Abstract
In the present study, ananalysis has been made for thevehicle operating cost with theexisting road maintenance system, which is based ona road roughness progression during the age of the unmaintained pavement, andthe same has been compared with the timely maintained road. A sixty-two km road length of existing National highway from Madhya Pradesh was selected for study purposes.Based on road roughness progression, the age of the pavement, and future traffic projections, the complete rehabilitation module was designed,and low-cost maintenance treatments were proposed throughout the design life of the pavement to maintain theroad surface roughness, and the structural stability as per the requirement of the road users.Accordingly, vehicle operating cost was estimated for the design period of Ten years for both options. The classification of the vehicles considered are new technology cars (NTC), two-wheelers (TW), buses, light commercial vehicles (LCV), and multi-axle heavy commercial vehicles (HCV).The VOC has been computed by using models developed by Dr. L.R. Kadiyali& Associates and Dr. Reddy 2003 with some modifications in the price rise factor, which has been kept at 1.75 due to an increase in the cost of fuel and spare parts of the vehicle.Structural strength, future traffic growth, width, age, and roughness of pavement were considered as main parameters.The study shows that thin renewalsstartfrom rating good with an initial roughness of 1.798 meters/Km and end with a roughness of more than 5.5 meters/Km, and causeheavy vehicle operating costs. Whereas as well-maintained road throughout the design life starts with an initial roughness of 1.8 meters/Km and ends in rating good with a roughness of 2.5 meters/km. Itprovides a benefit to road users andis highly cost-effective
