Fatigue cracking is one of the major modes of premature distresses in asphalt pavements. Cracks of asphalt pavements start as microcracks and later propagate, densify, and coalesce due to repeated traffic loading or low temperature thermal stresses or combinations of both to form macrocracks, and result in structural distresses of asphalt pavements.

疲劳开裂是沥青路面主要的早期破损形式之一，由于交通荷载和低温应力的反复作用，沥青路面中的微裂纹不断扩展、增密并贯穿连通形成宏观裂纹，导致。。。

The process includes making samples using Superpave Gyratory Compactor, selecting gradation by the criterion of stone-on-stone contact and certain air voids in the mix and determining the optimal asphalt content limited by draindown test and expected air voids as the main controllability condition. It is suitable to increase the asphalt content of the mix in the range of expected air voids, which can ensure the compatibility of function and durability of porous asphalt.

该方法采用旋转压实仪成型试件，通过计算法确定初试沥青用量，以石-石接触和一定条件下的空隙率作为设计级配选取的根本依据，在最佳沥青用量的确定中，以沥青析漏损失和空隙率作为主要的控制指标，在设计空隙率的基础上，通过使用纤维增大沥青用量，以保证沥青混合料兼备功能性和耐久性。

In particular, traffic accident, asphalt pavement damage and poor antiskid performance appears to be prominent in the areas of high temperature and rainfall. Thus,It is of great realistic significance to ensure traffic safety and reduce damage in steep road by evaluate accident rates effectively, to design an inerrable structure of asphalt pavement to , to enhance the antiskid performance and the durability of that in asphalt pavement.

在南方高温多雨气候和景区园道陡坡急弯组合情况下，如何保障景区园道交通安全、合理设计防推移破坏的陡坡路段沥青路面结构和材料、提高沥青路面抗滑和抗滑耐久性，对于保障南方景区园道沥青路面的交通安全和道路质量均具有很现实的意义。

The results show that the blacktop performance can be improved efficiently up to existing technical standard if adding properly the reclaiming agent in the outspent asphalt mixture. Some key points are suggested for designing recycled asphalt mixture as blacktop, which may be referable to the design and construction of utilizing recycled asphalt mixture.

结果表明：在旧沥青内添加适宜、适量的再生剂可以有效地改善旧沥青的路用性能，达到规范所规定的技术标准要求；提出了沥青路面混合料再生设计中应该注意的问题，对今后沥青路面的再生设计与施工具有一定的指导意义。

But originally,we had not such kind of superstrong concrete technology,onsy used asphalt concrete to fill it as temporary filling.This could not solved concrete damaged problem,asphalt soften polluted the airplane tires,event to eh plane body.At the same time,floor and running road were also suffered from blace asphalt.This not only caused internal airline company unsatisafction,but also the external airline opinions.

便于工作原来没有如此超早强的混凝土技术，只能用沥青混凝土不断临时填充，这不仅不能彻底解决混凝土破损问题，而且在夏天沥青软化污染了飞机轮胎，甚至溅到机身上，同时停机坪及跑道内也到处是黑色的沥青痕迹/这不仅引起了国内航空公司的不满，而且国外航空公司也有意见。

Now there are many modifiers used in asphalt,but most modified asphalt specification systems are set up on the foundation of base asphalt,and the central issue is how to evaluate all of the modified asphalts properly. What's more,it will give rise to misunderstanding in the application and choice of modified asphalts and it is unfair to some of them.

目前使用的改性沥青品种非常多，但现在的评价规范体系都建立在基质沥青的基础上，如何评价改性沥青，一直是人们争论的焦点，这在使用和选择改性沥青时往往会引起许多误导，对某些改性沥青的应用显得十分不公平。

Here I would sit day after day thinking of Germaine and that dirty little street near the Bastille where she lived, and that buzz buzz going on behind the altar, the buses whizzing by, the sun beating down into the asphalt and the asphalt working into me and Germaine, into the asphalt and all Paris in the big fat belfries.
