用针叶木通过真空高温分解生产的木炭作沥青改性剂 ,以不同的含量分别加入两种石油沥青中进行试验 ,结果表明 :用这种针叶木木炭与传统的一种改性剂———商业用炭黑相比 ,不仅使沥青的热稳定性提高 ,而且抗车辙、抗裂缝、防水和抗老化能力都大大增强。WCP 的最佳剂量对SH沥青为 10 %、UM沥青为 5 %。
With softwood softwood pyrolysis vacuum production of charcoal as asphalt modifier, were added to two different levels of petroleum asphalt test, the results show that: with this kind of softwood charcoal with a traditional modifier --- Compared with commercial carbon black, not only to improve the thermal stability of asphalt, and anti-rutting, crack resistance, waterproof and anti-aging ability are greatly enhanced. The optimal dosage for WCP is 10% for SH bitumen and 5% for UM bitumen.
