Study on health preservation technology of ecological insulation cement stabilized gravel layer for Plateau Expressway
The environment in the plateau area is fragile,and the requirements for constructing highways in this area are high.The health preservation process of the water stabilized base has a significant impact on the environment.In order to select a more ecological and environmentally friendly health preservation technology solution while meeting performance requirements,the laboratory experiments and road construction verification of three maintenance methods are studied including the degradable moisturizing film,drip irrigation water-saving moisturizing maintenance and PE film sealing maintenance.The results show that the use of geotextile for maintenance requires a lot of water,and its insulation performance and resistance to shrinkage of cement stabilized crushed stone are the worst.PE film sealing maintenance takes second place,while the degradable moisturizing film has the best effect.
