Using various maps and graphs, this presentation will detail the significant growth in the U.S. priced managed lane sector in terms of mileage, locations, and toll revenue. The location of priced managed lanes currently under construction will also be included to show anticipated growth over the next several years. Some emerging trends and considerations for the future will be discussed based on involve-ment in recent studies of priced managed lanes around the country.

Longitudinal joints are high in air voids due to compaction limitations. Lowering the void content of these areas improves the durability of the pavement. Project data indicate that rapid penetrating emulsion (RPE) fills the voids beneath the surface of the pavement, reducing air and water intrusion while maintaining surface texture, whereas traditional emulsions seal the surface only. Lab tests have been developed to quantify the penetrating ability of an emulsion and resistance to water exposure. Join us for a discussion.
