The amount <strong>of</strong> additive should be 1-2%. The proper additives are cement or hydrated lime. 2、施工机械与质量检测仪器 Equipment for Construction and Quality Control (1)必须配备齐全施工机械和配件,做好开工前的保养、调试和试机,并保证在施工期间一般不发生有碍施工进度和质量的故障。沥青上面层宜采用机械化连续摊铺作业,对于单幅双车道面层,应实施两台摊铺机梯队作业,以确保摊铺面的质量。因而必须配备以下主要施工机械。 a、橡胶沥青生产设备一套,用管道与拌和楼直接连接,生产经过调试确保沥青泵送系统正常; b、间歇式沥青混合料拌和机。拌和机应配备良好的二级除尘装置; c、沥青混合料摊铺机两台以上; d、非接触式平衡梁装置两套(4只); e、12T以上双钢轮振动压路机4台; f、载重量15T以上的自卸汽车; g、洒水车。 (2)必须配备性能良好、精度符合规定的质量检测仪器,并配备足够的易损部件。主要仪器设备如下: a、针入度仪 b、Brookfield 粘度计 c、软化点仪 d、标准筛(方筛孔) 198
