Landfills are an essential component of a city’s waste management strategy. Effective management and maintenance of the haul road network within an active landfill ensures efficient operations, level of service and overall effectiveness of the landfill. In early 2011, a study was carried out to assess the condition of the haul road networks within three major active landfills in a large Canadian city. The purpose of this study was to identify and document the road segments within each landfill, determine the condition and structure of each road, and develop maintenance, rehabilitation or reconstruction (M, R & R) strategies based on the collected data. The pavement structures within each landfill consisted of flexible pavements (asphalt concrete), gravel pavements and dirt roads. To identify and document the road segments within each landfill, a unique roadway identification methodology was developed based on sound pavement management principles. The Route ID is a unique identifier which was used to develop a comprehensive pavement management database and to document all road segments within each landfill. The roads within each landfill were then sectioned using digital aerial images and site visits. Pavement attribute data was then collected for each unique identifier. To assess the condition of the pavements, condition surveys and deflection testing using a Falling Weight Deflectometer (FWD) were performed on all road segments. To identify the pavement structure, Ground Penetrating Radar (GPR) surveys and borings were advanced along each road segment. The collected data was then analyzed and used to develop M, R & R strategies for each roadway section. A prioritization methodology was also developed based on traffic levels, pavement thickness and structural condition. The pavement management methodology and prioritization strategy developed as a part of this study can be used by landfill operators to effectively manage their haul road networks and improve efficiency and operation
