Equitable permit fee for overweight trucks

This paper presents a rational approach for determination of permit fees for overweight (OW) trucks based on consumption of service life of highways. The prescribed approach uses mechanistic-empirical design philosophy for estimation of deterioration of the pavement structure. The methodology uses permanent deformation, load-related fatigue damage, and roughness scores as primary descriptors for estimation of the service life consumption for flexible pavements and punchouts and roughness measures for rigid pavements. The experiment factorial included sections with varying structural numbers and slab thicknesses. Each of the pavement sections were simulated under different loading conditions to reflect the full spectrum of axle weights that are characteristic of single, tandem, tridem, and quad axles. This provided the basis for developing the group equivalency (GEF) and axle load factors (ALF) for individual axle groups. This enabled adoption of a modular approach towards determination of gross load equivalencies for any truck category without any restriction on axle weights or configuration. The consumption of the service life was calculated as the additional pavement structure that would be required to accommodate the OW traffic in excess of the design traffic while ensuring the same performance. The cost incurred in the process of providing the additional structure to offset the accelerated consumption was assigned to the responsible truck fleet in proportion to the marginal load equivalency over the legal gross vehicle weight (GVW) and axle weight tolerances.
