摘要
为了评价沥青面层间黏层油的实际效果,选取苯乙烯-丁二烯-苯乙烯嵌段共聚物改性沥青、苯乙烯-丁二烯橡胶改性乳化沥青、乳化沥青及石油沥青等4种较常用的黏层油,把沥青面层粘结在一起,模拟沥青面层间的实际状态,通过室内拉拔和车辙试验,以抗车辙能力及粘结力为标准对其实际效果进行了试验研究.研究结果表明,喷洒用量为0.2～0.3 kg/m2的苯乙烯-丁二烯-苯乙烯嵌段共聚物改性沥青和苯乙烯-丁二烯橡胶改性乳化沥青粘结效果较好.
With the anti-rutting ability and cohesive force as evaluation standard,rutting and drawing tests were performed on bituminous concrete mixtures which use styrene-butadiene-styrene （SBS） block copolymer modified asphalt styrene- butadiene-rubber （SBR） modified emulsified asphalt,emulsified asphalt and petroleum asphalt as tack coat oil to evaluate the real effect of the tack coat oil on bituminous surface course. The results indicate that SBS block copolymer modified asphalt and SBR block copolymer modified emulsified asphalt exhibit excellent performance when the application amount ranging from 0.2 to 0.3 kg/m^2.
