oa Civil Engineer in South Africa - The evaluation and prioritization of unpaved road maintenance in developing areas : technical paper

 

Abstract

Road departments in developing areas are responsible for the maintenance of extensive rural road networks, consisting largely of unpaved roads in poor condition. The increase in traffic and the limited funds available have contributed to a need to formalize the identification and prioritization of regravelling and betterment projects of the lower category roads in particular. A method based on the visual evaluation of relevant aspects of unpaved roads is presented. This visual assessment method is incorporated into an algorithm to produce regravelling and betterment maintenance indices. Consistency of results was verified in a validation of the methodology by a panel of engineers and senior personnel involved with road maintenance. Finally, to generalize the algorithm, traffic volumes are taken into account in calculating the priority indices. Guidance is given for the general implementation of this method and algorithm.

Paaiedepartemente in ontwikkelende gebiede is vir die instandhouding van uitgebreide plattelandse padnetwerke verantwoordelik. Hierdie paaie is meestal gruispaaie in 'n swak toestand. Die toename in verkeer en die beperkte beskikbare fondse het aanleiding gegee tot 'n behoefte aan die formalisering van metodes om herbegruisings- en verbeteringsprojekte te identifiseer en te prioritiseer van veral die laer padkategorie. 'n Metode gebaseer op die visuele evaluering van relevante aspekte van gruispaaie, word aangebied. Die visuele evaluering word in 'n algoritme om hergruis- en verbeteringsinstandhoudingsindekse te bepaal, ingesluit. Die bevestiging van die redelikheid van die werkswyse is deur 'n paneel bestaande uit ingenieurs en senior personeel wat met die instandhouding van paaie gemoeid is, verkry. Laastens word die berekening van prioriteitsindekse veralgemeen deur verkeersvolumes in ag te neem. Riglyne word gegee vir die algemene implementering van hierdie metode en algoritme.
