Abstract: The Missouri River flooding in 2011 caused significant damage to secondary roadway infrastructure systems in western Iowa. This paper documents results of an investigation designed to evaluate unpaved roads and bridge ...

Abstract: An approach to quantify nonuniformity of compacted earth materials using spatially referenced roller-integrated compaction measurements and geostatistical analysis is discussed. Measurements from two detailed case studies ...

Abstract: Compaction control for pavement foundations typically consists of determining the optimum water content and maximum dry unit weight from a Proctor test, and then specifies an acceptable water content and dry unit weight ...

Abstract: This paper documents recent experiences using roller-integrated compaction monitoring (RICM) technologies on hot-mix asphalt (HMA) overlay construction projects in Iowa. Recently, new special provisions (SPs) to specifications ...
