oa Civil Engineering = Siviele Ingenieurswese - Rasionele benadering in die ontwerp van buigsame plaveisel



Previous attempts at obtaining a rational solution for the determination of the foundation thickness of a road have been based on the elastic theory with the use of a secant modulus. This modulus incorporates both elastic and certain plastic deformation. These attempts have resulted in designs which are over-conservative, probably because the modulus has too low a value.
