Problems solved by technology

[0002] The existing roadbed solidification materials generally use lime, cement and other materials as the main components. Although they can meet the requirements of conventional road engineering, they have the following deficiencies: 1. Lime is a resource building material, and the state restricts its mining. The price is high and the quantity is low. Second, cement production enterprises are high-energy-consuming and high-pollution enterprises. With the increase of people's awareness of environmental protection, they often control their production by means of limiting production, which leads to high cement prices and cannot meet the huge demand for road projects. 3. Cement is a hydraulic material and can only be used normally when the ambient temperature is higher than 4°C; 4. The strength is insufficient. Taking the common notoginseng lime soil as an example, the 7-day unconfined strength is less than 1MPa. The 180-day unconfined strength is less than 1.8MPa, which cannot meet the current requirements of rapid construction and heavy-duty traffic
