Pavement renewal for urban highways is a critical issue confronting the California Department of Transportation (Caltrans) as large portions of its highway system have exceeded their original 20-year design lives and are in need of rehabilitation and reconstruction. This paper introduces the innovative pavement renewal technologies and techniques that Caltrans has developed and/or adapted under the "Get In, Get Out, and Stay Out" approach emphasizing a rapid, long-lived renewal of urban highway pavements with minimized traffic impacts. Experimental projects where the effectiveness of these technologies and techniques were validated are discussed. Also introduced in the paper is the integrated analysis process combining pavement design, construction logistics, and traffic operations that Caltrans applied in its latest experimental highway project. CA4PRS (Construction Analysis for Pavement Rehabilitation Strategies) software was used as an analysis tool in the integrated process. Caltrans expects that this integrated analysis process will better ensure the selection of optimum rehabilitation strategies reflecting given project conditions to effectively reduce costs to transportation agencies and highway users. It is expected that the positive results and lessons learned from testing these technologies and techniques on the experimental projects cited will lead to the expanded application of the "Get In, Get Out, and Stay Out" approach in future urban highway rehabilitation projects in California. The issues and outcomes discussed in this paper will be beneficial to other transportation agencies and contractors in maximizing rehabilitation productivity, minimizing agency and user delay costs, and achieving long-life performance in urban highway rehabilitations.
