Pavement, Rigid Pavement, Flexible Pavement, Flexural Strength.Abstract
A pavement consists of superimposed crusts of chosen and processed materials which are compacted on the base soil or sub-grade. Pavements are made to carry traffic loads and to provide a comfortable surface for vehicles to ply. The main role function of a structure of pavement is to absorb the wheel stress/loads coming on the top crust of the pavement surface and to further distribute that stress on the underlying sub-grade. Generally, there are two kinds of pavements depending on the materials of construction used: Flexible and rigid pavements. Flexible pavements are constructed using asphalt as binder whereas the binder used in rigid pavements is cement. The usage of these two different materials as a binder changes the overall characteristics of the two pavement types. The age, rigidity, load distributing characteristic, and riding quality of the pavements differ exceedingly based on the kind of binder used.
The various kinds of cracks formed on rigid pavement and how these cracks occurs on rigid pavement and how they can be avoided has been discussed in this study. Recommendation has been given keeping in mind IRC 15 2011 and IRC 62 2014 and also for joints.
