New Test Method for Effect of Fuel on Asphalt Mixtures
1. Scope
This test method covers the procedures for preparing, conditioning, and testing laboratory-prepared asphalt mixture specimens for resistance to degradation by fuel immersion. The test method describes the determination of specimen mass loss due to fuel immersion (FML) as well as mechanical property testing of unconditioned and fuel-conditioned specimens with the primary output being fuel-based indirect tensile strength ratio (TSR-f). The test outputs FML and TSR-f can be used to evaluate the effect of fuel exposure on asphalt mixtures.
Keywords
Asphalt mixture; fuel resistant asphalt; fuel resistance; fuel mass loss; fuel-conditioned tensile strength ratio
Rationale
The FAA and DoD have adopted and are utilizing specifications for fuel resistant asphalt that specify the maximum particle loss by mass that is acceptable for a mixture to be considered fuel resistant. The test procedure for determining fuel resistance is currently outlined within the agency specifications themselves rather than referencing a standardized test method. Current agency specifications include provisions for only FML. The purpose of this proposed standard is to (1) develop a standardized test method for agencies to reference as needed in specifying fuel resistant mixtures and (2) standardize the determination of both FML and TSRf in place of FML alone.
The title and scope are in draft form and are under development within this ASTM Committee.
