Pozzolan Cement Study
This research study was to evaluate the performance of a Type 1P cement concrete pavement constructed on an experimental project as compared to a regular Type 1(B) cement concrete pavement. The sections were evaluated for strength, durability, skid resistance, workability of concrete, finish, ride and deflection. Overall, the Type 1P cement concrete was comparable in quality to the regular Type 1(B) cement concrete. No mixing problems were created, and the Type 1P cement concrete was a more workable mix and easier to finish. Skid resistance and ride results were comparable; however, freeze-thaw durability results on the Type 1P cement concrete fell lower than expected. It was recommended that Type 1P cement be allowed as an alternate for use in all concrete, except for wearing surfaces under traffic in pavements or bridge decks. It was recommended that Type 1P cement be allowed for use in both cast-in-place and precast structural elements with the above mentioned exceptions of bridge decks. Another exception would be that Type 1P cement should not be utilized in soil cement construction at this time. Additional wearability evaluation should be made on pavements for a period of time. Implementation included a specification revision which was approved by the Chief Engineer and are in use now.
