本刊应公路交通部门的基层生产单位和读者的意见和要求,以适应我国高等级公路建设和发展的需要,结合生产,系列报道石油沥青性能的研究成果,是十分必要的。为此,在同济大学道交系的支持下,本刊自今年第三期起新辟《石油沥青性能的改善》专题讲座。本讲座共分五讲,其主要内容:石油沥青性状和改性要求;掺用橡胶材料改善沥青性能;掺用树脂材料改善沥青性能;多元复合材料改善沥青性能;沥青性能改善的发展趋向。同时,希望广大读者关心支持这个讲座,并把新的意见与要求及时函告本刊,以利改进和提高。
This journal should be based on the opinions and demands of grass-roots production units and readers in the road transport sector in order to meet the needs of the construction and development of high-grade highways in our country. It is necessary to combine production and series of research reports on the performance of petroleum bitumen. To this end, with the support of Tongji University, Department of diplomacy, this issue from the third phase of this year, the new “improvement of petroleum asphalt performance” seminar. This lecture is divided into five chapters, the main contents of which are as follows: the requirements and requirements of petroleum asphalt; the use of rubber materials to improve the performance of asphalt; the incorporation of resin materials to improve the performance of asphalt; the improvement of asphalt performance of polymer composites; At the same time, I hope that our readers will care about and support this lecture, and will promptly report new opinions and requests to the journal in order to facilitate improvement and improvement.
