The influence of material selection and mix ratio optimization of cement concrete pavement on road performance

摘要

水泥混凝土路面作为一种常见的道路材料，广泛应用于高速公路、城市道路等建设项目中，其路用性能直接影响到道路的使用寿命和安全性。水泥混凝土路面的路用性能受到多种因素的影响，其中材料的选择和配合比的优化是决定其性能的关键因素。本文研究了不同水泥混凝土材料的选择对路用性能的影响，探讨了水泥、骨料、掺合料等材料对混凝土路面抗压强度、抗折强度、耐久性、抗冻性等性能的作用机制，并提出了配合比优化的方法。通过对比不同材料配比对水泥混凝土路面性能的影响，本文为水泥混凝土路面的设计和施工提供了理论依据，并提出了改善路用性能的优化方案。研究表明，合理的材料选择和科学的配合比优化能够显著提高水泥混凝土路面的使用性能和经济性。

Abstract

Cement concrete pavement, as a common road material, is widely used in expressway, urban road and other construction projects, and its road performance directly affects the service life and safety of the road. The road performance of cement concrete pavement is affected by many factors, among which the selection of materials and the optimization of mix ratio are the key factors to determine its performance. This paper studies the influence of the choice of different cement concrete materials on the performance of road use, discusses the action mechanism of cement, aggregate, admixture and other materials on the compressive strength, folding strength, durability and freezing resistance of concrete pavement, and proposes the method of mix ratio optimization. By comparing the influence of different material ratio on the performance of cement concrete pavement, the paper provides the theoretical basis for the design and construction of cement concrete pavement, and puts forward the optimization scheme to improve the road performance. The study shows that reasonable material selection and scientific mix ratio optimization can significantly improve the performance and economy of cement concrete pavement.
