依据我国重交通 AH- 70石油沥青技术标准和美国 SHRP沥青路用性能的研究成果 ,对“东方牌”AH- 70石油沥青进行了路用性能的试验研究 ,并与沪宁高速公路使用的 2种名牌沥青进行比较。用“东海牌”AH- 70石油沥青与 2种名牌进口沥青制作 AK- 16 A沥青混合料 ,进行车辙试验和抗水害能力的试验 ,验证了“东海牌”AH- 70石油沥青与 2种进口沥青高温稳定性和抗水害能力相当。
Based on the research results of AH- 70 petroleum asphalt technical standard of China’s heavy traffic and the SHRP asphalt road performance of the United States, the road performance test of “Dongfang” AH- 70 petroleum asphalt was carried out and compared with that of Shanghai-Nanjing Expressway Brand name asphalt for comparison. AK-16 A asphalt mixture was made with “Donghai” AH- 70 petroleum asphalt and two kinds of imported brand asphalt, and the rutting test and water resistance test were carried out. The results showed that “Donghai” AH- 70 petroleum asphalt and two kinds of imported Asphalt high temperature stability and resistance to water damage.
