NCAT highlight video
The research center and test track at Auburn University's National Center for Asphalt Technology help make NCAT one of the world's leading institutions for asphalt pavement research and an important source of information for advancing asphalt pavement technology. This video highlights pavement engineering and asphalt research at NCAT, including materials and field testing and forensic analysis.
National best practices on HMA recycling
In-place recycling and reclamation of asphalt pavements helps highway agencies optimize the value of in-place materials, minimize construction time and traffic flow disruptions, and reduce the number of construction vehicles moving in and out of the construction area.
The Transportation Research Board has published NCHRP Synthesis 421: Recycling and Reclamation of Asphalt Pavements Using In-Place Methods, which examines national best practices in the use of hot in-place recycling, cold in-place recycling, and full-depth reclamation of asphalt pavements.
Guidance from APA: Alternate bidding white paper
The Asphalt Pavement Alliance recently published a new white paper, Keys to a Successful Alternate Bidding Process. The free publication outlines procedures set up by FHWA and covers the factors considered in alternate bids, such as initial cost, construction time, and future costs. Also discussed are discount rates, performance periods, rehabilitation plans, salvage value, analysis periods, and more.
