Low-grade highway hot in-place recycling pavement construction method
The invention discloses a low-grade road hot in-place recycling pavement construction method. According to the invention, a certain mass of mineral aggregate is directly pre-scattered on the original pavement, the pre-scattered mineral aggregate and the original pavement are heated together by adopting an infrared heating plate, then the pre-scattered mineral aggregate and the original pavement material are stirred together while the milling drum performs on-site raking, and the milling and mixing rotor adopts a spiral structure, so that the regenerated mixture is gathered towards the center to form a material barrier; and the transverse uniformity of the regenerated mixture is ensured. Meanwhile, original pavement materials can be fully utilized, and the use amount of new materials is reduced, so that the engineering cost is reduced. According to the low-grade road hot in-place recycling pavement construction method, continuous construction can be achieved, milling and transportation are not needed, the construction efficiency is high, and the construction period is short. Compared with a traditional milling and paving technology, the in-place heat recycling technology can shorten the construction period by more than 50%, and the low-grade highway in-place heat recycling pavement construction method can shorten the traffic closing time in the construction process, has small influence on traffic and is beneficial to guaranteeing smooth traffic.
本发明公开了一种低等级公路就地热再生路面施工方法。本发明中，在原路面直接预撒一定质量矿料，采用红外加热板一起加热预撒矿料及原路面，随后铣刨鼓在就地耙松的同时将预撒矿料及原路面材料一起进行搅拌，由于铣刨和拌合转子采用螺旋结构，再生混合料向中央聚集形成料垒，保证了再生混合料的横向均匀性。同时可以充分利用原路面材料，减少新材料的用量，从而降低工程成本。低等级公路就地热再生路面施工方法可以连续施工，无需进行铣刨和运输，施工效率高，施工周期短。与传统铣刨和摊铺工艺相比，就地热再生技术可缩短工期50％以上：低等级公路就地热再生路面施工方法可以减少施工过程中的交通封闭时间，对交通影响小，有利于保障交通畅通。
