Thermal regeneration asphalt processing technology
The invention discloses a thermal regeneration asphalt processing technology, and relates to the field of asphalt mixtures. The thermal regeneration asphalt processing technology comprises the following steps of: weighing a recycled and crushed asphalt pavement material and a warm mixing agent, mixing and heating the recycled and crushed asphalt pavement material and the warm mixing agent, and heating the mixture to 70-100 DEG C to obtain a first intermediate product; weighing 35-200 parts by weight of a new aggregate, heating the new aggregate to 150-170 DEG C, mixing the new aggregate with the first intermediate product to obtain a second intermediate product, and controlling the temperature of the second intermediate product to 130-160 DEG C; adding 2-6 parts of asphalt into the secondintermediate product, then adding 0.2-1 part of a composite regenerant, mixing, and heating the mixture to 130-150 DEG C to obtain a third intermediate product; and adding 0.5-2 parts of nano carbon black, 1.5-2.5 parts of mineral powder and 0.5-1.1 parts of slaked lime into the third intermediate product, uniformly mixing the materials, and performing discharging to obtain thermal regeneration asphalt concrete. The warm mixing agent is added to heat the recycled and crushed asphalt pavement material, and the compaction and discharge temperature of the recycled and crushed asphalt pavement material can be effectively reduced by the warm mixing agent, so that the effects of saving energy and improving the durability of the recycled and crushed asphalt pavement material are achieved.
本发明公开了一种热再生沥青加工工艺,涉及沥青混合料领域,工艺包括如下:称取回收破碎后的沥青路面材料和温拌剂混合后加热,加热混合料温度至70‑100℃后得第一中间产物;按重量份称取35‑200份新集料加热至150‑170℃后与第一中间产物混合得第二中间产物,控制第二中间产物温度为130‑160℃;向第二中间产物中加入2‑6份沥青,后加入0.2‑1份复合再生剂混合,并加热至130‑150℃,得第三中间产物;向第三中间产物中加入0.5‑2份的纳米炭黑、1.5‑2.5份矿粉和0.5‑1.1份消石灰,混合均匀后出料得热再生沥青混凝土。在加热回收破碎后的沥青路面材料,加入了温拌剂,由于温拌剂能够有效降低回收破碎后的沥青路面材料的压实和出料温度,获得了节约能源,提高回收破碎后的沥青路面材料耐久性的效果。
