This document 1 contains 13 papers that address pavement assets under performance-based contracts; using performance targets and budget constraints to identify optimal highway asset maintenance; a cross-asset resource allocation framework for achieving performance sustainability; public opinions of roadway assets; and, performance-based maintenance methods to improve Virginia highways. This issue also explores the development of an enhanced Alaska pavement preservation program and strategy selection guide; prioritizing infrastructure maintenance and rehabilitation activities under various budgetary scenarios; chip seal adhesion performance with modified binders in cold climates; the effects of curing and oxidative aging on raveling in emulsion chip seals; and, asphalt emulsion sprayability and drain-out characteristics in chip seals. Additionally, this issue examines methods for a fog seal field test with polymer-modified emulsions; a joint resealing project at Fairchild Air Force Base, Washington; and, corrosion by chloride deicers on highway maintenance equipment. |
