Abstract

The present study carried out to find the characteristic compressive Strength of Rollcrete (RCC) by using accelerated curing method so as to satisfy the required target mean strength in one day and comparing the same results with the normal curing strength at 28 days.
Further, the study is undertaken to design of rollcrete pavements using finite element approach and evaluated the benefit of rollcrete pavement. Considering rutting as a failure criteria, the number of cumulative standard axles required to produce rutting of 20 mm was calculated for M20 and M30 grades of rollcrete pavements. To understand the response of pavement, 2-D axisymmetric finite element modelling is carried out on multi layered rollcrete pavements resting on subgrade soil using commercial software ANSYS. Different combinations of base and rollcrete layer were considered. The study shows that for constant thickness of base, the value of vertical compressive strain at top of subgrade is increases and number of cycles taken by a pavement decreases with decrease in thickness of rollcrete concrete layer.
