ABSTRACT

The primary objective of this study is to evaluate the structural condition of existing rubblized concrete pavements across Iowa and to develop a knowledge database for rubblization, which will be useful in the selection of cost-effective PCC pavement rehabilitation strategies in Iowa. Seven representative rubblized concrete pavement sections across Iowa were selected for evaluation considering state wide location and pavement age. A series of field experiments were carried out at the selected test sections during 2007. The methodology and the results of data analysis are discussed in this paper highlighting the important findings regarding the long-term performance of Iowa rubblized concrete pavements.
