Performance-related Specifications for Emulsified Asphaltic Binders Used in Preservation Surface Treatments

Download or read book Performance-related Specifications for Emulsified Asphaltic Binders Used in Preservation Surface Treatments written by Y. Richard Kim and published by . This book was released on 2017 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research report presents recommended emulsion performance grade (EPG) specifications for asphalt emulsions used in three pavement preservation surface treatments (PSTs): chip seal, microsurfacing, and spray seals. These EPG specifications are climate-driven and applicable to traffic loads that are anticipated during the service life of each PST. The report also presents recommended test protocols for evaluating some of the properties of binders for which test methods are not readily available. The information contained in the report will guide materials and maintenance engineers in evaluating, selecting, and specifying the binders for use in PSTs that will provide acceptable performance and service life. The information contained in the report will be of immediate interest to materials and maintenance engineers and others involved in specifying and evaluating materials intended for use in PSTs.
