摘　　要：聚合物改性纤维混凝土(PCC)是一种新型路用混凝土。本文依托武罐高速公路混凝土路面道面工程,通过修正沥青混合料的体积设计法提出了PCC配合比设计方法,在此基础上,通过抗滑性试验对PCC的级配进行了优选。结果表明:聚合物是影响PCC性能的关键因素;改善级配有助于抗滑性的提高;聚合物混凝土不仅具有较高的力学强度,而且具有优良的路表抗滑纹理。Polymer modified fiber reinforced concrete （PCC） is a new way to use concrete. A mix design method of PCC was proposed based on correction mixture volume method of hot mixture asphalt relies on concrete pavement engineering in Wudu to Guanzigou. Based on this, gradation of PCC was selected by compare its skid resistance. The result show that the polymer is a key factor affecting the performance of the PCC. Improving gradation is helps to improve skid resistance. Polymer concrete not only has high mechanical strength, but also excellent road surface skid texture.
