| 路面石油沥青呈弱酸性，与酸性石料互相排斥从而削弱相互间的粘附力。为了改善两者间的粘附力，最终研究出沥青抗剥落剂来解决这个问题。 Pavement petroleum asphalt is weak acidic and repels each other with acidic aggregate, thus weakening the adhesion between them. In order to improve the adhesion between the two, asphalt anti-stripping agent was finally developed to solve this problem. 沥青抗剥落剂作为石料的粘结剂，被人们大范围的使用。掺进抗剥落剂仅使路面层的总造增加5%，但寿命可以提高50%至150%，而维修一次同面积的沥青混凝土路面，单位成本高出新建路面的80%-200%，可见添加剥落剂后的建设、养护合计的单位成本分别下降30%-55% Asphalt anti-stripping agent is widely used as a binder for stone. The addition of anti-stripping agent only increases the total construction of pavement by 5%, but the service life can be increased by 50% to 150%. The unit cost of repairing asphalt concrete pavement of the same area once is 80%-200% higher than that of new pavement. It can be seen that the total unit cost of construction and maintenance after adding stripping agent decreases by 30%-55% respectively. 一般抗剥落剂的用量为沥青重量的0.2-0.5%，推荐用量0.35%-0.4%。使用方法：可直接加入热沥青中(普通沥青温度应不小于130℃，改性沥青温度应不小于160℃)，用搅拌装置搅拌均匀，或者用循环泵循环2次以上。 The dosage of general anti-stripping agent is 0.2-0.5% of asphalt weight, and the recommended shuiniguan.37ix.com.cntaoci.37ix.com.cnchongdian.89ix.comkongzhifa.89ix.compeidiand.89ix.com shiyand.89ix.comdosage is 0.35-0.4%. Usage: It can be directly added into hot asphalt (ordinary asphalt temperature should not be less than 130 C, modified asphalt temperature should not be less than 160 C), stirred evenly by mixing device, or circulated by circulating pump for more than two times. |
