摘　　要：利用智能制造升级版水泥混凝土滑膜摊铺机,使用振捣棒对尚未初凝的混凝土按三维嵌挤结构分割成小块,与振捣棒固定在一起的喷管随振捣棒的移动在割缝内喷入接缝料,形成网状有三维嵌挤特性的柔性接缝膜,构成湿式装配混凝土路面基层结构。用众多接缝替代传统缩缝与胀缝,使网状嵌挤接缝既保持传荷能力,又能分散温缩与干缩变形,并有效约束基层反射裂缝,具有与沥青路面装配式基层完全相同的结构特性。该技术是对滑膜摊铺和装配式基层2个工艺技术的融合与升级,可用于刚柔复合式沥青混凝土路面基层结构的施工。By using cement concrete slipform paver which is intelligent manufacturing upgraded,according to the threedimensional embedded extrusion structure,the concrete not initial set is divided into small pieces by the vibrator.Along with the moved vibrator,the joint material is sprayed into the cutting joint by the nozzle fixed to the vibrator and forms a three-dimensional embedded extrusion characteristics flexible joint film and a wet assembled concrete pavement base structure.Replace traditional contraction joints and expansion joints with many joints produces the following 4 effects:the mesh embedded extrusion joints can not only maintain the load transfer capacity but also disperse the temperature shrinkage and dry shrinkage deformation,the reflection cracks of the base course is effectively restricted and the pavement has the same structural characteristics as the assembly base course of asphalt pavement.This technology is the integration and upgrading of two technologies,i.e.slide film paving and asphalt pavement assembly base.It can be used in the construction of rigid flexible composite asphalt concrete pavement base structure.
