摘 要:本文论述了干硬性道面混凝土存在的问题。配制出三种不同强度类型 ,坍落度在 16 0mm以上的流态道面混凝土。提供了各自的配合比。经实测 ,耐久性也随强度提高显著改进。在某工程应用 ,流态道面混凝土在外界少许配合下具有自流平与自密实的性质 ,取消了平板振动器振实作业 ,施工进度提高一倍 ,匀质性得到改善 ,材料费用基本不增加。The thesis expouds the extant problem of the stiff pavement concrete. Three different types of the strength of flowing pavement concrete are compounded, and their slump reach over 160mm. The thesis also provides the mix proportion for each of the types of pavement concrete. The durability is improved as the strength is enhanced. After being applied in some engineering, the flowing concrete begins to possess the qualities of self flowing and self compacting by little cooperating with the outside surroundings. The vibratory compaction of the flat vibrator is dismissed. The construction rate is doubled. The evenness is improved. And the material cost basically needs no increase. 〔
