一、前言以热熔状态的沥青和一定比例的乳化水溶夜,经过强力的机械混合、揽拌、剪切、研磨、离心等作用,使沥青微滴表面带正电荷均匀稳定地分散于水中,形成茶褐色在常温下水包油(O/W)的乳状液,这种乳液称为阳离子乳化沥青。阳离子乳化沥青在发达的国家已被广泛应用于道路工程中。我国自1978年以来,在全国修路部门引起了越来越广泛的重视。为此交通部转发了国家经委、计委文件,将阳离子乳化沥青筑路、养路技术列为国家重点技术推广项目。要求“七五”期间在全国三分之一的公路路面上使用“阳乳”。
I. INTRODUCTION With the role of hot asphalt and a certain proportion of emulsified water, the asphalt mixture is mechanically mixed, stirred, sheared, ground and centrifuged, so that the surface of the asphalt droplets is uniformly and stably dispersed in the water. The formation of dark brown oil at room temperature (O / W) emulsion, this emulsion is called cationic emulsified asphalt. Cationic emulsified asphalt in developed countries has been widely used in road engineering. Since 1978, our country has drawn more and more attention in the road construction sector nationwide. To this end the Ministry of Communications forwarded the State Economic Commission, Planning Commission documents, cationic emulsion asphalt road construction, road maintenance technology as a national key technology promotion project. He demanded that “Yang Yang Milk” should be used on one-third of the country’s road surface during the “Seventh Five-Year Plan” period.
