Mathematics · Contraction Joint Spacing in RCC Pavements
If f = coefficient of friction, A = total area of steel in cm2 across slab width, S = allowable tensile stress in steel in kg/cm2, h = slab thickness in cm, W = unit weight of concrete in kg/m3, and b = slab width in m; what is the spacing formula for contraction joints (LC) in reinforced cement concrete pavements?

- 1LC = 200 × S × Ab × h × W × f✓
- 2LC = 200 × b × h × WS × A × f
- 3LC = 20000 × SW × f
- 4LC = 200 × W × S × bS × h × f
Correct answer
LC = 200 × S × Ab × h × W × f
