Hot Mix Asphalt CTTP 97-014

This course requires the use of the nuclear density gauge; each participant must show evidence of having attended a radiation safety course, and provide their own radiation dosimeter; failure to do so will result in the person being ineligible for the course.

Classes commence at 1:00 p.m. on Wednesday and ends at 5:00 p.m. on Friday.

This course covers sampling and testing of hot-mix asphalt, to include volumetric analysis of compacted specimens (Marshal and Superpave), asphalt content by nuclear gauge, and in-place density with the nuclear density gauge. The procedures covered are those prescribed by the Arkansas State Highway and Transportation Department (AHTD) Standard Specifications for Highway Construction (2003 Edition), to include the following.
