Abstract:
Pavement condition data are collected to assist in making decision on highway maintenance, rehabilitation and reconstruction. To identify the maintenance strategies for a given pavement section one must know both the present and the past deficiencies by some formal rating system. Road riding quality or roughness has the special significance as it has been shown to directly affect vehicle operating cost and road safety, other surface characteristics such as cracking, patching, rutting, raveling, and potholes which affect the riding quality of pavement are related with the structural deterioration of the pavement. So therefore it becomes significant for highway engineer to measure or evaluate the pavement surface characteristics and to measure these, method and the equipment should be fairly simple and fast so that the engineer can make use of them both at the time of pavement construction and maintenance as a quality check. The performance is greatly affected by the type, timeliness and quality of maintenance. The Present Serviceability Index (PSI) is one common evaluator used to describe the functional condition with respect of ride quality. Pavement Condition Index is another index commonly used to describe the extent of distress on a pavement section. Models for the prediction of riding quality are very important to highway agencies for the purpose of managing their road network. The prediction of riding quality is also important for road pricing and regulation studies. Useful models are those that establish the contribution of pavement structure, traffic, environment and any other factors that are relevant for the cost allocation. Appropriate flexible pavement sections were found for the present work done and present serviceability rating studies were carried out. For this three rating panels viz highway panel, non highway panel, and mixed panel with six members in each panel were constituted. An initial orientation program was conducted for the raters for assessing the pavement surface by the both rider rating and visual rating technique. The raters were trained to rate the pavement surface for the pavement surface characteristics. The rating scale adopted for the riding and visual surveys were also supplied to the raters. The field data collected from the selected flexible pavement stretches were used for the analysis of the work. The raw data/ rating was corrected for errors in the individual present serviceability rating for which statistical methods and procedures were used to estimate and remove the errors in the individual present serviceability. The leniency error was determined by calculating mean of individual rater and mean of all single ratings and its correction was also found, the central tendency error was determined by calculating the standard deviation of individual raters and standard deviation of all single ratings were determined. The true ratings were then found and then the corrected mean ratings of all the panels was found for the development of the model and then the validation of the model was done by selecting suitable flexible pavement stretches. The test stretches selected for the development of PSI model were having PSR values in the range of 1.74 to 4.99. The rating studies (both ride and visual) include a subjective method of analysis in which six raters were considered in each panel with a permissible error of -0.28 to 0.15. The leniency error for the rider rating varied in the range -0.06 to 0.04 for highway panel. Similarly for non highway panel -0.011 to 0.29 and -0.09 to 0.13 for mixed panel respectively. The central tendency error for rider rating varied from 0.09 to 0.13 for highway panel, -0.28 to -0.36 for non highway panel, -0.13 to 0.15 for mixed panel. The model developed on above permissible errors was found to be satisfactory for the urban flexible pavement sections.
