PE ground protection mat, which is made by high temperature molding or plasticizing extrusion, is a plastic paving slab used to lay temporary pavement. With great advantages of high pressure resistance, low temperature resistance, UV resistance, chemical corrosion resistance, low water absorption, anti-aging and other excellent characteristics, it is often used in high-speed construction, road construction and construction sites. Laid on muddy or soft pavement, ground protection mat mainly plays the role of support, which can not only quickly provide a safe temporary road for construction vehicles, but also protect plants from being destroyed.
