Abstract

for the pavements constructed on weak subgrade, Granular Sub-Base (GSB) layer became an important current construction practice of all the national highway projects in India. The recommended stringent specifications for the GSB material and its non-availability due to limited sources is one of the problem in road construction industry. Although in Indian road standards, there is provision for using the locally available materials in GSB layer, but most of these fail to satisfy the recommended specifications. Surkhi is one of the locally available brick kiln waste. This paper summaries the investigation carried out with an objective of developing the GSB mixes using the surkhi as partial replacement of stone dust. The laboratory tests like Grain Size Distribution, Atterberg Limits, Heavy compaction test, Soaked and Un-soaked California Bearing Ratio (CBR) tests were carried out for GSB mixes. Based on the tests results, it is found that Surkhi can be used as an alternative material in partial or full replacement of stone dust in GSB mix. This greatly encourages the utilization of locally available brick kiln waste Surkhi in the construction works of road pavements, this solves the problem of disposal of brick kiln industry waste and bring economy to road construction projects.
