一、前言随着我国工农业生产的发展,公路交通运输日益繁重,对沥青路面的技术要求随之提高。沥青路面质量的好坏,在很大程度上与沥青本身的品质有关。但国产沥青的路用性能差,需加改善,过去很多单位曾对此进行了研究,如将渣油氧化、掺配提高稠度、调整骨料级配,严格控制用油量等措施,在一定程度上提高了沥青路面的热稳性,避免了夏天出现严重泛油 I. Introduction With the development of industrial and agricultural production in our country, the road transport is becoming more and more heavy, and the technical requirements for asphalt pavement are increasing. Asphalt pavement quality is good or bad, to a large extent, the quality of the asphalt itself. However, the road performance of domestic asphalt is poor, need to be improved, many units in the past have conducted a study, such as residue oxidation, blending to increase consistency, adjust aggregate gradation, strict control of oil consumption and other measures, To some extent, the thermal stability of asphalt pavement is improved, avoiding the serious oil pan in the summer
