一、坚持“面向经济建设”和“积极稳妥”的方针河南省现有公路3万9千公里,其中黑色路面1万7千多公里,每年实需沥青近10万吨。如何采用新技术节约沥青用量,降低工程造价,延长路面使用寿命,已成为修建沥青路面的当务之急。 1978年至1986年,我省先后参加交通部公路科研所主持的“阳离子乳化沥青的研究课题”协作组,又列为我省的重大科研项目。“六五”期间共铺筑试验路55万4千m~2,同时
First, adhere to the “economic development” and “active and steady” approach Henan Province, the existing highway 39,000 km, of which more than 17,000 kilometers of black pavement, the actual annual need of nearly 100,000 tons of asphalt. How to adopt the new technology to save the amount of asphalt, reduce the project cost and prolong the service life of the pavement has become a top priority for the construction of asphalt pavement. From 1978 to 1986, the province participated in the Collaborative Group of “Research Topics of Cationic Emulsified Asphalt” chaired by the Highway Research Institute of the Ministry of Communications and listed as a major scientific research project of our province. During the “Sixth Five-Year Plan”, a total of 550,000 4,000 m 2 of test roads were paved, meanwhile
