PERSONS FATALLY INJURED IN MOTOR VEHICLE CRASHES - 2001 1/, FUNCTIONAL SYSTEM Pavement Condition Information on pavement conditions was obtained from State of the Pavement, 2002; Interstate and Primary Highways. Published by Central Office Pavement Management Staff, June 2002. In the mid-1990s VDOT began to collect pavement distress data through the use of videotaped images. To make use of data collected from those tapes VDOT also made interim use of the pavement condition index (PCI) defined and used by the U.S. Army Corps of Engineers. After several trial years, the PCI was deemed too general for Virginia conditions so that a VDOT specific method, as described in detail in Appendix A, was considered necessary. Briefly, that system recognizes that pavement distresses fall into two basic categories; they are either load related (caused by the application of vehicular loadings) or they are not load related (caused by the exposure of pavement elements to the environment). This realization gave rise to the development of two indices to describe pavement surface distresses. These are the load related distress rating (LDR) and the non-load related distress rating (NDR). These two indices, also, use 0 to 100 scales and are the basis for pavement surface condition evaluation in VDOT. The advent of pavement data collection through contracted automated means led to a need for standardization of procedures for the purposes of consistency and as a contractual instrument for bidding purposes. The document providing this standardization, A Guide To Evaluating Pavement Distress Through The Use Of Video Images , was developed in the late 1990s and made available to vendors bidding on contract data collection. To bring all pavement management elements into one computerized system, the Virginia Highway Pavement Management Application (HPMA) has been under development since the mid 1990s and now is well into implementation. The emphasis at this time is on final software testing, conversion of the data to the formats required by the new software, personnel hiring and training, development of standards and specifications, and the institution of quality assurance activities. However, the program already provides useful products. Pavement condition information is one such product. Dissemination of that product throughout the agency is a major reason a 1998 condition report and the present report were assembled. One of the uses of this information is to aid in the day-to-day maintenance activities of the agency. Another value of disseminating this information is to receive feedback from users on the PMP and its implementation. That feedback will be used to identify and address changes that may enhance the continued successful PMP implementation. Exhibit R38 : Pavement Condition Definition
