METHODS OF MODIFICATION. Another advantage of using SBR Latex Polymers as an asphalt modifier is that they can be added to any stage of the paving chain – from the refinery to the on-site job location. Major changes in technique are not required.

WebThe UTBWC process consists of a heavy spray application of polymer modified asphalt emulsion followed immediately by an ultra-thin gap-graded hot mix asphalt. Both applications are quick completed in one pass by a specially designed paving machine. Once the hot mixed asphalt is placed, a 10-ton steel wheeled vibratory roller is used for … WebJun 23, 2024 · 11. OPEN GRADED FRICTION COURSE (OGFC) The term OGFC is defined as thin, permeable layer of asphalt that incorporates a skeleton of aggregate size with minimum fines. OGFC depends on the aggregate interlock for its stability. Open-graded friction course (OGFC) is a porous mix, mainly characterized by high air void content (12 … Webpavements and reducing raveling in open-graded friction courses.
