The Use of Phosphoric Acid to Stiffen Asphalt Binders
Accepted in:
Course Highlights
This online engineering PDH interactive presentation focuses on offering guidelines for the use of phosphoric acid to stiffen asphalt binders for hot mix paving applications.
This course presents data on the likely effect on pavement life, moisture resistance, and use with limestone aggregates and liquid amine antistrip additives. Analytical methods for the detection of phosphoric acid in asphalt binders are also presented. Asphalt producers, hot-mix paving contractors, and State departments of transportation are the main audiences.
The Use of Phosphoric Acid to Stiffen Hot Mix Asphalt Binders provides guidelines for the use of the different commercially available grades of phosphoric acid to enhance the high temperature performance grade of asphalt binders derived from different crude oil sources for use in hot mix paving applications. The expected effect on pavement life, in terms of oxidative aging, moisture resistance, fatigue, rutting, and use with different types of aggregates are presented. Analytical procedures for detecting the presence of phosphoric acid using X-ray fluorescence spectroscopy as well as a simple rapid test method are included.
This 2 PDH online interactive presentation is designed for civil engineers, transportation engineers, producers of asphalt binders, hot mix paving contractors, State departments of transportation, local highway agencies, and professional engineers responsible for the use of phosphoric acid to stiffen asphalt binders.
