Abstract

Using the soil material at the site mixed with adhesives to build roads is an effective solution to reduce construction costs and environmental damage. This paper introduces the process of research and application of rural road construction technology with ON-SITE SOIL mixed with ADHESIVES including: RoadCem (RC), fly ash, ash of Aluminum factory and natural puzolan. (1) RoadCem has the effect of increasing the hydrolysis capacity of the cement when applied to the soil particles, improving the strength of RC-soil-cement, especially the bending strength; (2) fly ash, ash and natural puzolan can replace some cement, ensuring the requirement for rural roads and reducing the cost of construction. The process of receiving and transferring technology, land consolidation principles, some experimental road works, economic efficiency and research orientation will be presented in this article.
