This study investigated the documentation of proof rolling requirements for the 50 United States. A search of the Department of Transportation website for each state was conducted and data compiled. A field observation was conducted using a 31,000 lb water truck to roll over Class 4 Decomposed Granite that was compacted to 95% according to sand cone and nuclear densometer testing. Analysis was also conducted to document the percent increase in area and volume of coverage when proof rolling is used in addition to sand cone or nuclear testing. Literature relating to proof rolling, earthwork, and compaction was reviewed to contribute to the results of this study. It was concluded from the observed analysis that proof rolling using pneumatic tired vehicles is a sufficient check for compaction. It was also concluded that the lack of literature and standard procedures for proof rolling has created requirements specifying various equipment, loads, and methods to be followed to satisfy compaction requirements.
