摘　　要：浇注式沥青混合料GA和GMA各有一套技术性能评价体系,将这两套技术性能评价体系合并,并分别完成GA和GMA的配合比设计和合并技术指标体系的性能验证。结果表明:在刘埃尔流动性相当情况下,GA的60℃贯入度试验结果、-10℃极限弯曲应变、60℃车辙动稳定度和15℃冲击韧性均显著优于GMA的;GA的60℃马歇尔稳定度和35℃硬度比GMA的差。综合比较认为:GA的整体性能优于GMA。Gussasphalt GA and GMA have their own performance evaluation systems respectively.The two sets of technical performance evaluation systems were combined,and the mix proportion design of GA and GMA and the performance verification of the combined technical index system were completed respectively.The results show that when the Liuer liquidity of the two is equal,the penetration test results at 60℃,the ultimate bending strain at-10℃,the rut dynamic stability at 60℃and impact toughness at 15℃of GA are significantly better than those of GMA.However,the Marshall stability at 60℃and hardness at 35℃of GA are worse than those of GMA.The comprehensive comparison shows that the overall performance of GA is better than that of GMA.
