Use of Foamed Asphalt Base Reclamation on Local Roads.

Status:  Complete
Report Date:  02/12/2009

Summary:

Investigators gathered and recorded information about the best practices, construction techniques, mix design, specifications and performance of foamed asphalt recycled pavement, and used this information to develop preliminary design guidelines and specifications for the use of foamed asphalt in Minnesota. An evaluation of existing Minnesota projects showed that pavement layers recycled using foamed asphalt develop a uniform strength, and that the foamed asphalt formed a cohesive matrix when mixed with reclaimed material.
