Abstract

The invention provides a road engineering base course and soil road base polymer grouting material. The material is characterized by comprising the following components in parts by weight: 100 parts of metallurgical slag, 30 parts of high-lime fly ash, 10 parts of metakaolin, 1-3 parts of thickening water-retaining agent, 30 parts of alkaline exciting agent and 2-4 parts of additive. The materialhas the advantages of quick setting, early strength, large fluidity and good permeability.

Description

technical field [0001] The invention relates to a polymer grouting material for road engineering bases and soil subgrades, which is used for reinforcing soft soil foundations of road subgrades, road bases, bridge slopes, etc., and belongs to the technical field of road subgrades and bases reinforcement. Background technique [0002] In recent years, Shanghai has spent a large amount of money on the construction of urban road infrastructure, which has greatly improved people's transportation needs. However, due to various reasons such as construction, maintenance, design and increasing traffic flow, some roads have generated a lot of Damage of different nature. However, materials and techniques for repairing such damage are still lacking. The traditional maintenance construction method of massive excavation and replacement blocks traffic and pollutes the environment, which is far from meeting the requirements of the current rapid urban development. Therefore, it is very nec...
