EFFECT OF HIGHWAY CLASS ON FLEXIBLE PAVEMENT SERVICEABILITY

This paper aims to evaluate the effect of highway class on flexib pavement serviceability, using data collected from the road netwo Jordan. To achieve this objective, measurements of surface roughn and distress taken from 18 sections of primary roads and 12 secti of secondary roads were analysed. These data were taken from Elkhatib's study to evaluate pavement performance in Jordan. The objective measures of pavement condition used were longitudinal roughness, and three types of distress (rut depth, cracking, and patching). It was found that the respective proportions of prima pavements in fair, good, and very good condition were 50%, 28%, 2 About half the secondary pavements were found in fair condition, about half in good condition. Multiple regression analysis was performed, to study the effects of highway class and pavement deformation and deterioration on the pavement serviceability inde (PSI). A correlation analysis was performed before developing th regression model. The effect of highway class was found to be significant, and was investigated for three levels of pavement distress. For all classes, the reduction of PSI between levels 1 was greater than between levels 2 and 3. At level 3, the PSI of secondary roads was lower than that of primary roads.
