摘　　要：针对军用机场水泥混凝土具有干硬性和粗集料粒径大等特点,研究出了道面合成纤维混凝土早期抗裂性的试验方法和试验装置。应用该试验方法和试验装置对道面聚丙烯纤维混凝土的抗裂性进行了研究。结果表明:增加聚丙烯纤维的掺量和增长纤维的长度可以有效地阻止道面混凝土早期裂缝的产生。聚丙烯纤维是一种可以在道面混凝土推广应用的新型材料。The early anticrack test method and equipment of pavement synthetic fiber reinforced cement concrete has been researched base on that the military pavement is dry concrete and bigger aggregate size.The anticrack test was done when the different length,the contents of polypropylene fiber by the early anticrack test method on pavement synthetic fiber reinforced cement concrete.The results show that both the lengths and contents of modified polyester fiber increased can make the creak area descend effectively.The polypropylene may be extend in cement oncrete on airfield pavement.
