Heavy structures such as highways, bridges, highway embankments need good foundation soil. The use of natural or man-made fibers in sub grade soils is one of soil improvement technology for heavy projects. Basalt fibers is a naturally obtained inorganic fibers material which has wide use in many industries. Now-a-days the use of basalt fibers in concrete or soil was increased due to its excellent mechanical and environmental friendly properties. On other hand Telangana has a highest red soil deposit which has sand as major composition. Therefore, in this study an attempt is made to find the suitability of locally obtained red soil with the addition of basalt fibers for highway construction. The stabilized soil (soil+basalt) sample is tested for understanding the polypropylene characteristics through resilient and California bearing ratio (CBR) properties. Different percentages of basalt fibers (0%, 0.2%, 0.4%, 0. 6%, 0.8%, 1%, 1.2% and 1.4%) by weight of raw soil is added to the conventional red soil. Stabilized soil was subjected to California bearing ratio (CBR) and proctor compaction test along with preliminary tests. The experimental results shows that the addition of basalt fiber effectively increasing the strength of the soil. Adding of basalt fiber around 0.8% (by soil weight) can significantly enhance the strength of sub grade soil and efficiently improves in the design of pavement structure for highways.
