The highway geotextile is a new type of civil engineering material. The highway geotextile for expressway construction not only needs to have the tensile properties of the comprehensive mechanical properties under the action of complex stress, but also ensures that the comprehensive energy can not produce obvious attenuation, that is, lasting stability under the long time influence of various natural factors. Qualitative, high and low temperature performance, aging resistance and so on. It
Highway construction is in the ascendant, and the concept of "ecological road and environmental protection road" has been advocated. A large number of expressways and urban expressways have been built throughout the country. There are a lot of small cars and large trucks running on the road, and the relevant departments have been advocating the reasonable transportation, but the excess and overweight vehicles in some areas are still on the road, so the damage to the highway is very big.
At the time of construction, the laying of highway geotextile can improve the bearing capacity of the pavement, and can improve the damage of the structure during the use of the pavement. As the highway geotextile has the effect of shock absorption, and has high elasticity and anti deformation ability, it can make the load and stress more uniform on the pavement. The use of highway geotextile in engineering can also improve the rigidity of pavement and reduce pavement cracks. Highway geotextile can increase the bearing capacity of the embankment itself, because the reinforcement of the fill layer can reduce the fatigue crack of the asphalt concrete pavement, and the geotextile can also prevent the reflection crack on the rigid base.
