From the Asphalt Pavement Association (APA) this month is the following article entitled "Intersections: Asphalt Does Them Better."  Included in the article is a link to the APA publication entitled "High Performance Intersections" which is extremely informative and can be used to help explain to owners why they should be building their intersections with asphalt pavements.

Intersections: Asphalt Does Them Better
Heavy trucks that are stopping, turning, accelerating or climbing expose pavements to high levels of stress. A new technical publication from the Asphalt Pavement Alliance, High-Performance Intersections, provides useful guidelines to the pavement designers who deal with the challenges of intersections and other high-stress pavements. The publication is available as a free download by clicking here .

"All engineers know that heavy, slow-moving traffic found at intersections, toll booths and other such locations can expose pavements to the highest stress levels possible," explained Wayne Jones of the Asphalt Institute, one of the authors of the document. "But a well-designed, well-constructed pavement at these locations can deliver the same outstanding performance as all other asphalt pavements."

High-Performance Intersections lays out a four-point strategy to ensure good performance for intersections and other high-stress applications. To illustrate the principles, the publication chronicles two head-to-head competitions between asphalt and concrete intersections. It also discusses the "World’s Strongest Intersection," located next to a quarry in Illinois.
