Hi All,
Is there an empirical formula to calculate K[sub]0[/sub]- modulus of dowel support for a given dowel and concrete type? or maybe a table for typical dowel used in a rigid pavement?
K[sub]0[/sub] - the reaction per unit area due to applied load when the deflection is equal to unity. I can only find a range figure (300-1500 -ksi/in)which doesn't help to size a dowel.
The stress on the concrete from the dowel is directly proportional to K[sub]0[/sub]and the dowel deflection. So if for example, the dowel deflection is 0.01in using the range of figure the concrete stress could vary 3000 to 15000 psi?
Many thanks.
