SEAM沥青混合料在路面工程中的应用

我国国土面积广阔，气候条件比较复杂，沥青的质量千差万别，特别是许多国产沥青含腊量较高，导致路面病害层出不穷，采用进口沥青、改性沥青价格又比较昂贵,而SEAM沥青混合料是通过在沥青混合料中掺入一定剂量的SEAM改性剂，从而节约沥青，提高混合料路用性能的一种新型、优质的道路材料。在当前可持续发展战略中，SEMA沥青混合料有着广阔的推广空间。

Application of SEAM Asphalt Mixture in Pavement Engineering

Chinese territory is vast, climate condition is complex, the qualities of asphalt are differ in thousands ways, especially the wax content of much domestic asphalt is high, which induce pavement diseases to emerge in endlessly. But import asphalt and modified asphalt are comparative expensive. SEAM asphalt mixture is a new road material with good quality, which is formed through mixing a certain dosage of SEAM modifier in asphalt mixture. It can retrench asphalt and advance pavement performance of mixture. In implementing the sustainable development strategy, SEAM asphalt mixture has broad space for generalizing.
