Pavement Marking Retroreflectivity Inspection Data: A Weibull Analysis

摘要: Quantifiable life-cycle models of the service life pavement markings are essential for a cost-efficient marking management system. A study was conducted to develop an analysis procedure typical retroreflectivity inspection data. Retroreflectivity data collected by National Transportation Product Evaluation Program on water-based paints in 2002 Pennsylvania test deck were used. Those considered interval-level duration data, and Weibull performed. is method reliability engineering which scale shape parameters estimated from failure making objective maintenance decisions. Results indicated that had 1.42 (±0.05), 601.67 (±17.73) days, respectively, skip line areas 2.38 (±0.08) 227.41 (±4.48) left wheelpath areas. It also determined probability 2-year wat...
