They drove across the river to New Hampshire on a hot tar road.

他们沿着一条滚烫的柏油路开过了河，来到新罕布什尔州。

Pavement made of layers of compacted broken stone, now usually bound with tar or asphalt. natural road, partly metalled

碎石路用几层集中起来的碎石铺筑的人行道，现在一般与焦油或沥青混合天然道路，一部分铺碎石

It was so hot the tar on the road melted.

天很热，路面上的柏油都软化了。

Did the tar settle on the road?

路上的柏油干硬了 吗 ?

I knew the cobblestones in their layer of tar on the road, and the changing surface of the sidewalk, from flagstones to little lumps of basalt set in wave patterns, tar, and gravel.

我熟悉柏油路上的鹅卵石，人行道上变换的路面，从石板到镶嵌成波浪形的玄武岩碎石块，沥青和砾石。

煤沥青筑路油受氢改质

It was the hydrogen-accepting function of the coal tar pitch that the quality of the coal tar pitch road binder was improved.

橡胶在改质过程中作为供氢媒介参与筑路油的热解反应，正是煤沥青的受氢作用改善了筑路油的质量。
