沥青

An ancient legend explains how pitch lake came to be:many centuries ago two indian tribes fought a great battle.the victorious tribe built a village and held a victory celebration,they killed hundreds of beautiful hummingbirds,ate them,and used their feathers to decorate their clothing.the great spirit was so angered that the birds had been killed that he caused the entire village to sink into the earth.the crater where the village stood has been filled wish asphalt ever since.

一则古老的传说解释了沥青湖的来历：许多世纪以前，两个印地安人部落打了一次大仗，获胜的部落建立了一个村庄，并举行胜利庆典，他们杀死了数以百计的美丽的蜂鸟，吃了鸟肉，并且用鸟的羽毛装饰他们的衣裳；伟大的圣灵被这些蜂鸟惨遭杀害所震怒，便让全村沉入地下。从此，本是这村子原址的陷口便一直注满着沥青。英语知识小品铜，人类学会冶炼的第

In this paper, after consulting vast amount of related literature, considering the long-cycle and low frequency of air temperature, I apply fatigue experiment of asphalt mixture under low temperature and low frequency to research on the thermal fatigue characteristic of asphalt mixture.

本研究在参阅了大量国内外的相关文献后，根据温度循环周期长、频率低的特点，采用沥青混合料的低温低频疲劳试验来研究沥青混合料的温度疲劳特性。

Dynamic frequency sweep and stable flow experiments were conducted on four asphalt mastics consisting of fly ash,limestone,hydrated lime and cement fillers.

通过对粉煤灰、矿粉、消石灰、水泥4种矿物填料组成的沥青胶浆进行动态频率扫描试验和稳态流动试验，对4种不同矿物填料、不同粉胶比对沥青高温性能的影响进行了评价。

With the aid of the (Charge- Coupled Device) CCD camera to acquire the digital informations for erect section of specimens, then utilizing the compacting parameters of compaction particle principal axis direction , asphalt mastics film thickness and particle area ratio etc.

针对沥青混合料试件压实成型方式不同因而内部结构各异的情况，采用图像数字处理技术，借助于CCD相机获取试件立断面的数字化信息，提出利用颗粒主轴方向、沥青砂胶膜厚及颗粒面积比等压实参数，直观、快速而准确地评价不同成型方法的压实效果，在此基础上，选择了马歇尔击实、轮碾压实、振动压实和旋转压实四种方法进行研究，并对比分析了实际路面结构。

Gasoline,diesel oil,LPG,asphalt,SBS modified asphalt waterproof material,etc.

90#汽油，柴油，液化气，沥青，SBS改性沥青防水材料等。

Part of Canada's openness to Chinese investment stems from the sheer cost and complexity of extracting oil from tar sands, which is only profitable when oil prices are high.

加拿大对中国投资的开放部分源于从沥青砂中提取石油的高额成本和复杂技术。只有在石油价格高企的时候，开发沥青砂才是有利可图的。

The results showed that changes of content of saturants, aromatics and asphaltenes were similar during the three kinds of aging test, i.e.

结果表明：在三种老化过程中沥青的芳香分含量均显著减少，沥青质的含量均明显增加，饱和分只有少量的挥发衰减；在短期热氧老化和长期光氧老化试验中胶质含量均降低，但在长期热氧老化中胶质含量增加。

The results showed that changes of content of saturants, aromatics and asphaltenes were similar during the three kinds of aging test, i.e. the saturants content almost kept invariable, the aromatics content obviously decreased and the asphaltenes content remarkably increased.

本文通过室内模拟加速老化试验（短期热氧老化试验、长期热氧老化试验和长期光热老化试验）和对沥青的四组分分析，研究了沥青在拌和、铺筑和使用过程中光氧、热氧老化机理。

First acts according to the asphalt pavement the light thermal environment, has established the asphalt road surface thermal equilibrium equation, to affect the asphalt pavement surface thermal equilibrium temperature each factor level of significance to carry on the analysis, discovered in order to reduce the asphalt pavement surface thermal equilibrium temperature the feasible technical route.

首先根据沥青路面的光热环境，建立了沥青路表面的热平衡方程，对影响沥青路面表面热平衡温度的各个因素的显著性水平进行了分析，以求找出降低沥青路面表面热平衡温度的可行技术路线。
