Title:
【発明の名称】半たわみ舗装用一粉型ポリマ―セメント組成物及びその施工法
Document Type and Number:
Japanese Patent JP2534572
Kind Code:
B2
Abstract:
PURPOSE:To shorten the time of application by injecting cement milk which is prepared by mixing a material composed of cement, flyash, quartz sand and re-emulsified powder-like polymer, powder-like additive, into asphalt concrete. CONSTITUTION:20 parts of quartz sand 20, with respect to 100 parts of Portland cement, 40 parts of flyash are taken into a universal kneader for agitating them at a low speed for 10 minutes. Then, thus obtained blend is added thereto with 2.6 parts of ethylene vinyl acetate resin, as re-emulsified powder-like polymer, together with 0.8 parts of water reducing agent and 0.2 parts of deforming agent, and thereafter, it is agitated at a high speed for 20 minutes so as to prepare a blended powder material. Next, the blended powder material is added with 40 parts of water, and is agitated at a low speed for 5 minutes so as to obtain grout which is then injected gaps among aggregates in asphalt concrete having an open particle size corresponding to voids of 22%. Thereby it is possible to obtain a pavement having a flexibility and a rigidity.
