浇筑式沥青混凝土心墙型式改进的建议

Proposition on improving casting bitumen concrete central core pattern

本文根据浇筑式沥青混凝土主、副心墙材料的性能,分析了沥青混凝土心墙施工或运行中破坏的原因。建议用编织—无纺复合布取代预制块,以避免主、副心墙材料变形性能相差悬殊对心墙运行的不利影响,从而发挥浇筑式沥青混凝土心墙的优越性。

The paper analyses the failure cause in the construction and the operation on basis of the material performance of casting bitumen concrete main and auxiliary central cores, proposes that the precast concrete block is replaced by the weaved -adhesive bonded fabric to avert the unfavorable influence of the core operation due to the great difference of main and auxiliary core material performance to bring the superiority of bitumen concrete core into full play.
