|Project Description:||The analysis method for antistrip additives will utilize thermogravimetric analysis and Fourier Transform Infrared (FTIR) spectroscopy to identify the type of liquid antistrip and the amount present in asphalt binders. X-ray fluorescence analysis will be used to detect and measure the amount of recycled engine oil residue present in asphalt binders.|
|Start Date:||November 1, 2011|
|End Date:||December 31, 2014|
One objective is to develop a test method to rapidly and accurately characterize and quantify the presence of liquid antistrip additives in asphalt binders.
The second objective is to develop a quantitative test method for the analysis of asphalt binders for waste engine oil residues.
|Test Methodology:||Use of Thermogravimetric Analysis and Fourier Transform Infrared (FTIR) spectroscopy.|
|Expected Benefits:||The ability to detect and measure the amount of antistrip additive that has been added to the asphalt will maximize the resistance of the pavement to water, and thereby extend pavement life.|
|Deliverables:||Name: Test Method|
Product Type(s): Research report, Draft standard, specifications, or guidelines
Description: The deliverable is a test method for the analysis of amine antistrip additives in asphalt binders.
