Modeling road use for capacity loss resulting from pavement distress

Potholing, edge subsidence and pavement cracking under tropical climate are problematic in developing countries. The road use model presented in the paper was formulated to explore the relationship between roadway capacity loss resulting from pavement distress and independent variables such as roadway capacity, road accessibility and road user costs. The paper assumes that density is a resultant of speed/flow on distressed pavement section at capacity, hence not directly affected by poor road condition. This implies that capacity loss is fully the result of speed changes. Based on the circumstances prevalent at the time of survey in Nigeria, a 'with and without' pavement distress study for one direction of the roadway section was conducted. The paper concludes that in the presence of pavement distress, it can be generalized that road use is costly, inefficient and unsustainable.
