超亮牌沥青混凝土用抗裂纤维是以聚酯为原料，经特殊工艺制成，该产品与沥青混凝土中的基料有较强的结合力，纤维与基料的握裹性好，形成均匀连续的多向分布的支撑体系，因而能有助于减弱沥青混凝土的塑性收缩（或膨胀）和冻融时的张力，显著增大路面的韧性，抑制其裂纹产生与发展，减少反射裂纹和冲击破坏造成的开裂，使其抗裂能力显著提高，因此广泛用于高速公路、桥面、机场等工程。

The fiber for bitumastic is a kind of polyester fiber manufactured
by special methods. It can mixed with the concrete very well. It can
greatly reduce the crack and leakage cause of shrinkage and upgrade
the force of concrete, so it make the concrete have good stability,
fray resistance, prolong the life time of concrete. It is widely used
in freeway, airport, bridge, ect.
