岩石纤维对沥青混凝土的韧性影响研究

Study on the influence of rock fiber on the toughness of asphalt concrete

对玄武岩纤维沥青混凝土和普通沥青混凝土开展了韧性的试验研究,玄武岩纤维采用了9 mm和6 mm两种直径,各自掺量选取三个,实验方式采用了间接拉伸试验。研究结果说明:玄武岩纤维的掺加均能够改善普通沥青混凝土的开裂前后变形能力,从而提高普通沥青混凝土的韧性。

The experimental study on the toughness of basalt fiber asphalt concrete and ordinary asphalt concrete is carried out.The basalt fiber adopts two diameters of 9 mm and 6 mm,and the content of each is three.The experimental method adopts indirect tensile test.The results show that the addition of basalt fiber can improve the deformation capacity of ordinary asphalt concrete before and after cracking,so as to improve the toughness of leather asphalt concrete.
