Issue/Problem
Effect
Solution
Clear link established between pavement condition and vehicle operating costs and embodied in transport investment models (e.g. HDM-4).
An increase in surface roughness causes vehicle operating costs to increase significant additional costs incurred by road users when maintenance requirements are overlooked.
Identify, program and control maintenance operations
Rate of pavement deterioration is often not contained, causing surface roughness to increase at an accelerating rate
Additional costs to highway users
Use of an appropriate maintenance management system
