和使用状况进行调查，并对路面使用性能和破坏原因进行分析的基础上，结合秦皇岛地区的土质、水文条件，确定重型击实标准条件下土基回弹模量值，依据不同等级土基对路面基层或底基层的厚度产生大致相同效应的原则，将秦皇岛地区地基强度等级划分为三级并将本地区公路分成三个区。

Combined with the climate feature in frigid zone,this paper states that decreasing broken board in construction,improving road surface frost resistance and assure good usage status is the important part of mixing proportion design of cement- concrete road surface .
