Calculation of pavement thickness using CBR value Studies have shown that there's a relation between CBR value (within a range of 10-12%) and the wheel load, tyre pressure and the thickness of pavement. The expression for pavement thickness is given by: - t (cm) = √ {P [ (1.75÷CBR)- (1÷pπ]} ≫ t (cm) = √ [ (1.75p÷CBR)- (A÷π] Where, p = P/A

(2) The acoustic relaxation times, τ, for these materials is given by: = (3) As an example, if we set η s approximately equal to η b, for water with a viscosity of 0.001 Pa·s(1 cP), the relaxation time is about 10-13seconds. Thus, τ is directly proportional to the viscosity, which can change by many orders of magnitude. A very heavy oil
