针对普通路用混凝土抗折强度低、耐久性低和返修率高等特性，拟采用掺加不同含量甲基丙烯酸甲酯及酚醛树脂粉末的方法，利用聚合物改性混凝土的原理，增强普通路用混凝土的路用性能．试验效果表示随着聚合物掺入量的增加，主要路用性能会逐渐增强，在P=7.5％至10％之间效果最优．

Directed at such characteristics of ordinary road concrete as low flexural strength,low dura-bility and high repairing rate,using the method of mixing with different amounts of methyl meth-acrylate and phenolic resin powder,based on the principle of polymer modified concrete,the test is made to enhance the performance of common road concrete.The result shows that,with the in-crease of polymer incorporation,the main road performance will be gradually increased,with the best effect when P is between 7.5% and 10%.
