摘 要: 分析了沥青混合料组成结构对其高温性能的影响,采用BP神经网络和遗传算法相结合的方法,以高温性能为目标进行了沥青混合料性能优化设计,获得了不同筛孔通过率、粉胶比及空隙率与高温性能之间的关系,为更好地以性能为中心进行沥青混合料设计提供了参考. The effect of constituent structure on rutting performance of asphalt mixtures is analyzed. For the optimizing target of rutting performance, the asphalt mixtures are optimized by combining BP neural net with Genetic Algorithms. The relations between different passing percent, filling-bitumen ratio, voids percent and dynamic stability of asphalt mixture specimen are obtained, which can be consulted in asphalt mixture design based on performances.
