Abstract:

This report outlines the development and implementation phase of chip seal performance specification for Oregon. Two chip seal workshops were held to involve chip seal stakeholders including a variety of Oregon Department of Transportation (ODOT) personnel and contractors. A voluntary survey about the potential specification changes was developed and results are presented. A series of specification meetings were held with ODOT and industry to re-evaluate the specification and potential changes line-by-line. The specifications developed as a result of the specification meetings are presented and specification guidance is provided. Flow charts were developed aid in specification processes and action items. Chip seal design and a design spreadsheet are discussed. Finally, the Oregon DOT conducted a demonstration project under the new specification. The details and results of the demonstration project are presented.
