S.T.A.T.E. Testing Advances Hot Mix Testing Technology

One of the more recent technological developments comes in the form of a testing device to extract asphalt binder from hot-mix asphalt (HMA) mixes and automatically separate the components for analysis. Rather than devoting days to traditional reflex extraction to determine binder content from an HMA sample, or relying on ignition ovens and correction factors, technicians at S.T.A.T.E. Testing LLC, Dundee, Illinois, use a new piece of equipment to accomplish the task more quickly. The Asphalt Analyzer manufactured by infraTest USA, Walpole, Massachusetts, avoids technician exposure to highly flammable and dangerous solvents such as trichloroethylene and can provide results in about 90 minutes.

Iowa DOT Report: Evaluation of the infraTest Asphalt Analyzer for Performing Extractions on Recycled Asphalt Materials Final Report for MLR-17-01: 


Eight RAP samples with binder contents from 3.4 percent to 6.0 percent were selected from samples submitted for Iowa projects in 2016. They were split to do comparative and repeat-ability testing. Five splits of each of the eight RAP samples were run in the Asphalt Analyzer with Trichloroethylene (TCE) as the solvent. One split was tested according to the current modified AASHTO T164 with N-Propyl Bromide (NPB) as the solvent.
