AASHTO HSCOM has received the project deliverables.
The AASHTO Subcommittee on Materials (SOM) maintains the Standard Specifications for Transportation Materials and Methods of Sampling and Testing (Materials Book) that covers over 400 Testing procedures and materials related specifications. Test methods termed “C” specifications are in a format that makes it difficult for technicians to follow the test, as reference is made to a cover letter that may alter portions of the tests. These “C” specifications need an overall review as it is anticipated that many are in need of revisions and updating to current practice. Also, “C” specifications cannot be provided through the AASHTO Electronic Bookstore due to their current formatting, requiring AASHTO customers to go elsewhere for these specifications.
The objective of this research was to review the “C” specifications in the SOM Materials Book, identify needed technical and editorial changes, revise the specifications as required, and present the revised specifications in AASHTO standard format and supporting commentary to the AASHTO SOM for approval.
