Constructing Smooth Hot Mix Asphalt Hma Pavements PDF Download

A program has begun in Colorado to prove that HMA pavements can be effectively constructed at intersections and provide significant benefits to the owner. To many highway agencies, performance, construction speed, and cost are the three key issues to consider when rehabilitating or reconstructing high traffic intersections. Therefore, demonstration projects were organized by the Colorado Asphalt Pavement Association (CAPA) to demonstrate performance, construction speed and cost advantages over PCC pavements at high traffic intersections in Colorado. This paper documents the planning, design, and construction processes that were followed to successfully build an HMA pavement at an intersection carrying over 7.7 million 18 kip (8200 kg) ESALs for a 20-year design.
