The wuhan university of technology and dongzhou sfrc inc bring forward lsfrc pavement together . lsfrc pavement is a type of new composite pavement by putting certain quantity of steel fiber in the bottom and top of the pavement 该路面是在普通混凝土路面板的底部和顶部一定厚度内撒布一定量的钢纤维铺筑而成的路面，是一种新的复合路面形式。
On the basis of investigation and analysis , the author , directed against such diseases in cement concrete pavement as rupture , hollow , crack and mud - pumping , presents the measures of replacing the whole slab and filling slurry 在调查分析的基础上，针对旧水泥混凝土路面板的断裂、脱空、裂缝和唧泥等病害，提出了整板更换或压浆灌入等方法。
A quasi - elastic method was proposed to decide the maximum load of rigid pavements under static load on the basis of experiments of reduced scale slabs , which was the key point for the similitude law to be used practically 在此基础上给出了基于缩尺板试验的确定刚性路面板静载下的极限荷载的半弹性方法。这是相似规律能应用于工程实际的关键一步。
When the load stress and temperature stress of road slabs combine in a disadvantaged state , pavment structures may be distressed when a large axle load loading one time , the fatigue of pavment structures becomes insignificant 当路面板荷载应力与温度应力的组合处于不利状态时,过大轴载的一次作用就可能造成路面结构的破坏,路面结构的抗疲劳性则无从谈起。
The crux of void detection is how to discern the influence caused by indefinite load - transfer capacity and void separately on deflection . it is apparent that only using deflection as the criterion to detect void is impractical 水泥混凝土路面板下脱空评定的关键是区分接缝传荷不足与脱空分别对弯沉产生的影响，单一利用弯沉指标来评定脱空状况是不完全切合实际的。
3 . based on the analysis of the mechanic characteristics of the earth , a concept , the magnifying effect of the subbase , was proposed to eliminate the disunity in calculations . many facts in concrete pavements can be explained by using this concept 3 、在分析土体力学性质的基础上，提出土基放大效应的概念，解决刚性路面板计算理论不统一的问题，并解释一些刚性板的工作情况。
The rehabilitation agents that consist of epoxy resin emulsion and silicate , suspended substances and etc . used to rehabilitate the cement concrete in american and japan also gain good effect . because all kinds of diseases in the cement concrete pavement exist from south to 本文还介绍了kg型修复材料用于更换填缝料,对水泥混凝土路面板边、板角、裂缝的修复和对水泥混凝土路面坑洞的修复等使用情况。
Meanwhile , the factors causing fissures in the pavement fall into three layers from down to up , namely , the bottom layer of the pavement slab - the formation and fissures & breakage of the transition layer between the pavement and base interface makes the chief reason for the formation of initial cracks and later fissures ; the middle layer - the pavement plate 同时，将路面开裂的影响因素由下而上分为三个不同的层面，即：路面板底层? ?路面与基层界面之间过渡层的形成及其开裂，是导致初始裂缝形成和影响后期开裂的根本原因；中间层? ?路面板体。
The pavement panel , under load and with already existing initial cracking & inherent damaged conditions as well as its cracks & damage , further accumulates and expanses , which lays a foundation for the fissures & breakage ; the surface layer - as the uneven pavement brings about interaction between spring plates which results in impact on the vehicle load , is the main reason speeding up the fissures in the pavement panel 在荷载作用下，使得已经存在初始裂纹和固有损伤条件的路面板，其裂缝和损伤进一步累积和拓展，为路面的断裂破坏奠定了基础；表面层? ?由于路面表面的不平整而引起的车板相互作用带来车辆运动荷载的冲击，是加速路面板断裂的主要原因。
The main contents include : 1 . the mechanics performances of geometrically similar slabs under static load on the same elastic foundation are similar , according to the analysis of slabs with similitude laws and tests of soil stress under rigid pavements with different size ratios . 2 主要内容包括： 1 、根据静力荷载下不同相似比的刚性路面板下的土压力测试结果，结合应用相似理论对弹性地基板所作的分析，指出同一场地土上几何尺寸相似的弹性地基板在静载下的力学性能相似。
