PURPOSE:To obtain a slope protection material capable of stably holding sloped ground by mixing soil and sand with processed fibers having specific length and size and specific crimp degree and percentage ratio in a specific weight proportion. CONSTITUTION:A slope protection material is composed of 0.05-6wt% processed fibers of acrylic fibers, etc., having a length of 5-50mm., a size of 3-50 denier, degree of crimp 10 or less, and a crimp percentage 20% or less, and soil and sand. In case where run-off of the slope protection material set on the sloped ground is great, the amount of the processed fibers is controlled to 0.05-2wt%, and 0.2- 2wt% cement is added. When holding the sloped ground by victimizing the growth of plants to some extent, the amount of the processed fibers is controlled to 0.05-1wt% and the amount of cement to be added is controlled to 2- 25wt%. |
