The development of distress prediction models for overlaid flexible main street pavements in large municipalities cross Saudi Arabia is described. The sigmoid of models represented quantitatively predict distress density versus pavement age and are based on pavement condition data maintained by the General Directorate of Operation and Maintenance (GDOM) at the Municipality of Riyadh city, Jeddah city, Makkah holy city, Madinah city, and Damam city. Different model forms of the sigmoid family were examined in an attempt to identify the most appropriate one for fitting the data. Models are available for the following distress types in flexible main street pavements: Block Cracks, Longitudinal and Transverse Cracking, Patching, Potholes, Depressions, Weathering and Raveling, and Cracking (due to patching). The seven models have been developed using more than 11 years survey data for overlaid sections on the road network of Riyadh, Jeddah, Makkah, Madinah, and Damam. In all prediction models, age is by far the most significant predictor of deterioration. The traffic volume in terms of Annual Daily Traffic (ADT) and the drainage play only a secondary role in forecasting prediction of distress propagation. In general, the developed models provided an
