Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Characterize all of the research fine and coarse aggregates used in pavement research at Turner-Fairbank Highway Research Center (TFHRC) for concrete, asphalt, and granular base layers. Create an accessible database for use by all pavement researchers at TFHRC.
Goals:  
The objective is to characterize all of the research fine and coarse aggregates used in pavement research at Turner-Fairbank Highway Research Center (TFHRC) for concrete, asphalt, and granular base layers. Contractor and Federal personnel calibrated the Aggregate Imaging System (AIMS) II equipment and run shape, angularity, and texture scans on all the available research fine and coarse aggregates at TFHRC. 
 
Develop an accessible database for use by all pavement researchers at TFHRC.
Background Information:   The Aggregate Imaging System (AIMS) II equipment is the product of the Federal Highway Association's (FHWA) Highways for Life interlaboratory study of precision by a number of highway materials laboratories.
Field Test:   Federal Highway Association's (FHWA's) Highways for Life interlaboratory study of precision by a number of highway materials laboratories.
