Embodiment 1
[0035] The present invention uses the concrete road laying method of soil curing agent, comprises the following steps:
[0036] S1. Excavate the roadbed, collect soil samples of the roadbed, and measure the mineral composition and physical and chemical properties of the soil;
[0037] S2. Prepare a suitable soil curing agent according to the mineral composition and physical and chemical properties of the soil obtained in step S1;
[0038] S3, uniformly mixing the soil curing agent with the soil produced after excavating the roadbed to obtain a base soil, laying the base soil evenly on the roadbed to form a base soil layer, and forming a consolidated board after the base soil layer is solidified;
[0039] S4. After leveling the base soil layer, evenly lay cement concrete on the surface of the base soil layer, set up a fine milling layer, spray emulsified asphalt waterproof bonding layer, place steel mesh, lay sand and gravel cushion, and lay asphalt surface layer.

Abstract
The invention discloses a concrete road paving method using a soil stabilizer. The concrete road paving method comprises the following steps: excavating a roadbed, collecting a soil sample of the roadbed, and measuring mineral composition and physicochemical properties of a soil body; preparing an adaptive soil stabilizer according to the mineral composition and physicochemical properties of the soil body; uniformly mixing a soil stabilizer with soil generated after excavation of the roadbed to obtain foundation soil, uniformly paving the foundation soil on the roadbed to form a foundation soil layer, and forming a solidified plate body after the foundation soil layer is solidified; and after the foundation soil layer is leveled, evenly paving cement concrete on the surface of the foundation soil layer, arranging a finish milling layer, spraying an emulsified asphalt waterproof bonding layer, placying a reinforcing mesh, laying a gravel cushion layer, and laying an asphaltsurface layer. The problems that a clay roadbed is poor in resistance and prone to damage are solved.
Description
technical field [0001] The invention relates to a road laying method, in particular to a concrete road laying method using a soil curing agent. Background technique [0002] The subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and spread the load to the depth of the foundation. [0003] Subgrades are often attacked and damaged by changes in natural conditions such as geology, water, rainfall, climate, and earthquakes, and have poor resistance, especially clay subgrades. Clay subgrade roads are often prone to cracking and subsidence. The main reasons are It is because the clay has a high moisture content, ...
