石灰粉煤灰稳定土(简称二灰土)具在很高的性价比,因而广泛应用于华北、华东地区高速公路路面(底)基层。文章根据施工中的实际情况,比较了路拌机和站拌和石灰粉煤灰稳定土混合料的施工性能,确定两种拌和设备的适用条件,提出应该根据施工的实际情况确定采用路拌机还是拌和站施工二灰土(底)基层,对不同施工条件下拌和设备的选择有借鉴意义。 Lime fly ash stabilized soil (referred to as two lime soil) with high cost, which is widely used in North China, East China Expressway pavement (bottom) grassroots. According to the actual conditions in the construction, the performance of road mixers and limestone fly ash stabilized stabilized earth mixes is compared, and the applicable conditions of the two kinds of mixing equipment are determined. It is suggested that whether to use road mixers or not Mixing station construction two lime soil (bottom) grassroots, different construction conditions, the choice of mixing equipment for reference.
