Abstract

Along with the level of traffic congestion on flexible road service and concrete road service which cause various obstacles, namely damage to the part of road construction and reduced service life, the cause of the damage is excessive vehicle load (overload). In this regard, this study will discuss the effect of overload with load variations, namely, standard axle loads of 8.16 tons, 9%, 18%, 27% and 36% more than standard axle loads, so that the effect of overload (overload) to the age of the road service can be known. In calculating the age of road service in this study, supporting data such as average daily traffic data (LHR), CBR data, road geometric data, etc. were obtained from the Office of Public Works and Spatial Planning of Riau Province. The collected data is then analyzed using the Nottingham Design Method to find the required value, then analyze stress and strain for fatigue (ԑt) and deformation (kondisiz) conditions used to calculate the age of the road service. Based on the calculation results it can be concluded that overloaded vehicles (overload) affect the reduction in the age of the road service. Reduction in the design life for fatigue conditions and deformations in standard axle axle loads of 9%, 18%, 27% and 36% more than standard axle loads are 40,8%, %, 63,7%, 76,7%, 84,85% and 25,5%, 43,3%, 55.55%, 65,11%.
