The silica had little effect on the other properties of the modified asphalts.

基质沥青在所测试温度范围内为简单牛顿流体，而聚合物/填料复合物改性沥青为非牛顿流体，在一定的剪切速率下牛顿流体转变为非牛顿流体。

GV value recommended by NCHRP is used to evaluate high-temperature performance of asphalt. In virtue of repeated creep test by different modes and different asphalts, this paper analysis applicability and feasibility of this index which is used for its high temperature pavement performance.

通过对不同沥青进行不同模式下的重复蠕变试验，分析了NCHRP推荐的基于流变模型拟合的GV指标对不同沥青的高温路用性能评价的优势和缺陷所在。

Compared with asphalts,the tensile strength and the fracture elongation rate of the coating obtained increase 10～15 times respectively, and the coating has advatages such as light weight,seamless,easy to maintain and to apply.

这种防水涂料的拉伸强度比沥青的提高了 5～ 10倍，断裂伸长率比沥青的提高了 5～ 15倍，并且具有良好的耐酸碱、耐候和防水性能，涂层轻、无接缝、易修补和施工方便

The general effect of asphalts modifiction was better than that of asphalts modified with SBS/MMT added directly.

王仕峰[5]等通过向SBS中添加碳黑并将该共混物用于沥青改性，结果发现沥青高

The processing technique and technology of prestressed reinforcement and rubber component are based on the combination notion by making full use of intrinsic structure and performing feature of rubber to manufacture the rubber into batten, and using the experience of prestressed reinforcement concrete technology to change the rubber battens into prestressed reinforcement and rubber component.

目前道路路面工程和使用中存在的问题为了说明&预应力钢筋橡胶构件&作为路面材料，具有优于现在普遍使用的沥青和水泥混凝土路面材料的特点，有必要了解目前国内外主干道公路路面材料所使用的沥青和水泥混凝土两种路面材料的特性和存在的问题。

Orthogonal experimental method is used to carry out a test for shearing between waterproof layers. The test is made on crumb rubber modified asphalt and SBS modified asphalt, subjected to different temperature, thickness of paved ply and diameter of bestrewed detritus.

为研究桥面防水粘结层的层间剪切性能，通过正交试验法分别对胶粉改性沥青和SBS改性沥青两种防水材料在不同温度、铺设厚度、撒布碎石粒径下进行了层间剪切试验。

This paper describes the Marshall mix design method of bituminous mixture and its merit and demerit , and makes some suggestions for the design methods and standards in order to obtain high performance bituminous mixture which accords with heavy load and Channelized traffic.

介绍了沥青混合料马歇尔配合比设计方法及其优缺点，并对这种设计方法与设计标准提出一些建议，以设计出符合重载、化交通的高性能沥青混合料。

The cokes are come from aromatics, colloids, asphaltene and Carbenes which are polycondensated and dehydrogenated. The processing of coking in the system are as follows: aromatics－→colloids－→asphaltene－→Carbenes－→cokes.(4) Coking can be avoided in the plasma reactor by feeding coal powder of 40～60 mesh (30%) and coal powder of less than 140 mesh (70%).

3结焦主要发生在等离子体反应较高温区，由煤中的芳香分、胶质、沥青质和碳青质缩聚脱氢形成；装置结焦形成的大体途径为：芳香分－→胶质－→沥青质－→碳青质－→焦质。

Hardening, embrittling and cracking at low temperature of bitumen can be reduced due to improved flexing so as to extend the service life of road and rolling material.

改善沥青的低温屈挠性可减轻沥青低温下的发硬、发脆、龟裂，提高公路、卷材的使用寿命。
