Title:

Portland Cement Concrete Pavement Thickness and Shear Wave Velocity Variation Versus Observed Pavement Distresses

Accession Number:

Record Type:

Component

Abstract:

Concrete slab thickness is the key characteristic of a concrete pavement. It is the most important design parameter and the major focus of control and inspection during construction. It is widely accepted that thickness deficiencies can reduce performance. In order to investigate possible correlations between Portland cement concrete (PCC) with observed surface distresses, a combination of nondestructive ultrasonic thickness tests and distress surveys was performed in three existing highways prior to their rehabilitation. In addition to concrete thickness, concrete shear wave velocity was also measured in ultrasonic tests. Construction records were also reviewed. An in-depth statistical analysis was performed in order to investigate possible thickness/distress or velocity/distress relations using various predictors. While the results discussed here are limited by the small number of analyzed sections, they illustrate the importance of material quality and uniformity control during construction, since alterations in material properties significantly influenced pavement performance.
