Framework grouting type porous noise reduction concrete pavement material and preparation method thereof
The invention discloses a skeleton grouting type porous noise-reducing concrete pavement material and a preparation method thereof, macroporous concrete is hardened to form a skeleton structure, and then polymer modified cement-based porous grouting material is pressed into the macroporous concrete skeleton structure through high-pressure grouting to form a skeleton structure with the macroporous concrete as a skeleton and the porous noise-reducing concrete pavement material. And the polymer modified cement-based porous grouting material is used as a composite structure system of a filler. The supporting effect of the macroporous concrete framework provides enough strength, the polymer modified cement-based porous grouting material has a large number of communicated and complex pore structures, the excellent sound absorption and noise reduction functions are achieved, meanwhile, falling of aggregate particles of the macroporous concrete framework can be protected, and therefore the durability is improved; the pavement material is reasonable in structural combination, can give full play to the characteristics of the macroporous concrete skeleton and the polymer modified cement-based porous grouting material, and ensures common realization of pavement performance and a noise reduction function.
本发明公开了一种骨架注浆型多孔降噪混凝土路面材料及其制备方法，通过大孔隙混凝土硬化后形成骨架结构，然后通过高压注浆将聚合物改性水泥基多孔注浆料压入大孔隙混凝土骨架结构内，形成以大孔隙混凝土为骨架，聚合物改性水泥基多孔注浆料为填充物的复合结构体系。本发明大孔隙混凝土骨架的支撑作用提供足够的强度，聚合物改性水泥基多孔注浆料具有大量的连通且复杂的孔隙结构，具有优异的吸声降噪功能的同时能够保护大孔隙混凝土骨架集料颗粒的脱落，从而使耐久性得到提高；该路面材料结构组合合理，能够充分发挥大孔隙混凝土骨架与聚合物改性水泥基多孔注浆料的特点，保证路用性能与降噪功能的共同实现。
