VVTM design method of brick powder-doped cement stabilized waste concrete recycled aggregate
The invention discloses a VVTM design method of brick powder doped cement stabilized waste concrete recycled aggregate, which adopts a test piece vertical vibration molding method (VVTM) design, and comprises the steps of raw material inspection, aggregate gradation design, optimal brick powder doping amount determination, optimal moisture content and maximum dry density determination, cement dosage determination and the like. Practice data shows that the strength of the cement-stabilized waste concrete recycled aggregate designed by the invention can meet the design requirements of various grades of road bases, and the cement-stabilized waste concrete recycled aggregate can replace traditional cement-stabilized macadam to be used for a road semi-rigid base, so that the construction waste is turned into wealth, and ecological environmental protection and cyclic and ordered development of road construction are assisted.
本发明公开了一种掺砖粉水泥稳定废弃混凝土再生集料的VVTM设计方法，采用试件垂直振动成型方法(VVTM)设计，包括原材料检验、集料级配设计、最佳砖粉掺量确定、最佳含水率和最大干密度确定以及水泥剂量确定等步骤。根据实践数据表明，本发明设计得到的水泥稳定废弃混凝土再生集料强度可满足各等级道路基层的设计要求，可替代传统水泥稳定碎石用于道路半刚性基层，实现建筑垃圾“变废为宝”，助力公路建设生态环保和循环有序的发展。
