Abstract:
Regular maintenance is necessary to preserve road investments and reduce users' cost and cost of goods and services, this paper presents the results of study aimed at developing a maintenance priority index for a pavement management system for low volume streets. Maintenance priority index plays a crucial role where forecast results provide a basis for prioritizing road pavement maintenance. Data relating to traffic characteristics, pavement condition ratings, distress types, pavement thickness and roughness index were collected. In this present study the rural roads of Tripura, India which have low traffic volume, has been selected and there structural and functional responses were measured. The relationship between pavement age, CBR of subgrade, traffic, pavement thickness condition indicators such as deflection, riding quality, surface roughness were studied. Maintenance Priority Index (MPI) is developed using three parameters named as deflection, riding quality and traffic to decide the priority.
Keywords: Pavement maintenance; roughness; low volume roads; pavement age; traffic loading.
