聚丙烯纤维碾压混凝土在路面大修工程中的应用

The Application of the Polypropylene Fiber Roller Compacted Concrete under the pavements Overhaul Project

由于交通量的倍增以及超载现象的频繁,许多水泥混凝土路面已经进入大修期。结合岳阳S201铁桃公路大修改造工程,对聚丙烯纤维碾压混凝土的性能进行了试验研究,通过大面积工程应用介绍了该技术的基本原理以及相关的施工工艺,工程实践表明这一技术在旧水泥路面的改造中具有工艺简便、缩短工期、节省投资的特点。

Because of the increasingly heavy traffic and overload, many cement concrete pave- ments are under overhaul period. Based on Yueyang S201 Tietao Highway overhaul reconstruction pro- ject, the author has performed some experimental research into polypropylene fiber roller compacted con- crete. Having introduced the fundamental principles and the related constrution technology of the tech- nique, the project practice has improved that by using this technique, one can simplify the process, shorten the construction period and reduce the cost during the old cement pavement reconstruction.
