Foamed asphalt warm-mixing recycled pavement construction method
The invention discloses a construction method of a foamed asphalt warm-mixing regenerated pavement. The construction method comprises the following steps: preparation of an ore complexing agent: mixing 5-10 parts by weight of albite, 1-5 parts by weight of potassium feldspar, 1-4 parts by weight of nepheline powder, 1-3 parts by weight of bentonite and 1-2 parts by weight of bentonite; according to the construction method of the regenerated pavement, foamed asphalt is matched with raw materials such as an ore complexing agent, modified aluminum-magnesium hydrotalcite and a whisker reinforcing agent, a formed laying raw material is laid for 5-7 cm through gravel with the particle size of 25-35 cm, a roadbed layer is formed, then gravel with the particle size of 1-3 cm is laid on the roadbed layer, and the laying thickness is 1-2 cm, so that a middle layer is formed; the mixed stirring material in the third step is poured on the middle layer, the laying thickness is 1-5 cm, a foamed asphalt layer is formed, and finally the pavement formed through rolling has excellent water stability, freeze-thaw splitting residual strength ratio and breaking strain.
本发明公开了一种泡沫沥青温拌再生路面施工方法，包括以下步骤：矿石复合剂的制备：将5‑10份钠长石、1‑5份钾长石、1‑4份霞石粉、1‑3份膨润土、1‑2份按照重量比混合。本发明再生路面施工方法中采用泡沫沥青配合矿石复合剂、改性铝镁水滑石、晶须增强剂等原料，形成的铺设原料，经过粒径为25‑35cm的碎石进行铺设5‑7cm，形成路基层，然后再路基层上铺设1‑3cm的碎石，铺设厚度为1‑2cm形成中间层；中间层上浇筑步骤三的混合搅拌料，铺设厚度为1‑5cm，形成泡沫沥青层，最后辊压形成的路面，具有优异的水稳定性、冻融劈裂残留强度比和破坏应变。
