由于气温过低的原因,我国北部很多省份公路施工目前已经被迫停工,等待明年春天的来临。然而,随着近年来温拌沥青混合料技术的不断成熟,以及温拌沥青在国内外的成功应用,因为气温过低而暂停公路施工正逐渐变成了历史。温拌技术让路面施工气温门槛下降了10度当前节能减排、保护环境、可持续发展是世界各国共同关注的热点问题,我国也把节约资源作为基本国策。热拌混合料优点突出,路用性能好,是主流技术。但是也有环境污染重,能耗大,沥青老化较严重等明显的缺点。冷拌混合料虽然
Due to the low temperature, highway construction in many northern parts of our country has now been forced to stop work and is waiting for the coming spring. However, with the continuous maturation of warm-mix asphalt technology and the successful application of warm-mix asphalt at home and abroad in recent years, the suspension of road construction is gradually becoming history as the temperature is too low. Warm mix technology makes the pavement construction temperature threshold decreased by 10 degrees The current energy-saving emission reduction, environmental protection, sustainable development is a hot issue of common concern in all countries in the world, China also conserves resources as the basic national policy. Outstanding advantages of hot mix, road performance, is the mainstream technology. However, there are obvious disadvantages such as heavy pollution, high energy consumption and serious aging of asphalt. Cold mix though
