沥青中掺金属皂和PE（聚乙烯）或EPS（聚苯乙烯）可改善其低温性能。我们铺筑了约40万m2的金属皂或其复合改性沥青路面，试验结果表明，路用效果较佳。
Asphalt with metal soap and PE (polyethylene) or EPS (polystyrene) can improve its low temperature performance. We paved about 400,000 m2 of metal soap or composite modified asphalt pavement, the test results show that the road with better results.
