Road Construction Fabric have the function of filtration, which is mainly used to control pollution. For example, at the construction site, countless soil and dust were stirred up during the work. When it rains or drains here, the soil can enter the canal and block it. Road Construction Fabric can be installed near the construction site to prevent soil erosion. When geotextiles are used for reservoir and roadway management, the filtration function can also be used. Another effect is reinforcement, such as levees or embankments, in the course of work, or in bad weather trends, soil and rock may fall. We can use filament Geotextiles to protect dams and slopes. It can stabilize slopes with roots of plants and provide stable protection.

The long wire Road Construction Fabric must meet the strength requirements. The porosity of the geotextile should be able to guarantee the immersion of the asphalt. The melting point of the long wire geotextile must be higher than the paving temperature of the hot bitumen. Taking the common AH-90 petroleum asphalt as an example, the normal paving temperature is at 110~165, polyethylene melting point 125~165, polypropylene 165~173 and polyester 220~230, because the material of the filament geotextile is polyester, so it meets the requirement of temperature. The effect of filament reinforced geotextile on preventing reflection cracks is enhanced. Even thinner asphalt overlay thickness, filament geotextiles can effectively prevent crack reflection. The control effect of the filament geotextile for the fatigue crack less than 3mm is better. The concrete measure is to lap the fabric with hot bitumen on both sides of the crack, and to fill the crack in advance for the crack larger than the 6mm.
