The samples that will be evaluated have been exposed to field conditions as well as indoor and outdoor laboratory conditions. Evaluate CRRs to identify which types of materials, exposure conditions, and geometries have shown corrosion initiation. In addition, quantify the extent of the corrosion identified. Obtain chloride profiles from in-service bridges constructed with CRR. The evaluation will include analysis of all available data that has been collected over the lifetime of the samples as well as collecting new data as appropriate.]]> Mon, 03 Jun 2024 14:22:14 GMT https://rip.trb.org/View/2384731 Pavement Marking Selection for Bridge and Pavement Preservation Treatments https://rip.trb.org/View/2381745 Wed, 22 May 2024 14:30:23 GMT https://rip.trb.org/View/2381745 Method for Using ISPEs in Crash-Testing Protocols https://rip.trb.org/View/2381712 Tue, 21 May 2024 15:29:37 GMT https://rip.trb.org/View/2381712 Developing a Data Repository to Help with TSMO Strategies Evaluations https://rip.trb.org/View/2381698 Mon, 20 May 2024 21:18:05 GMT https://rip.trb.org/View/2381698 Managing the Life Cycle of Software for Evolving Traffic Management Systems https://rip.trb.org/View/2381709 Mon, 20 May 2024 19:54:07 GMT https://rip.trb.org/View/2381709 Evaluations of FHWA Research & Technology Program Projects.
