EVALUATION OF THE PAVEMENT CONDITION INDEX FOR USE ON POROUS FRICTION SURFACES
This report documents the results of a field study conducted to evaluate the use of the Pavement Condition Index (PCI) on porous friction surfaces (PFS). Pavements at seven landing field installations using PFS were studied. Results showed that the major problems on this type of surface were: (1) deterioration of underlying asphalt concrete material due to stripping of the asphalt binder; (2) delamination due to loss of bond between the PFS and underlying layer and (3) raveling/weathering due primarily to jet blast. Based on the findings of this study, several modifications were recommended for incorporation into current procedures for evaluating and managing PFS pavements: (1) Modify severity-level definitions for longitudinal/transverse cracks and for raveling/weathering; (2) Rate low severity dense-graded patches as medium-severity; (3) Use a surface treatment of asphaltic material if permeability loss is more than half the original; (4) Develop a nondestructive test to locate areas of delamination; (5) Modify the PCI of older PFS pavements carefully to document when failures occur; and (6) Collect all available PCI and construction date information for PFS pavement and use it to develop a PCT Time Chart.
