温拌沥青混合料是一种新型节能环保材料,拌和温度介于热拌沥青混合料和冷拌沥青混合料之间。与传统的热拌沥青混合料相比,温拌技术降低了矿料、沥青加热温度及混合料施工温度,减轻了沥青因拌和温度过高的老化,延长沥青路面的使用寿命,同时也因为拌和、摊铺温度相对较低,减少废气排放,有利于保护现场施工人员的身心健康。本文通过南通市通沪大道连接线的施工实践,对温拌沥青混合料的路用性能进行验证和研究。
Warm mix asphalt is a new type of energy saving and environmental protection materials, the mixing temperature is between hot mix asphalt and cold mix asphalt. Compared with the traditional hot mix asphalt, the warm mix technology reduces the mineral material, the asphalt heating temperature and the mixture construction temperature, alleviates the aging of the asphalt due to the high mixing temperature and prolongs the service life of the asphalt pavement, , Paving temperature is relatively low, reducing emissions, is conducive to the protection of on-site construction workers physical and mental health. In this paper, through the construction practice of the connecting line of Tonghu Avenue in Nantong City, the road performance of warm-mix asphalt mixture is verified and studied.
