What are the geogrid testing items
Appearance identification. Material overlap. There is no fixed smooth wrinkles, loose
The measured items are divided into the following aspects: the smoothness of the underlying layer and the degree of arch, the width of the lap, the stagger distance of the lapped seam, and the point of the joint
Basic requirements: no aging, no damage, no pollution. Close to the underlying layer, according to the design and construction requirements of laying, tension, fixed, and its lap, bond strength and length should be in line with the design requirements, the upper and lower geosynthetics staggered joints staggered
