研究了聚丙烯酰胺对水泥混凝土桥面铺装层路用性能的改性效果。结果表明 :聚丙烯酰胺对提高抗折强度、粘结强度、弯曲韧性和抗磨性有显著作用 ,并可降低压折比、渗透性和收缩性。
The modification effect of polyacrylamide on pavement performance of cement concrete deck pavement was studied. The results show that: polyacrylamide to improve the flexural strength, bond strength, flexural toughness and abrasion resistance have a significant role, and can reduce the crimp ratio, permeability and shrinkage.
