Abstract:
Today, the use of additives to enhance the load-bearing capacity of the soil has been applied to some rural roads in a number of provinces in Viet Nam, proving the outstanding advantages. This paper presents the results of research work and techno-application to rural road construction with on-spot fine basalt soil combined with adhesives including cement PCB۴۰ and additive DZ۳۳. The experimental results show that additive DZ۳۳ has made it possible to increase the hydration ability with cement when effectively reacting with soil particles to reduce construction costs and environmental harms, improve the intensity of reinforced soil mix such as Elastic modulus of reinforced soil (Es), splitting tensile strength (f’st), compressive strength (f’s) and California Bearing Ratio (CBR). Successful application of additive DZ۳۳ combined with cement in soil reinforcement to build rural transport works not only brings about economic efficiency but also, makes use of in-situ fine basalt soil to create a new material for the construction industry, humbly contributing to the study of rural road development in Gia Lai mountainous province in particular and Vietnamese transport infrastructures in general.
