Abstract

Load Vehicle Damage Factor (LVDF) on National Highways in the Colombian Caribbean Region

Highlights

Vehicle traffic on roads is one of the most critical input parameters for pavement design, traditionally associated as the element of the greatest uncertainty[1]
Adequate determination of traffic loads is vitally important for road design, since it reduces possible uncertainty this factor causes in determining expected performance in pavement structure
The list of commercial vehicles analyzed under loading and unloaded conditions is presented In Table 3

Summary

Introduction

Vehicle traffic on roads is one of the most critical input parameters for pavement design, traditionally associated as the element of the greatest uncertainty[1]. The greater the existing lags between estimated and actual traffic, the greater the economic damage generated by cost overruns, due to demand overestimation or vehicular traffic underestimation Both situations would cause pavement premature deterioration and increase operating costs for road users. Adequate determination of traffic loads is vitally important for road design, since it reduces possible uncertainty this factor causes in determining expected performance in pavement structure. Some road agencies, such as the American Association of State Highway and Transportation Officials (AASHTO), promote the use of vehicle load spectra as a tool for characterizing traffic for pavement design purposes[2,3]. Traffic characterization in terms of number of equivalent repetitions in the design lane remains valid, as it has traditionally been carried out in many countries
