The order contact of skeleton is similar to that of common traffic and is suitable to be kept between 1.07 and 1.15. When adopting dynamic stability index to evaluate the high temperature performance of asphalt mixture, it is likely to stretch the work of modified asphalt and there is a discrepancy between the capacity to evaluate different gradation designs and the practical facts. In the late process of creep, stiffness module index can evaluate the high temperature performance of asphalt mixture which is relatively objective. The rutting prediction model based on this is relatively reliable.

采用车辙动稳定度指标评价沥青混合料高温性能时，可能夸大了改性沥青的作用，其对不同级配优劣的鉴别能力与实践事实间也存在一定的差异，而蠕变劲度模量指标能够较为客观地评价沥青混合料的高温稳定性能，且在此基础上建立的车辙预估模型经实践检验具有较高的可靠性。

The asphalt is hard and is dug out with a big scoop shovel or a pick,leaving a hole in the surface of the lake.within a week or two the hole is filled with new asphalt that pushes up from below.the supply of asphalt seems to be endless.

湖中的沥青很坚硬，用大勺铲或锄头挖出后，湖面上便留下了一个洞口。一两周内，洞又被地下涌出的沥青填满了。沥青的供应似乎是源源不断的。

The interactions among large air voids, the dynamic hydraulic pressure, the non-uniformly distributed load, the overload, the environment condition and the material lead to the deficiency of the adhesion between asphalt and aggregate. The immigration of the asphalt leads to the new bleeding and inside raveling. The pumping and settlement occurred once the water penetrates the whole asphalt layer.

大空隙率、动水压力、荷载的非均布、超载以及气候条件与路面材料的相互作用造成了沥青与集料粘附性的相对不足，面层内部沥青膜剥落后向上部迁移，这是新泛油、内部松散的产生机理；更为严重的情况下，外界水直接贯穿沥青面层对基层顶面的冲刷将诱发泛浆和沉陷。

Received the asphalt mixture mechanics performance index with frequency through FSCH test, it point out that the complex shearing modulus: G*, G*/sind can appraise the high-temperature performance of different asphalt mixture well. But phase angle: d can't relatively produce quality of high-temperature performance of every asphalt mixture obviously.

通过FSCH试验得到不同频率下沥青混合料力学性能指标，指出复数剪切模量G*、G*/sinδ能较好地评价不同沥青混合料的高温性能，而相位角δ不能明显地比较出各沥青混合料高温性能的优劣。

The paper through the mechanism which produces to the asphalt road surface water harm carries on the induction to summarize, as well as the different type bituminous mixture water stability has carried on a series of contrasts experiment to several kind of different aggregates and the asphalt adherency, has analyzed the aggregate and the asphalt adherency and the bituminous mixture water stability; Meanwhile moves the water action mechanism take the pavement structure in as the key point, in the basis room experiments to the design half rigid base bituminous mixture test sample carries on washes out the experiment, the observation test sample and washes out when the number of times increase along with the time variation the basic unit wash load situation, has analyzed the water to the bituminous pavement various structures level damage rule; To immerses under the condition using the ANASYS finite element software the bituminous pavement structure level the stress to carry on the analysis computation, and analyzed the bituminous pavement according to the computed result to produce the unboiled water harm the rule, further to understand the structure level produced the unboiled water harm the rule.

本论文通过对沥青路面水损害产生的机理进行归纳总结，对几种不同集料和沥青的粘附性以及采用不同抗剥落措施的沥青混合料的水稳性进行了一系列对比试验，分析了集料与沥青的粘附性及沥青混合料的水稳定性，并对水稳性试验进行了评价；同时以路面结构中的动水作用机理为重点，依据室内试验对设计的半刚性基层沥青混合料组合试件进行冲刷试验，观察试件随时间变化和冲刷次数增加时基层的冲刷量情况，分析了水对沥青路面结构层的损坏规律；利用ANSYS有限元软件对浸水前后沥青路面层底应力进行分析计算，并根据计算结果分析了沥青路面产生水损害的规律，进一步了解结构层产生水损害的规律。

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。。。
