Example 7. What is the spacing between contraction
joints for 4.0 m slab width having thickness of 20 cm
and f = 1.5 for the RCC pavement having 1.0 cm bar
dia at 0.30 in spacing? (take ost = 1400 kg/cm² and
Yc = 2400 kg/m²)
26. Refer to Figure 8 Design 1A attached. For the design of a 4-lane interstate highway, the damage analysis
shown in the figure was performed for a 9.5-inch thick slab according to the PCA design approach. This
analysis indicates that the 9.5-inch thick slab:
a. Only satisfies the fatigue damage condition
b. Only satisfies the erosion damage condition
c. Satisfies both fatigue damage and erosion damage conditions.
d. None of the above
