Pavement condition data is an essential component of any Pavement Management System (PMS). The general purposes of pavement condition data collection and evaluation are to determine the existing pavement condition at the time of inspection, to establish the immediate pavement maintenance needs and to plan for future needs. Riyadh city, capital of the Kingdom of Saudi Arabia, is in the process of developing Pavement Maintenance Management System (PMMS) for the city street network. Pavement data collection and evaluation is one of the system’s main components. Pavement condition included structural capacity, roughness, visual condition survey and skid resistance. Structural capacity data was determined using a Dynatest Falling Weight Deflectometer (FWD). Roughness measurements were collected using May’s Ride Meter (MRM). Visual condition survey involved developing a distress evaluation form. The form included type, density and severity of the common type of distress found in the network. Skid resistance measurements were collected using Mu meter. The main objectives of this paper are to describe the procedures used to collect pavement condition data and to evaluate the pavement condition data of the city main street network. In general the paper presents the experience of the Riyadh city in collecting and evaluating pavement condition data. The analysis indicated that pavement condition of the city is in good and acceptable condition. However, more attention should be directed to improve skid resistance of the pavement network.
