Calculate the maximum allowable slab length for a doweled concrete pavement 12 feet wide and 10 inches thick resting on an unstabilized gravel base course with a modulus of subgrade reaction of 200 psi/in. Assume the lowest mean monthly temperature is 60°F less than the mean monthly temperature at placement. The concrete has predominantly limestone aggregate and a tensile strength of 600 psi. Clearly state any other assumptions
