Method for improving expansive soil roadbed filler through combination of plant ash and fly ash
The invention discloses a method for jointly improving expansive soil roadbed filler by plant ash and fly ash, which comprises the following steps: 1, carrying out indoor test on the expansive soil roadbed filler to obtain basic physical parameters of expansive soil, and drying and sieving for later use; 2, plant ash and fly ash are selected as improvement materials, expansive soil improvement samples are prepared according to different mass ratios, and material covering treatment is carried out; and 3, testing the expansion rate and strength of the expansive soil sample before and after improvement to obtain the optimal ratio of the roadbed filler. According to the preparation and application methods of the improved roadbed filler, the improved roadbed filler comprises the following components in parts by weight: 5-20 parts of plant ash and 12-16 parts of fly ash, wherein the total weight of the improved roadbed filler is 100 parts. The plant ash and the fly ash are mixed into the expansive soil, so that the expansion rate of the roadbed filler can be reduced, and the strength of the roadbed filler is improved. The device provided by the invention has the advantages of gradual treatment and low cost, can realize comprehensive utilization of solid wastes, and effectively solves the problem of subsidence and deformation of the expansive soil roadbed.
本发明公开了一种草木灰和粉煤灰联合改良膨胀土路基填料的方法，包括：步骤一：对膨胀土路基填料进行室内试验，获得膨胀土基本物理参数，并烘干过筛备用；步骤二：选择草木灰和粉煤灰为改良材料，按照不同质量比制备膨胀土改良试样，并闷料处理；步骤三：进行改良前后膨胀土试样膨胀率和强度测试，获得路基填料的最优配比。其制备与应用的方法，以改良路基填料的总重量为100份计，其中包含5‑20份的草木灰和12‑16份的粉煤灰。本发明使用草木灰和粉煤灰掺入膨胀土，可降低路基填料的膨胀率，提高路基填料的强度。本发明所提供的放大具有处理渐变，成本低廉的优点，同时能实现固体废料综合利用，有效解决膨胀土路基沉陷变形问题。
