In the known road engineering, geotextile is commonly used as a multi-functional building material, which has shown significant advantages in improving roadbed performance, extending road life and reducing maintenance costs.
Geotextile has the function of strengthening the roadbed. Its unique physical structure can effectively disperse the stress concentration points, increase the integrity and stability of the roadbed, and thus reduce the probability of pavement cracks and depressions.
Geotextile also has excellent waterproof permeability. It can effectively prevent the damage of foundation softening and freeze-thaw cycle caused by water infiltration, ensure the dry state of the roadbed, and reduce the expansion or contraction caused by humidity changes.
Geotextiles can also promote drainage, avoiding water problems by guiding excess water out quickly; And it can isolate materials with different properties to prevent mixing with each other resulting in functional failure.
