IPERs has three membership classes. Each class has different contribution rates and benefits. Most IPERS members are in the regular class. Only sheriffs, deputy sheriffs, and those working in protection occupations are not. (Protection occupations include certain employees of the Department of Corrections, state and county conservation peace officers, city police officers, DOT peace officers, airport firefighters, airport safety officers, fire prevention inspector peace officers, regular and volunteer firefighters, air base security officers, county jailers, emergency medical service providers, county attorney investigators, and National Guard installation security officers.)

Per legislative requirement, attached is the Iowa Department of Transportation’s summary of project status for infrastructure projects that have been appropriated revenue from various funds including Rebuild Iowa Infrastructure, Health Restricted Capitals, Bridge Safety, Revenue Bonds Capitals, and Revenue Bonds Capitals II. Although a status report for the Bridge Safety Fund was already submitted to the directors of LSA and DOM, a status report on those projects is also included within this attachment for consistency with last year’s reporting. In addition, per request from LSA, status reports for the FY 2011 passenger rail appropriation from the Underground Storage Tank Fund and the FY 2010 Commercial Service Vertical Infrastructure appropriation from the General Fund are also listed in this report.

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.
