2012 Iowa Small Hospital Improvement Program (SHIP) Briefing and Survey Report, January 22, 2013

In August of 2012 the Iowa State Office of Rural Health (SORH) conducted a survey to determine the value of the Small Rural Hospital Improvement Program (SHIP) in Iowa. This survey was distributed to the 84 participating hospitals however, because some hospitals network their SHIP funds we only asked the contract administrators of the contracts to complete the survey. 58 of the 78 SHIP contract administrators completed the survey (74%). Background: SHIP brings in roughly $750,000.00 annually to Iowa to assist small Iowa hospitals. Average distribution of approximately $7,500 per hospital. Seventy three of ninety nine Iowa counties are represented.

Evaluation of PCC Long-Term Durability Using Intermediate Sized Gravels to Optimize Mix Gradations, April 2010

With the implementation of the 2000 Q-MC specification, an incentive is provided to produce an optimized gradation to improve placement characteristics. Also, specifications for slip-formed barrier rail have changed to require an optimized gradation. Generally, these optimized gradations have been achieved by blending an intermediate aggregate with the coarse and fine aggregate. The demand for this intermediate aggregate has been satisfied by using crushed limestone chips developed from the crushing of the parent concrete stone. The availability, cost, and physical limitations of crushed limestone chips can be a concern. A viable option in addressing these concerns is the use of gravel as the intermediate aggregate. Unfortunately, gravels of Class 3I durability are limited to a small geographic area in Mississippi river sands north of the Rock River. Class 3 or Class 2 durability gravels are more widely available across the state. The durability classification of gravels is based on the amount and quality of the carbonate fraction of the material. At present, no service histories or research exists to assess the impact of using Class 3 or 2 durability gravels would have on the long-term durability of Portland cement concrete (PCC) pavement requiring Class 3I aggregate.
