Milling-free in-situ cold recycled asphalt pavement maintenance method
The invention relates to the technical field of asphalt pavement maintenance, in particular to a milling-free in-situ cold recycled asphalt pavement maintenance method. The method comprises the following steps of selecting an asphalt reduction regenerant prepared by refining naphthenic crude oil, and uniformly mixing and stirring the asphalt reduction regenerant with water in proportion, pouring the uniformly stirred asphalt reduction regenerant into a special spraying vehicle storage tank, after the special spraying vehicle enters the field, starting a stirrer in a storage tank of the specialspraying vehicle, and continuously stirring for 30 minutes, turning off a stirrer power supply, setting a spraying width according to the width of a construction pavement, selecting a construction advancing direction, and adjusting the position of the special spraying vehicle, according to the determined spraying amount and spraying width of the asphalt reduction regenerant, determining the operation speed per hour of the special spraying vehicle, the ground clearance of a spraying pipe, the spraying pressure, the spraying flow angle and the overlapping width of adjacent spraying belts, carrying out trial spraying on the asphalt pavement for a certain length, so that the asphalt reduction regenerant after trial spraying is uniformly distributed on the pavement, and after trial spraying iscompleted and no error is confirmed, conducting formal spraying construction.
本发明涉及沥青路面养护技术领域,特别涉及一种无需铣刨的就地冷再生沥青路面养护方法。包括选取由环烷基原油提炼制得的沥青还原再生剂,与水按比例混合搅拌均匀;将搅拌均匀的沥青还原再生剂灌入专用洒布车贮存罐内;待专用洒布车进场后,开动专用洒布车贮存罐中的搅拌器,并持续搅拌30min;关闭搅拌器电源,根据施工路面宽度,设定喷洒宽度,并选择施工行进方向,调整专用洒布车位置;根据确定的沥青还原再生剂喷洒量、喷洒宽度,确定专用洒布车的作业时速、洒布管的离地高度、喷洒压力、喷流角度和相邻洒布带重叠宽度;对沥青路面进行试喷一段长度,使试喷后沥青还原再生剂均匀分布在路面上;试喷完成并确认无误后,进行正式喷洒施工。
