Abstract

Deterioration of Egyptian desert roads in Upper Egypt (Al-Minea area) were investigated through developing deterioration model. This model requires collecting data related to time periods for different progressive deterioration stages for road surfaces. Ten road segments located in desert roads were studied. Each road segment has an average length of 500 meters. The progressive deterioration stages of road surface were monitored for each segment in term of Pavement Condition Index (PCI) and plotted against time for each road type. Least square regression analysis has shown that a quadratic function represents the best fit for the collected deterioration data with a coefficient of determination (R2) ranges from 0.95 to 0.96. The developed deterioration prediction model can be used to predict future deterioration of desert roads.
