The activation energy of epoxy asphalt was lower than that of without asphalt systems.

有沥青的环氧固化体系的反应活化能要小于无沥青的环氧固化体系。

ABSTRACT To modify asphalt is to improve the properties of asphalt.

沥青改性的目的是为了提高沥青的路用性能。

In this paper, SBS modified asphalt was studied through studying the structure and performance of asphalt.

本文主要通过研究沥青的结构与性能进一步探讨了SBS改性沥青体系的性能。

The difference of temperature, pave ply, bestrew detritus diameter between Crumb Rubber Modified Asphalt and SBS Modified Asphalt are considered through the test.

结果表明温度对层间剪应力的影响最大，其次是撒布碎石粒径，再次是铺设厚度，而防水材料的影响最小；并由试验得出最佳胶粉改性沥青防水层设置方案。

The test result shows that, for the asphalt pavement structure with thick hot-mix asphalt course, the influence of flexible or semi-rigid base on pavement rutting is little and perpetual deformation occurs mostly on the top asphalt layer of 20 centimeter depth.

环道试验测定结果表明：对于本试验三种沥青层厚度超过20 cm的沥青路面结构，土基对车辙的影响很小，级配碎石柔性基层和水泥稳定碎石半刚性基层对车辙的影响也很小，路面永久变形主要发生在20 cm深度范围的沥青层内。

If we adopt hot-mix asphalt to construct the asphalt pavement of the tunnel,the heat and harmful gas exhausted by hot-mix asphalt can not be dissipated quickly,so the environment in the tunnel is very uncomfortable,this will affect the construction equipments continuous work and the builders health.

在这样长的隧道中如采用热拌沥青混合料施工，由于隧道空间相对封闭，热拌沥青混合料所释放出的热量和有害气体不能很快排走，使得现场施工环境恶劣，严重影响现场施工设备的正常运转以及施工人员的身体健康。

The results indicate that the μ of the asphalt mixtures has significant effect on the maximal lateral and shear strains. When the modulus ratio of the top and middle lagers is less than 0.8 and the μ of the asphalt top layer increases to a certain extent, the asphalt mixtures around the edge of wheel mark tend to flow towards both sides of the rut under the action of load, leading to the unstable rut.

结果表明，沥青面层的泊松比对沥青路面结构的最大横向应变和最大剪应变有显著影响：当上中面层模量比小于0.8且沥青面层泊松比增大到一定程度时，轮迹带边缘的沥青混合料在荷载作用下有向车辙两侧流动的趋势，容易产生失稳性车辙。

Through some information investigation and pavement crack pouring practices,it is found that as a new material,HR polymer asphalt crack pouring material forming by mixing AH-70# heavy-traffic petroleum asphalt with HR polymer in fixed proportion can by used to repair asphalt pavement cracks,and the effect is good,which has positive significance for prolonging the maintenance period of roads and reducing maintenance costs.

通过一些资料调查及路面灌缝实践发现，将AH-70#重交通石油沥青与HR型聚合物按一定比例掺配合成的HR型聚合物沥青灌缝新材料用于修补沥青路面裂缝，效果较为明显，对延长道路的维护周期、减少养护费用具有积极的意义。

It also analyses the mechanism of SBS modified asphalt.From the changes of the asphalt compose and structure of the fore-and-aft asphalt .

机理分析主要从沥青改性前后的组成和结构变化，来分析它的改性机理。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
