In order to improve the life of cement concrete bridge deck pavement,compound beam test was used to research the fatigue characteristics of hot mixed asphalt courses on bridge deck,finite element analysis method was employed to make the mechanical response of compound beam accord with that of actual bridge deck under the same load,the fatigue test was done for compound beams with different pavement structures.

为了提高水泥混凝土桥面沥青混凝土铺装的使用寿命，以复合梁试验评价不同的桥面沥青铺装结构的疲劳性能，采用有限元法分析荷载作用下复合梁试件具有与实际梁体一致的应力响应，并采用复合梁疲劳试验测试不同桥面沥青铺装层组合的疲劳寿命。

It mainly contains the following things. At first, I bring for the way of anchoring two cementing slabs next to by using dog irons made of iron bars and then cover the surface of the road using bituminous concrete. After analyzing the feasibility of this method by using the famous and popular use soft ware ASYS, the results show the magnitude of the temperature stresses on the limited mat coat of the road has nothing to do with the length of the concrete slabs after covering it with bituminous concrete. Meanwhile, the relative horizontal shifting, the flexural-tensile strain, and the vertical shearing stress of the slabs next to it becomes the least after anchoring them with dog irons made of iron. Therefore it proves that it really works to use this method to prevent and slow down the speed of the reflection cracks in the bituminous concrete skin coat over the old road.

首先，提出采用钢筋马钉锚固相邻水泥混凝土板后再进行沥青混凝土罩面的新方法；采用国际著名的通用有限元软件ANSYS对其可行性进行了分析，结果表明在有限尺寸的板上进行沥青混凝土罩面后，罩面结构的温度应力的大小与板的长度几乎没有关系，同时采用钢筋马钉锚固相邻旧水泥混凝土板后，可以明显地减小相邻板的相对水平位移、接缝处罩面层底部的弯拉应变和垂直剪应变，从而表明该法对防止或减缓旧水泥混凝土路面上沥青混凝土罩面层的反射裂缝是确实可行的。

The changes of penetration,ductility,softening point and viscosity of bitumens at different aging times are analyzed and the critical aging time of bitumens is determined based on these test results.

对原样沥青进行不同时间的老化，测试其在不同老化时间性能指标的变化，利用残留针入度比、残留粘度比、残留延度比和软化点增量等老化指标来分析沥青的老化趋势，确定出了沥青的临界老化时间。

The paper also analyzed production, storage and construction technology, and contrasted the economic and social results of Cold Patch Asphalt Mixture with hot-mix mixture in initial cost and later stage cost.

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。

Applying the technique, some products can be obtained, which reached the standards of Heavy Traffic Modified Asphalt and High Viscosity Asphalt for Drainage Pavement. The effect of technique conditions, including temperature and time, on the mechanical properties of SBS/kaoline compounds and the molecular distribution of SBS were studied.

研究了以高岭土和硅藻土为填料与SBS预先共混，获得了高性能、高温贮存稳定的不饱和聚合物SBS改性沥青，应用此技术获得的产品可以满足重交通改性沥青及透水路面用高粘度沥青的指标。

In the island of Trinidad the oil is in the form famous pitch lake of Trinidad in 1595;it is said to contain nine thousand million tons of asphalt .

在特立尼达岛，石油以沥青—即用作铺路的物质—形式存在。在沃尔特罗利爵士在1595年访问过特立尼达的著名沥青湖，据说该湖的沥青容量有90亿吨。

Tropism properties of particles are used to describe stability and distributing properties of particles to depicting compactness, evaluating parameters of coarse particle in principal axis direction, asphalt mastics film thickness and particle area are used to e-valuate the compacting characteristics.

针对旋转压实法，利用不同压实功作用成型试件模拟压实过程，采用数字图像处理技术，研究沥青混合料的压实成型特性，提出了以集料颗粒的取向特性描述沥青混合料的稳定性，以集料颗粒的分布特性来反映混合料的密实程度，定义了集料颗粒主轴方向、沥青砂胶膜厚及颗粒面积比等参数来进行评价。

Mineral substance mixed between the different particle size pellet to inlay pushes the degree mixed to the asphalt the high temperature stable performance influence to be very big, but could front reflect this pushed the degree was mixed the grading curve trend, through 5 different grading curve trend bituminous mixture high temperature performance conducted the research to the standard scope in, was for the purpose of appraising the different grading curve to move towards to mixed the high temperature performance influence, instructed the highway asphalt mixed the second wife design.

矿质混合了中不同粒径颗粒之间的嵌挤程度对沥青混合了的高温稳定性能影响很大，而能反映这一挤嵌程度的是混合料形成的级配曲线走向，通过对规范范围内5种典型矿物混合料形成的5条不同级配曲线的走向对沥青混合料高温性能进行研究，旨在评价不同矿料级配对混合了高温性能的影响，以指导高速公路沥青混合了的继配设计。
