沥青碎石

Hall says one possible safety measure is placing a surface called "crushable concrete" at the end of the tarmac to help stop runaway airplanes.

Hall 说其中可能的安全措施是在碎石和沥青混合的表面铺一种叫&可挤压的水泥&，这种水泥可阻止飞机冲出跑道。

Vicissitudinary changes of temperature and humidity can easily induce shrinkage cracks,and sometimes these cracks reflect to surface of asphalt pavement.

但从多年的实际应用来看，这种水泥稳定碎石在温度或湿度交替变化时容易发生收缩裂缝和干缩裂缝，当沥青面层较薄时，这些裂缝会反射到面层，形成反射裂缝。

Therefore, conducts Asphalt Treatment Base research to have the important application value and the practical significance.

因此，进行沥青稳定碎石研究具有重要的应用价值和实际意义。

New paving road technologies such as asphalt mastic stone pavements, porous pavements ,color pavements are gradually applying in China.

公路建设的发展推动了路面技术的发展，诸如沥青玛蹄脂碎石路面、排水路面、彩色路面等新的铺路技术正逐渐在我国推广应用。

The highway materials used in a wearing surface or surface course can vary from loose mixtures lf soil and gravel to the very-high-quality bituminous mixtures,depending in most countries upon the quality of service required of the highway.

在一个穿用的表面中被用的 2.The 公路材料或表面的课程能从宽松的混合 lf 土壤和碎石变化到那非常-高质量含沥青的混合，在公路是必需的服务品质之上在最大多数的国家中靠。

Then a man called Dunlop invented the pneumatic tire, this along with Macadam inventing the tar road surface made cycling a lot more comfortable.

然后，一个叫邓洛普发明了充气轮胎，这与碎石发明的沥青路面使骑车也舒服多了。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
