Utility Cut Repair Techniques— Investigation of Improved Cut Repair Techniques to Reduce Settlement in Repaired Areas, December 2005

Pavement settlement occurring in and around utility cuts is a common problem, resulting in uneven pavement surfaces, annoyance to drivers, and ultimately, further maintenance. A survey of municipal authorities and field and laboratory investigations were conducted to identify the factors contributing to the settlement of utility cut restorations in pavement sections. Survey responses were received from seven cities across Iowa and indicate that utility cut restorations often last less than two years. Observations made during site inspections showed that backfill material varies from one city to another, backfill lift thickness often exceeds 12 inches, and the backfill material is often placed at bulking moisture contents with no Quality control/Quality Assurance. Laboratory investigation of the backfill materials indicate that at the field moisture contents encountered, the backfill materials have collapse potentials up to 35%. Falling Weight Deflectometer (FWD) deflection data and elevation shots indicate that the maximum deflection in the pavement occurs in the area around the utility cut restoration. The FWD data indicate a zone of influence around the perimeter of the restoration extending two to three feet beyond the trench perimeter. The research team proposes moisture control, the use of 65% relative density in a granular fill, and removing and compacting the native material near the ground surface around the trench. Test sections with geogrid reinforcement were also incorporated. The performance of inspected and proposed utility cuts needs to be monitored for at least two more years.

The Amish Mennonites: A sketch of Their Origin, and of Their Settlement in Iowa, with Their Creed in an Appendix,1894.

Traces the origin and growth of the Mennonite movement from its first summation into a creed in Holland and its story as it has been recorded in American, and in later years in Iowa.

Settlement At Culverts, May 1984

Research project HR-219 was sponsored by the Iowa Highway Research Board and the Iowa Department of Transportation. The funding authorized from the Primary Road Research Fund was $11,200. The author wishes to express his appreciation to Iowa DOT personnel for their participation in the research. The special features were incorporated into the plans by Road Design personnel. Office of Materials personnel developed the proportions for the flowable mortar. Project inspection was provided by the Creston Resident Engineer and his staff. The excellent cooperation of the contractors contributed to the success of the research. The prime contractor was Irving F. Jensen Company, Inc. of Sioux City, Iowa who retained Reilly Construction Company of Ossian, Iowa and GNA Concrete, Inc. of Grimes, Iowa as subcontractors for the special culvert backfilling.

Investigation of Improved Utility Cut Repair Techniques to Reduce Settlement in Repaired Areas, Phase II, TR-566, 2010

Trench maintenance problems are caused by improper backfill placement and construction procedures. This report is part of a multiphase research project that aims to improve long-term performance of utility cut restoration trenches. The goal of this research is to improve pavement patch life and reduce maintenance of the repaired areas. The objectives were to use field-testing data, laboratory-testing data, and long-term monitoring (elevation survey and falling weight deflectometer testing) to suggest and modify recommendations from Phase I and to identify the principles of trench subsurface settlement and load distribution in utility cut restoration areas by using instrumented trenches. The objectives were accomplished by monitoring local agency utility construction from Phase I, constructing and monitoring the recommended trenches from Phase I, and instrumenting trenches to monitor changes in temperature, pressure, moisture content, and settlement as a function of time to determine the influences of seasonal changes on the utility cut performance.
