Pervious concrete pavement (PCP) has the potential to provide significant sustainability benefits. To understand better the significance of PCP, its performance should be evaluated comprehensively throughout its service life. Because PCP performance has not been investigated thoroughly, no condition indices have been developed for it. This paper aims to develop an overall combined condition index to investigate PCP performance. To develop the index, a specific panel rating method and field performance investigations were conducted. The panel subjectively evaluated surface conditions and permeability rates of various PCP sections. The field investigations involved objective measurements of surface conditions and permeability rates of the same PCP sections. It is not practical to conduct a panel rating for PCP condition evaluation in the future; conducting field investigations (objective assessments) is more practical and cost-effective. Thus, regression analyses were applied to relate objective surface condition measures to subjective surface condition ratings. After objective surface condition measures were evaluated, subjective surface condition ratings were computed using the regression relationship. Permeability rates were combined with subjective surface condition ratings using adequate weighting factors to obtain the overall combined condition index.
