AH-70石油沥青路用性能的试验研究

Study on the Road Performance of Donghai Brand AH-70 Petroleum Bitumen

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。

It has been carried out the experiments on the performance of Donghai Brand AH 70 petroleum bitumen, the results are compared with those of two other brands of imported bitumen, according to the technological specification of heavy duty AH 70 petroleum bitumen of PRC and SHRP PG Grade. The three AK 16A asphalt mixtures, made from Donghai Brand petroleum bitumen and two other brands of imported bitumen, has been experimented through wheel track test and water resistance test, and the research results manifest that those three brand bitumen are equal in the performance of high temperature stability and water resistance.
