Abstract

In order to examine the effects of 3 kinds of geotextiles (shade net, non-woven fabrics and straw mats) on road slopes in decreasing runoff and soil loss, a self-made rainfall simulator was calibrated and used in a field experiment on slopes of Jing–Cheng (Beijing–Chengde) highway in China. Forty rainfall simulations were carried out on 4 road slopes covered with straw mats, shade net, non-woven fabrics and nothing, respectively. The three kinds of geotextiles all significantly (P < 0.001) decreased runoff and sediment concentration compared with the bare slope. Furthermore, straw mats had the best effect among them, resulting in the lowest runoff coefficient and sediment yield
