Road structure processing method based on reinforced alkaline residue improved soil

Abstract

The invention relates to the technical field of road traffic construction, and discloses a road structure processing method based on reinforced alkaline residue improved soil, which comprises the following steps: taking a proper amount of alkaline residue, fly ash and cohesive soil, adding water for mixing by adopting the optimal water content of 23%, and then conducting sealing for 14 days to promote volcanic ash reaction; smearing engine oil in a road structure mold cylinder for lubrication, and packing the mixture into the alkaline residue improved soil in a multi-layer volume-controlled manner; after each layered volume is filled, laying a layer of reinforced material, laying 8-12 cm of alkaline residue improved soil for rolling compaction, and after compaction, sequentially packing the upper-layer mixture until a next-layer reinforcing layer is reached; and circulating and repeating the steps to form the reinforced road structure. Compared with the prior art, the reinforced alkaline residue improved soil is reasonably designed, geogrids and the alkaline residue improved soil are used as raw materials according to the optimal grid spacing, the base layer structure for the solid waste regeneration road is constructed, the design requirements of roads at or below a second level can be met, and resource utilization of alkaline residue solid waste is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of road traffic construction, in particular to a road structure processing method based on reinforced alkali slag improved soil. Background technique [0002] At present, the rapid development of road traffic construction in my country has had a positive impact on the optimization of roadbed performance. In practice, in order to enhance the application effect of roadbed filler, maintain its good functional characteristics, and meet the requirements of driving safety, it is necessary to consider the application of alkaline dregs, control its application process, provide professional support for the potential application value of roadbed filler, and meet road engineering requirements. Science construction requirements. [0003] Since the main components of alkali slag are alkaline compounds such as CaCO3, CaO, and CaCl2, many researchers use it as a part of CaO instead to improve roadbed fillers and base mate...

Problems solved by technology

The countermeasures often need to increase the thickness of the asphalt layer, which increases the construction cost, so this deficiency greatly limits the large-scale application of alkali slag-improved soil base in highway engineering

[0004] However, in addition to geogrids, the existing reinforced soil structures mainly use high-strength fly ash soil, sandy soil, gravel soil, etc. Realize the utilization of solid waste resources
