Effect of Increased Asphalt Pavement Density on its Durability

The overall objective of this demonstration project is to evaluate the effects of increasing the initial in-place density of asphalt pavements on their potential field performance. Specific objectives are to identify efficient methodology for achieving the increased in-place density of asphalt pavements with minimal additional costs and without damaging the aggregate structure, construct a demonstration pavement section that includes a control section (meeting the current minimum density requirement) and test section (having an average of 1.5 percent increase in-place density), evaluate volumetric properties of laboratory and field asphalt samples, and evaluate laboratory performance characteristics of laboratory and field asphalt samples. A long-term pavement performance monitoring of the control and test sections will be performed after the initial performance evaluation phase for determining the ultimate benefits of the increased density asphalt pavements.
