随着我国大庆、胜利等油田的开采和炼制,大量的国产沥青(渣油)问世。经国内道路部门用国产沥青(渣油)筑路试验,发现除有“老化速度慢”、“施工允许加热范围宽”、“脆点低”等优点外,尚有“热稳性差”“低温变形力弱”,与石料“粘附性差”等不适于路用的缺点,导致路面泛油拥包、裂缝、初期成型慢、寿命短等严重“病害”,影响了道路的使用质量。由于我国石油属性和现行炼油工艺的限制,石油部门暂时生产不出大量合格的路用沥青,道路建设部门不得不自己设法改善国产沥青(渣油)的路用性能。各地经近年来的摸索,已经取
As China’s Daqing, victory and other oil field mining and refining, a large number of domestic asphalt (residue) come out. The domestic road departments using domestic asphalt (residual oil) road test and found that in addition to “slow aging”, “construction allows a wide range of heating,” “brittle point low” and other advantages, there are “poor heat stability” and “low temperature Weak deformation ”, and“ poor adhesion ”of stones, which are not suitable for road use. As a result, serious“ diseases ”such as purse packing, cracks, initial forming slow and short service life of pavements affect the quality of road use. Due to the limitation of petroleum property and current refining technology in our country, the petroleum department can not produce a large amount of qualified asphalt for the time being and the road construction department has to try to improve the road performance of homemade asphalt (residue oil) by itself. Throughout recent years to explore, has been taken
