Question
Consider the following data for a plain cement concrete pavement:
Width of expansion joint gap = 2.5 cm
Temperature variation between summer and winter = 30°C
Coefficient of thermal expansion of concrete, C = 10-5 per °C
Coefficient of friction, f= 1.5
Unit weight of concrete, W = 2400 kg/m3
Allowable tensile stress in concrete pavement, SC = 0.8 kg/cm2
The expansion joint and contraction joint spacing LS and LC respectively of the pavement are
Ls = 3.5 m and Lc = 41.67 m
%3D
A
Ls = 41.67 m and Lc = 3.5 m
C
Ls = 41.67 m and Lc = 4.44 m
D
Ls = 4.44 m and Lo = 41.67 m
