Why is the roadbed geotextile
Put the geotextile for water treatment
Geotextile is also very many kinds of it, you can say that the specific point of it, geotextile gas barrier to seepage, filter and so on, the general use is to prevent cracks reflected to the above
Reinforcement and isolation of the main reinforcement materials to enhance the shear and tensile deformation of the ability to prevent the road reflection cracks; isolation is the separation of different materials to maintain their performance; because the geotextile itself is not waterproof, in the old road Refurbished over the asphalt mixture will form impermeable composite, in addition to preventing cracks will have a certain waterproof effect.

The roadbed refers to the strip structure that is built on the basis of the route position and certain technical requirements. It is the basis of the railway and the road. The roadbed is a linear structure made of soil or stone. Built in good geological, hydrological, climatic conditions under the roadbed. From the material points, subgrade can be divided into soil subgrade, stone roadbed, earth and rock roadbed three.
