Title
Asphalt Pavement Analyzer (APA) Evaluation
Abstract
This report considers the Asphalt Pavement Analyzer (APA) as a tool for evaluating the rutting susceptibility of Minnesota Hot Mix Asphalt (HMA). Its authors analyze the 25 responses to a questionnaire sent to members of the APA Users' Group and conduct a literature review. Based on this evidence, they recommend that Mn/DOT purchase an APA. The tool provides a measure of rutting susceptibility; is reasonably reliable and repeatable; and has been used by over 60 agencies and contractors. In addition, procedures for conducting tests are available in ASTM and AASHTO formats and the Users' Group provides a forum for discussion and support.
