泡沫沥青是一种不掺化学添加剂它用机械手段使少量的水和沥青发泡的物质,它提高沥青表面活性,便于与砂石料拌和、摊铺和压实.是国际上八十年代发展起来的一项新技术.目前,发达国家的泡沫沥青发生器因采用蒸气为发泡助剂,使得机械结构复杂,价格昂贵.我段经过实验,设计制作成功以普通热水为发泡助剂的 HB—2型泡沫沥青发生器.该发生器由喷嘴、二次发泡箱、热水
Foam bitumen is a kind of non-chemical additive It mechanical means to make a small amount of water and bitumen foam material, which increases the surface activity of bitumen, sand and gravel for easy mixing, paving and compaction. Is the development of the international community in the eighties Of a new technology.At present, the foam asphalt generator in developed countries due to the use of steam as a foaming agent, making the mechanical structure is complex and expensive.I segment of the experiment, the design success of ordinary hot water as a foaming agent HB-2 foam asphalt generator. The generator from the nozzle, secondary foaming box, hot water
