Areas found to be unsound or non-durable must be removed and replaced as stated in section 7.5. Dust or other deleterious substances not removed after the initial surface preparation must be vacuumed, leaving the surface dust free and clean.表面处理完成后,检查地坪以保证地坪表面良好、清洁、有合适的纹理且表层结构牢固。如发现有不良不坚实表面,应立即进行处理,具体见第7.5章。经初次表面处理未能移去的灰尘或表面碎屑,应真空吸尘,使地表干净无尘。6.4Removal and Replacem
