Abstract: One of the main objectives of the Caltrans Long Life Pavement Rehabilitation Strategies for rigid pavements (LLPRS-Rigid) is to have a construction productivity of approximately 6 lane-kilometers within a 55-hour construction window. This productivity objective must not conflict with the other two main LLPRS-Rigid objectives: to provide 30 plus years of pavement service life and to minimize pavement maintenance. This report describes the processes and results of a constructibility and productivity analysis for the Caltrans LLPRS-Rigid project, focusing on optimizing the maximum production capability within a 55-hour weekend closure. The analyses explored the effect of the following parameters on the concrete pavement construction productivity in California: pavement design profile, curing time, number and capacity of resources, number of lanes to pave, type of construction scheduling, and alternative lane closure tactics. The typical construction processes for concrete pavement rehabilitation were modeled with input from California concrete paving contractors, Caltrans, and academia.
