    In response to Federal Aid requirements (23 CFR 637B, October 5, 1995) regarding certification of roadway technicians for quality control/quality assurance (QC/QA) testing, the Arkansas State Highway and Transportation Department (AHTD) sponsored the development of the Center for Training Transportation Professionals (CTTP) at the University of Arkansas, Fayetteville. Training and certification programs executed by CTTP include Hot-Mix Asphalt Field Technician (HMAC Tech) among others. Prerequisite to the HMAC Tech program is a training course in aggregates. The HMAC Tech program includes instruction and testing (written and performance) in the areas of sampling, gyratory compaction, volumetric analysis, asphalt content, and field density. As of November 1, 1998 eight HMAC Tech courses have been completed with a total of 150 persons attending, including 67 AHTD and 83 contractor employees. Of the 150 persons attending, 10 were unsuccessful, for a 93.3 percent pass rate. Student evaluations and anecdotal evidence indicate the program to be a resounding success
