<br />1.Verify the finding of Wood and Cole (2013) that high air voids is the primary cause of <br />stripping <br />2.Investigate why high air voids occurred for locations where observed <br />3.Identify mix design or construction practices that may have led to observed stripping. <br />Upon completion of the first phase work, the project objectives were to develop and/or suggest <br />practices to address stripping. Possible practices discussed with LRRB prior to the project work included <br />maintenance techniques to extend the life of chip seals that have failed in stripping; best practices to <br />prevent stripping in Minnesota pavements; and specification, mix design, and construction guidelines <br />for low-volume residential streets if current mix designs are susceptible to failure in stripping <br />1.3 OVERVIEW OF REPORT <br />This report documents the full research effort (including data), which included field testing/evaluation <br />and material collection at 18 locations in eight Minnesota municipalities and laboratory testing of <br />collected materials. The report discusses (A) the results of field and laboratory tests and (B) an analysis <br />of collected data. Finally, the report provides recommendations based on testing and analysis. <br /> <br />3 <br /> <br />
