我国广大的江南地区,由于气候温热潮湿、雨量充沛,且降雨期长,对沥青路面造成的不利影响较为普遍。特别是冬春季节,虽则冰冻只在少部分地区短时发生,但降雨频繁,一般来说,雨期可以从头年十一月断断续续延至次年的六、七月份,严重影响沥青路面的正常养护和施工。阳离子乳化沥青具有不怕潮湿的特性,并具有省能源,少污染等优点,因此用它来作为南方地区的路面粘结材料将是有利的。以交通部公路科学研究所为首的阳离子乳化
In the vast southern part of our country, due to the warm and humid climate, abundant rainfall and long rainfall periods, adverse impacts on asphalt pavement are more common. Especially in the winter and spring, although the freezing occurs only in a few areas for a short period of time, but the rainfall is frequent. Generally speaking, the rainy period can be extended intermittently from November to June or July of the following year, which seriously affects the normal maintenance of asphalt pavement and construction. Cationic emulsified asphalt is not afraid of damp characteristics, and has the advantages of energy saving, less pollution, so use it as the southern area of the road surface adhesive material will be beneficial. Cationic emulsification led by the Ministry of Communications Highway Science Institute
