Gradient functional bridge deck pavement material and preparation method thereof
The invention belongs to the technical field of bridge deck pavement, and particularly relates to a gradient functional bridge deck pavement material and a preparation method thereof. The gradient functional bridge deck pavement material is prepared from the following components in parts by weight: 10 to 25 parts of pouring type asphalt cement, 75 to 90 parts of mineral aggregate, 1 to 2 parts ofsteel fiber and 0.4 to 1 part of additive, wherein the mineral aggregate comprises light aggregate, common aggregate and mineral powder, and the light aggregate accounts for 1-99% of the total mass ofthe mineral aggregate. The density difference between the light aggregate and the common aggregate and the cementing material is utilized, the paving top surface is enriched with the light aggregate,the effect of enhancing the interlayer shear resistance is achieved, the bottom surface is enriched with the common aggregate and the cementing material, and the deformation compliance is fully exerted. Meanwhile, the weight of the bridge deck pavement can be reduced by 10-60% under the condition that the thickness is not changed, or the pavement thickness can be increased by 1-3 cm under the condition that the dead load is not changed. Furthermore, the purposes of saving high-quality aggregate and protecting the environment can be achieved.
本发明属于桥面铺装技术领域，具体涉及一种梯度功能桥面铺装材料及其制备方法。本发明提供的梯度功能桥面铺装材料，按照重量份数计算，包括如下组分：浇注式沥青胶结料10~25份、矿料75~90份、钢纤维1~2份和外掺剂0.4~1份。其中，矿料包括轻质集料、普通集料和矿粉，轻质集料占矿料总质量的比例为1~99%。本发明利用轻质集料与普通集料和胶结料的密度差，使铺装顶面富集轻集料，起到增强层间抗剪性能的效果，底面富集普通集料和胶结料，充分发挥其变形追从性。同时，可使桥面铺装在厚度不变的情况下减重10%~60%，或保持恒载不变的情况下提升铺装厚度1cm~3cm。进一步，可实现节约优质集料，保护环境的目的。
