55 Summary The objective of this research was to recommend models for estimating the effects of pavement conditions on vehicle operating costs. These effects are essential to sound planning and management of highway investments, especially under increasing infrastructure demands and declining budget resources.

56 The analysis assumed that there is no interaction between the effect of roughness (unevenness) and surface texture given that their wavelength ranges are independent.

57 this range, an increase in IRI up to 4 m/km will increase repair and maintenance costs by 10% for passenger cars and heavy trucks. At an IRI of 5 m/km, this increase is up to 40% for passenger cars and 50% for heavy trucks.
