Statistical analysis shows that bulk density, saturated hydraulic conductivity, and dust on road surface have significant effects on runoff and soil loss. Stone cover may increase surface runoff, but vegetation cover is very effective in erosion control and runoff reduction.

土质道路的容重和路面浮土与径流系数和土壤流失量呈显著正相关，饱和导水率则呈显著负相关；路面杂草能显著减少径流，防治路面侵蚀。

But the research on the low-temperature cracking is still immature up to now, which can justify the absence of related indices of low-temperature cracking of all AC pavement design methods.

但是，从查阅的文献可以看出，对于沥青路面产生低温开裂（包括一次性大幅降温引起的收缩开裂和温度疲劳开裂）的机理，人们的认识是一致的；但是，对于沥青路面低温开裂等问题的研究至今仍不够成熟，世界各国的沥青路面设计方法中均未引入低温开裂的有关指标就说明了这一点。

As can be seen from the literature which I have consulted, universal agreements has been reached as to the mechanism of low-temperature cracking of AC pavement (including contracting cracking cause by one substantial drop in temperature and thermal fatigue cracking). But the research on the low-temperature cracking is still immature up to now, which can justify the absence of related indices of low-temperature cracking of all AC pavement design methods.

Moreover, this kind repairers suitable temperature range is wide, from 0°C to 35° C, and can be used in the whole year. The cement concrete pavement fast repairer has a long time to be used in construction and is easy to operate, so it can be widely used in road construction.This thesis reports the present development situation of Portland cement concrete pavements in Sichuan Province. It focuses on the investigation of pavement conditions in the northern section of Dajian Road, the Chengdu-Longquanyi section of Chengdu-Chongqing Freeway, and Chengdu-Wenjiang-Qionglai Highway.

论文全面总结分析了四川省水泥混凝土路面的发展现状，重点对大件路北段、成渝高速成龙段、成温邛公路三个路段的水泥混凝土路面破损情况进行了调查，分析了主要的破损类型并进而指出了四川省水泥混凝土路面发展中存在的问题。

Firstly,the road area can be detected in homogeneity image and the area out of the road will be wiped off. Then,the color image segmentation will be processing in the road area. After dealing with the segmentation result by some pre-experience,the object can be picked up completely.

先通过均匀性边缘提取找到路面区域并排除路面以外的部分，然后在路面区域内利用彩色图像信息进行分割，并结合先验经验实现目标提取。

In order to improve the planeness and use value of cement concrete pavement and guarantee the high density and planeness of bridge floor like pavement,the article expounds the covering technology which uses slip form spreading machine to connect bridge floor with pavement.

针对提高水泥混凝土路面平整度和使用价值，保证桥面同路面一样具有高密实度、高平整度，为此论述了利用滑模摊铺机将桥面同路面连续一体铺装的施工技术。

The cement coagulation earthen road pavement stave compaction technology is a repair major damage cement road surface new technology, can solve the old cement road surface to spread the reflection crack question which the brea bed produces, has the building cost of projects to be low, the construction is convenient, affects the small merit to the transportation, provides the good driving performance for the newly built road surface.

水泥混凝土路面破碎压实技术是修复严重损坏水泥路面的一项新技术，能够解决旧水泥路面加铺沥青层所产生的反射裂缝问题，具有工程造价较低，施工方便，对交通影响小的优点，为新建路面提供良好的行车性能。

Through a comparison test on the performance of waterproof agents for as- phalt concrete pavement,the article con- cludes that the waterproof agent used in bituminous concrete can effectively seal and block the internal hole of bituminous concrete,and keep the humidity from ente- ring the inner part of concrete....

文章通过对沥青混凝土路面防水剂防水性能进行对比试验，表明沥青混凝土防水剂可以有效的封堵沥青混凝土内部孔隙，防止水分进入混凝土内部，可以起到防水路面水损害的作用，同时指出沥青混凝土防水剂对路面抗滑性能存在负面影响等应注意的问题。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
