Description 144-151
Pavement performance is associated with the characteristics of soil sub-grade and underlying layers. The poor soil
subgrade and sub-base can deteriorate the overlying upper pavement layers. The weak layers can be improved by
stabilization to get the optimum performance of the pavement. The study is abort stabilized base and sub-base soils using
ordinary Portland cement 43 (OPC 43). With the variation of cement from 1.5% to 7%, stabilized samples have been treated
to have the highest moisture content and dry density possible. An optimization model has been developed for compressive
strength using response surface methodology (RSM). The results have been obtained from the model satisfy the real-life
field conditions. The outcomes suggest that the cement-stabilized gravels meet the compressive strength criteria specified by
the Ministry of Rural Development (MoRD) specifications for rural roads in India.
