    Abstract

    ABSTRACT The study was conducted to investigate the influence of overloaded truck traffic on the pavement damage and its rehabilitation cost of Benghazi Street in Misurata city, Libya. Evaluation of allocated rehabilitation cost also becomes concern of this study to determine the sufficiency of the cost. The objectives of this study are to know the influence of overloaded truck traffic towards the pavement damage; to know the overloaded truck traffic towards rehabilitation cost; and to evaluate sufficiency of the allocated rehabilitation cost based on the actual condition of the pavement rehabilitation needs. Pavement Condition Index (PCI), Equivalent Standard Axle Loads (ESAL) factors calculation were carried out in this study. PCI determined to rate the pavement damage condition based on damage that found at Benghazi Street. ESAL of the traffic determined by AASHTO 1993 standard to get the damage factor due to axle loads. Further the evaluation of allocated rehabilitation cost was conducted based on the ESAL of the traffic by comparing the standard normal ESAL with the ESAL of overloaded truck traffic. The PCI result determined the highest rate of the pavement condition was 71.0 and the lowest one was 6.0. It was retrieved from 21 segments along 2100 meters of Benghazi Street, 17 segments attained under 50 and it was only 3 segments attained above 50 value of PCI. The PCI of total area resumed the value of 31.5 which means a very poor pavement condition rate. In other result, ESAL of truck traffic attained up to 953,230 where the ESAL of normal load determined only 327,964. Ratio of both was 2.90 which mean overload ESAL 290% higher than normal one. The maintenance cost of normal ESAL determined 2.39 dinar Libya/ ESAL and it reached up to 2,276,030.28 dinar. The maintenance cost needs to be adjusted 65% more than allocated maintenance cost. It can be concluded that the maintenance cost for the next periods should be planned well based on the actual ESAL investigation so that it can be managed to suitable cost and sufficient service for safety and comfort of the user.
