• Abstract:
  In the summer of 1996, the Mississippi Department of Transportation (MDOT) initiated a field trial (MDOT ; State Study No. 111) and a laboratory study (MDOT State Study No. 123) to evaluate the use of polymer ; modified asphalts in hot mix asphalt pavements. In the field trial, nine experimental sections were compared. ; Eight of the sections contain different polymer modification, including four styrene-butadiene copolymers, ; one polyethylene, two crumb rubbers, and a gelled asphalt. A ninth section containing no modifiers serves as ; the control section for the experiment. This experiment was constructed on a section of Interstate 55 ; Northbound near Grenada, Ms. that is subjected to approximately one million Equivalent Single Axle ; Loadings (ESALs) per year. Each section is one half mile in length and is separated from the next section by ; a one half mile long non-modified section. ; Contained within this report is the summary of activities related to MS State Study No. 141, which examines ; the long-term performance of the nine sections. As part of State Study No. 141, an effort has been made to ; characterize the performance of each of the sections by utilizing MDOT’s Pavement Condition Rating (PCR) ; which was developed in conjunction with MDOT’s Pavement Management System.
