工艺和施工设备 |
专用施工设备，细砂和结合料需预混； |
专用施工设备，各种材料单独撒/洒布，根据路况调整撒/洒布量； |
|
层间界面剂洒布量 |
无 |
层间界面剂增加层间粘结力，再生还原老化沥青，洒布量0.1~0.15kg/㎡； |
|
细砂粒径和撒布量 |
40~70目细砂，撒布量0.2~0.4kg/㎡，细砂粒径和撒布量小，抗滑性能保障性差； |
20~70目细砂，撒布量0.4~1.0kg/㎡，根据路况单独调整粒径和撒布量，抗滑性能保障性强； |
|
乳化改性沥青洒布量 |
阴离子慢裂型，软化点≥60℃，与细砂混合喷洒，易堵塞喷嘴，洒布均匀性差； |
阳离子快裂型，软化点≥90℃，shrp性能分级pg82-28，单独喷洒雾化效果好，洒布均匀，洒布量0.4~0.6kg/㎡； |
|
表面保护剂洒布量 |
无 |
表面保护剂增加强度和耐磨性，洒布量0.2~0.4kg/㎡； |
|
使用寿命 |
1~2年 |
2~3年 |
