NETWORK-LEVEL ANALYSIS OF STAGED PAVEMENT REHABILITATION AND RECONSTRUCTION

An analysis of the influence of the staged construction on the overall network condition was performed. It investigates the relations between strategies concerning the sequence of rehabilitation works for one-step and staged construction. The road network pavement deterioration and repair were described by means of a controlled nonhomogeneous Markov process. The influence of initial network condition on final condition and users' costs for both one-step and staged construction was studied. It was concluded that the basic relations between strategies for one-step construction remained unchanged in the case of staged construction. Also, there was no difference between the effects considered (backlog, extra users' costs and extra routine maintenance costs) of two types of construction in the first 15 years of a 20-year design period. No reason has been found to improve a greater part of network by measures of shorter service life instead of improving a minor part of network by measures of longer service life.
