Title: Design of High Modulus- High Binder Asphalt Layers
Contact: Brian K. Diefenderfer
Project No.: 75397
Target Date: 12/31/2006
Abstract: High modulus-high binder asphalt (HMHBA) layers are used successfully in Europe. They are used to provide long lasting pavements (perpetual pavements). Perpetual pavements have HMHBA bottom and intermediate layers that resist cracking and deformation and therefore last a long time. The top layer is replaced as needed but lasts a long time because of the support of the lower layers. The life cost for perpetual pavements should be much less than for other asphalt pavements. Designs for HMHBA layers need to be developed to allow for the construction of perpetual pavements.
