Japan Highway Corporation's Shikoku Branch implemented the vegetation technique to protect cut-slopes along a portion of the Matsuyama expressway in an experimental basis some 16 years ago. A study was carried out to evaluate the effect of slope conditions on the growth of the vegetation and vice versa. The results of the studies after two and ten years since the application show that there is a substantial increase in the number of plants after ten years along with an increased value of plant existence percentage. Comparison of pH values and soil conditions during the time of construction and after 10 years shows negligible change, and mineral study shows a very slow rate of weathering of rock minerals in the slopes. Thus, it can be concluded that the plant roots play an important role in increasing the stability of slopes not only by providing root reinforcement but also by reducing the weathering rate of the rock minerals.
