Abstract
In order to expand the applications of pervious concrete, additional research and testing must be done into its structural performance. Distress surveys were performed on two field installations of pervious concrete subjected to equivalent stresses as a "Collector" street in use for approximately 20 years. The results of the distress survey were then used to calculate the Pavement Condition Index (PCI) using the procedure from ASTM D 6433 (2007). The PCI rating was considered to be a quantification of structural performance. The high PCI ratings of the thicker pervious concrete sections indicated that pervious concrete, when properly designed, is capable of being used for most "Residential" streets and many "Collector" streets for typical design life durations (20-30 years) while exhibiting satisfactory structural performance. Currently, there is no accepted thickness design method for pervious concrete pavements. This thesis evaluates the two most commonly used concrete thickness design methods, AASHTO (1993) and PCA (1984), for their applicability to pervious concrete. The observed performance of a pervious concrete field installation was used to assess each thickness design method for use with pervious concrete. Both methods yielded results having a higher variation for pervious concrete than for regular concrete. The lower percent of thicknesses under designed and closer correlation between actual and predicted thicknesses of the AASTHO (1993) method implies that this may be the preferred method for the design of pervious concrete pavements. However, since both models showed a very poor goodness-of-fit to actual thicknesses, additional research into alternative thickness design methods or the creation of a new thickness design method may be needed.
