摘要
介绍了浦东新区在道路建设实践中总结出的适合水网地区和软土地基地质条件的高等级道路的实用技术。包括:路基工程中的盲沟排水、二灰填浜、石灰土和水泥石灰土;取消砾石砂垫层;小粒径级配二灰碎石基层,水泥稳定碎石或沥青稳定碎石排水基层;次密实沥青混合料和改性沥青SMA面层,以及以超载预压为主的各种桥坡处理措施。
Series of practical technology for senior classified road engineering have been applied to road construction in pudong New Area where soft ground and water net exist, including blind drain, filling creek and ditch with lime and powdery coal ash, lime stabilized soil, cement and Dime stabilized soil, non-gravel course with sand above stabilized road bed, smaller graded crushed rock base course stabilized by lime and powdery coal ash, crushed rock drainage base course stabilized by cement or bitumen, sub-compact bitumen mixtrue and modified bitumen SMA mixtrue. The paper also introduce various consolidate measures of bridge slope subgrade among which pre-overloading method is principal.
