Relationship Between Joint Spacing and Distresses Present

Previous research by Parsons and Hall has shown that joint spacing in Portland cement concrete (PCC) airfield pavements has an effect on pavement deterioration rates and life cycle costs. The purpose of this study was to investigate how the differences in pavement performance for various joint spacing lengths (slab sizes) are manifested in the individual distresses used to measure pavement condition. Specifically, this study investigates if the poorer performance in pavements with larger joint spacing is related to a difference in the types, amounts, or severities of distresses present as compared to pavements with smaller joint spacing. The hypotheses investigated in this study were: (1) Smaller slabs perform better because they have fewer overall distresses. (2) Smaller slabs perform better because they have lower overall severities. (3) Smaller slabs perform better because they have fewer “high-deduct” distresses.
