设计模拟级配离析、级配离析耦合压实离析的混合料,并运用动水压力试验进行了分析,从保证沥青混合料抗水损坏能力的角度建议了沥青混合料生产和摊铺阶段的级配控制要求。为验证室内试验成果,分别利用级配检验和无核密度仪检测的方法,调查总结了AC-25沥青混合料摊铺离析和压实离析的规律。 Design simulation grade segregation, grading segregation coupling compaction segregation mixture, and the use of hydrodynamic pressure test was analyzed, from the perspective of ensuring the ability of asphalt mixture to resist water damage, the asphalt mixture production and paving stages With control requirements. In order to verify the indoor test results, the rules of grading and compaction segregation of AC-25 bituminous mixture were summarized by the methods of grading test and non-nuclear densimeter respectively.
