DESIGN OF RIGID PAVEMENTS AS PER IRC

PROBLEM :  Design size and spacing of dowel bars at an expansion joint of concrete pavement of thickness 20 cm.

Given the radius of relative stiffness of 90 cm. design wheel load 4000 kg. Load capacity of the dowel system is 40 percent of design wheel load. Joint width is 3.0 cm and the permissible stress in shear,

bending and bearing stress in dowel bars are 1000,1500 and 100 kg/cm2

respectively.

SOLUTION :
