Abstract: A system for forming a textured surface on a geomembrane (12) includes support surface (20), a first set of rollers (14, 16) for passing the geomembrane, a heater (22) positioned in proximity to the desired surface of the geomembrane to heat the geomembrane to a desired temperature, and a particle distributor (26) positioned above the geomembrane to apply solid particles of desired size and geometry onto the surface of the geomembrane. A second set of rollers (40) is positioned adjacent to the surface to receive the particle-coated geomembrane after the particles have been distributed thereon. The heater includes a preheater (22) positioned on one side of the particle distributor and a postheater (24) positioned on an opposite side of the particle distributor. The preheater (22) serves to elevate a temperature of the surface of the geomembrane prior to receiving particle thereon, while the postheater serves to bond the distributed particles onto the surface of the geomembrane.

Abstract translation: 用于在土工膜（12）上形成纹理表面的系统包括支撑表面（20），用于通过土工膜的第一组辊（14,16），位于土工膜所需表面附近的加热器（22） 将土工膜加热至所需温度，以及位于土工膜上方的颗粒分布器（26），以将所需尺寸和几何形状的固体颗粒施加到土工膜的表面上。 在颗粒分布在其上之后，第二组辊（40）邻近表面定位以接收颗粒涂覆的土工膜。 加热器包括位于颗粒分配器一侧的预热器（22）和位于颗粒分配器相对侧上的后加热器（24）。 预热器（22）用于在接收颗粒之前升高土工膜的表面的温度，而后加热器用于将分布的颗粒粘合到土工膜的表面上。
