Statistical Analysis of Network Level Pavement Maintenance and Management System

This study proposes a reliability-based approach for selecting and validating the schedule for pavement maintenance and management. This requires a comprehensive database of pavement condition, pavement structure, and traffic, as well as a set of tools that allow us to estimate present and future pavement conditions and financial needs. The study considers multi – imperfections, in terms of different treatment and budget availability. Reliability analysis for a multi – objective optimization is integrated to know the treatment effectiveness under varying budgeting conditions. Relationship between the strains at critical locations and varying treatments for road network under different conditions are established and the reliability of these equations are established. The data collected from 4 state highways of 840 km road network in Ramanagara District, Bengaluru is considered for analysis. Relationship between pavement performance parameters and critical strains are developed. Reliability analysis for varying treatment effectiveness based on maximum user benefits and minimum budget availability is discussed. Application of Reliability concepts in pavement maintenance and management helps understand the effect of variability on the quality of the pavements and to plan the timely maintenance strategies, to achieve desirable level of performance during its service life.
