Oyster shell powder desalted sea sand AC-20 asphalt mixture and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to an oyster shell powder desalted sea sand AC-20 asphalt mixture and a preparation method thereof. The oyster shell powder desalted sea sand AC-20 asphalt mixture is prepared from, by mass, 3.0%-3.8% of oyster shell powder; 3.7%-4.3% of asphalt; 23.8%-26.6% of desalted sea sand; 6.4%-9.3% of 4 # broken stone (3-6mm); 15.2%-18.4% of 3 # broken stone (6-11mm); 17.9%-20.5% of 2 # broken stone (11-16 mm); and 25.1%-29.6% of 1 # broken stone (16-22 mm). The oyster shell powder desalted sea sand AC-20 asphalt mixture prepared by the method is a novel building material and has the characteristics of convenience in material taking, energy conservation and environmental protection; a large amount of oystershell powder and sea sand are utilized, the problems of environmental protection and land occupation of oyster shells can be solved, increasingly scarce river sand resources are relieved, the application range of the oyster shells and the sea sand is expanded, various pavement performance indexes of the asphalt mixture meet specification requirements, the cost of used materials is low, and the material cost of the AC-20 asphalt mixture can be reduced; and wide application prospects are realized.
本发明属于建筑材料技术领域，具体涉及一种牡蛎壳粉淡化海砂AC‑20沥青混合料及其制备方法，包括混合均匀的具有以下质量百分含量的各原料组分：3.0%～3.8%的牡蛎壳粉；3.7%～4.3%的沥青；23.8%～26.6%的淡化海砂；6.4%～9.3%的4#碎石(3mm‑6mm)；15.2%～18.4%的3#碎石(6mm‑11mm)；17.9%～20.5%的2#碎石(11mm‑16mm)以及25.1%～29.6%的1#碎石(16mm‑22mm)。本发明制备的牡蛎壳粉淡化海砂AC‑20沥青混合料是一种新型的建筑材料，具有取材便利、节能环保的特点；其大量利用牡蛎壳粉和海砂，可解决牡蛎壳的环保及占有土地问题，并缓解日益短缺的河砂资源，扩大了牡蛎壳和海砂的应用范围，并且其各项路用性能指标均满足规范要求，所用的材料成本低，能降低AC‑20沥青混合料的材料费用，具有广阔的应用前景。
