Abstract

Objectives: Subgrade soil has played an important role in the premature failure of, especially flexible pavement in a hilly area where rainfall intensity is very high. Even a slight failure in subgrade will reflect on the structure of the pavement in terms of cracks, undulations and rutting. An attempt has been made to find the influence of subgrade soil on the premature failure of the road along the State Highway which connects the lifeline between North and South of Mizoram, India. Methods: The locations where early deteriorations took place were located and testing was performed to assess the value of atterberg limits, permeability, bearing capacity, free swell index and hydrophilic coefficient. Findings: Premature failures of pavement are highly influenced by the emanation of groundwater in the form of spring along the hilly side of the road. The deep cutting of the road is not suggested due to the possibility of encountering water seepage. The studies reveal that the value of permeability, CBR value, type of soil, water saturation level and geometry of the pavement has contributed an important role in the performance of the pavement. Novelty: Road cutting at a differential level on sloping terrain results in nonuniform soil strength across the transverse section.

Keywords: Permeability; soil strength; groundwater; premature failure; hill road
