水泥路面板再生集料基层沥青路面性能预测

通过室内试验分析了旧水泥路面板再生集料的技术指标,获取再生集料半刚性基层相关性能。研究结果表明旧水泥路面板再生集料具有良好的路用性能。在此基础上,笔者运用路面设计软件AASHTO 2002 M-E PDG对再生集料半刚性基层沥青路面进行性能预测,讨论新建沥青路面结构组合的可行性,从而为实际工程应用提供理论依据。

Performance Prediction of Recycled Cement Agreggates to Asphalt Pavement Roadbase

The related property of semi-rigid base constructed by recycled aggregates is obtainable through the analysis of the technical indicators on recycled aggregates of the old cement concrete pavement by experiment.The result indicates that the recycled aggregates of old cement concrete pavement remains excellent road performance.And on that basis,with the pavement design software AASHTO 2002 M-E PDG the performance of seme-rigid base asphalt pavement using the material of recycled aggregates is predicted.Moreover,the feasibility of structural composition of new asphalt pavement with an old one has also been discussed which could offer the theory support for the practical engineering application.
