Abstracts: Rigid pavements are those which posses noteworthy flexural strength or flexural rigidity. The stresses are not transferred from grain to grain to the lower layers as in the ease of flexible pavements layers the rigid pavements are made of Portland cement concrete-either plain, reinforced or prestressed concrete. As the rigid pavements slab has tensile strength, tensile stresses are developed due to the bending of the slab under wheel load and temperature variations thus the type of stress develop and their distribution within the cement concrete slab are quite different. The rigid pavement does not get deformed to the shape of the lower surface as it can bridge the minor variation of lower layer. In this project we tried to develop the design of rigid pavement which is good in strength as well as safer for travelling. We have covered, 1) Traffic Input. 2) Load Spectrum Determination. 3) P.C.U and V.D.F. 4) Fatigue Analysis. 5) Design of Slab Thickness, DowelBar, Tie Bar. We have tried to show all the procedures and cautions with significant details and drawings in proper sequence.
