Abstract:

The Kansas Department of Transportation began evaluating individual beds in limestone quarries for suitability for use in concrete pavement in 1980. Aggregates that were suitable for use in Portland Cement Concrete Pavement (PCCP) were designated as Durability Class I Aggregate. By 1986 several quarries had been evaluated and it was decided to construct a project with various Durability Classed Aggregates to prove the system that was used to classify the limestones. Class I Limestone has a 95% probability of providing 20 years of service life before the pavement is rehabilitated due to D-cracking.
