Basic Properties of Recycled Aggregate and Engineering Verification of Recycled Road Materials

The feasibility of propagating road materials in the use of contracture wastes especially contented great amount waste bricks were researched in three aspects: Performance of recycled aggregate, engineering verification of renewable road materials and engineering economic analysis. Conclusions are as following: Compared to nature aggregate, recycled aggregate has greater crushing value and water absorption, smaller apparent density and higher mud content and so on. As far as renewable road materials is concerned, it is necessary to consider the wear value and moisture content of recycled aggregate based on the characteristics of recycled aggregate. All structural layers' performances of road meet the design requirements. The economic benefits of the project are significantly.
