Slag fly ash stabilized macadam base material and preparation method thereof
The invention relates to the technical field of road base construction, and relates to a slag fly ash stabilized macadam base material and a preparation method thereof, the slag fly ash stabilized macadam base material comprises the following raw materials by mass: 60-70 parts of recycled concrete aggregate, 20-30 parts of recycled brick aggregate, 10 parts of recycled mortar, 6-10 parts of blast furnace slag, 0-4 parts of fly ash, 0.4-1 part of an alkali activator, and 9-10 parts of water. According to the invention, skeleton dense gradation is adopted, through hydration reaction of slag fly ash and uniform distribution of fine particles with a particle size of less than 0.075 mm in the recycled aggregate, pores and capillary pores are filled, the pore structure of the recycled aggregate is improved, the compactness is increased, the improvement of the mechanical properties of the whole recycled aggregate stabilized macadam system is promoted, and the comprehensive performance of the recycled aggregate stabilized macadam system is improved. The compressive strength and the splitting strength of the slag fly ash stabilized macadam base material are improved, transverse cracks of a semi-rigid base are reduced, the service life of a pavement structure is prolonged, and the application and popularization value is very good.
本发明涉及道路基层施工技术领域，涉及一种矿渣粉煤灰稳定碎石基层材料及其制备方法，按质量份数计，原料包括以下组分：再生混凝土骨料60～70份、再生砖骨料20～30份、再生砂浆10份、高炉矿渣6～10份、粉煤灰0～4份、碱激发剂0.4～1份和水9～10份。本发明采用骨架密实型级配，通过矿渣粉煤灰的水化反应以及粒径在0.075mm以下的微细颗粒均匀分布在再生骨料中，填充孔隙和毛细孔，改善再生骨料的孔结构和增大密实度的特性，促进了整个再生骨料稳定碎石体系力学性能的提高，改善矿渣粉煤灰稳定碎石基层材料的抗压和抗劈裂强度，减少半刚性基层的横向裂缝，提高路面结构的使用寿命，具有很好的推广应用价值。
