| 1、在热熔状沥青（改性沥青）中要按照比例来添加沥青抗剥落剂，一般使用量占热沥青比例的0.2%至0.4%，也就是说在每吨沥青中掺入2至4公斤LT-B1/B2的沥青抗剥落剂。如果是在重交道路石油沥青与玄武岩等偏酸性集料下，沥青抗剥落剂的配比用量可以是0.3%至0.4%，如果是改性沥青，用量可以为0.2%~0.3%，但具体的用量还需要由试验之后再确定，均匀掺配后就可得到拌制沥青混合料了。 1, in the hot melt asphalt (modified bitumen) should be in accordance with the proportion to add asphalt antistripping agent, the general use of hot asphalt proportion of 0.2% to 0.4%, that is to say, in the asphalt adding 2 to 4 kg per ton LT - B1 / B2 asphalt antistripping agent. If it is in heavy cross road asphalt with partial acid such as basalt aggregate, the ratio of asphalt antistripping agent dosage can be 0.3% to 0.4%, if it is a modified asphalt, the dosage is 0.2% ~ 0.2%, but the specific amount need to be determined by the test before, even after blending, mixing asphalt mixture can be obtained. 2、在热沥青中沥青抗剥落剂可以直接加入，使用沥青泵进行搅拌；沥青泵是一种容积式泵，具有结构简单、体积小、工作可靠 、噪音低、效率高等特点；采用减速机、调速电机或皮带轮等的传动方式来降低泵转速，以达到理想的效果；循环二次沥青与抗剥落剂就能充分混合了，不需要用其它的搅拌器。 2. The bituminous anti-stripping agent can be added directly in the hot asphalt, and the asphalt pump is used to stir; The asphalt pump is a volume-type pump with simple structure, small volume, reliable work, low noise and high efficiency. The speed of the pump can be reduced by means of reducer, speed regulating motor or pulley, to achieve the desired effect. Cyclic secondary bitumen and anti-stripping agent can be fully blended without any other agitator. |
