Public-private partnerships in infrastructure: Managing the challenges. The structural design of pavement for the high-volume roads (as per IRC:37-2018) is proposed by strengthening the conventional subgrade soil layer with TerraZyme and the pavement analysis is carried out. The curing effect on UCS and CBR was investigated. Further, the effect additions of TerraZyme chemical in various dosages to soil were observed in terms of their modified proctor compaction, UCS and CBR values. Initially, tests were carried out to study the mechanical properties like compaction, permeability, unconfined compressive strength (UCS) and California Bearing Ratio (CBR value). The study deals with the improvement in the engineering properties of these soils after subjecting to TerraZyme chemical stabilization. This paper focuses on the effect of TerraZyme stabilization on three types of major soils available in the coastal Karnataka region. By modifying the subgrade soil properties, the crust thickness of the pavement reduces. It is very much essential to improve the soil strength, bearing capacity and other engineering properties to sustain the loads acting on the pavement. The process of changing the engineering properties of natural soil, to improve its strength, bearing capacity and other engineering properties by the addition of suitable stabilizer and admixture is collectively known as stabilization of soil. The pavement is a structure, which is laid to support the wheel load and to spread the load stress to a wider area on the top of the soil subgrade.
