• Abstract:
  The objective of this project is to use validated intelligent compaction (VIC) technology to map 1/4 to 1/3 of the unpaved gravel road network across the state of Iowa. This work will be done over 2 summer seasons to be completed in the 3-year time frame set forth in the AID Grant NOFO. The mapping will gather Modulus Values; Road Geometry (x,y,z); Surface material type, gradation, moisture control; and Digital photos. Collected data will be analyzed. Modulus values will be calculated. Independent DCP tests will be taken at locations when k-values are less than an identified amount to determine if low k-values are surface or subgrade issues.
