没有热气腾腾的烟雾、没有呛人刺鼻的气味,一辆大型摊铺机缓缓开过后,一条黑黝黝崭新的路面就呈现在眼前。这是连日来在长治路道路养护现场看到的。今年太原市政道路养护中,我市引入了一种“绿色”新材料——温拌沥青混凝土,节能环保,使用后还能减轻路面噪声。 There is no steaming smoke, no choking pungent smell, a large paver slowly opened, a swarthy pavement appeared in front of us. This is the past few days in Changzhi Road maintenance site to see. This year, Taiyuan municipal road maintenance, the city introduced a “green ” new material - warm mix asphalt concrete, energy saving, after use can reduce road noise.
