New Test Method for Effect of Fuel on Asphalt Mixtures
1. Scope
This test method covers the procedures for conditioning asphalt mixtures in fuel and measuring their resistance to fuel degradation. The method describes the determination of specimen mass loss due to fuel immersion (FML) using cylindrical laboratory-prepared asphalt mixture specimens. The test output FML can be used to evaluate the effect of fuel exposure on asphalt mixtures. Fuel-conditioned mixtures may be further evaluated for mechanical properties; the measurement of fuel-related tensile strength ratio (TSRf) and Cantabro mass loss (CML) will be described in Appendixes.
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 acceptable particle loss by mass after fuel immersion (FML) 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. The purpose of this proposed standard is to (1) develop a standardized test method for agencies to reference for specifying fuel resistant mixtures and (2) standardize the determination of the effects of fuel.
The title and scope are in draft form and are under development within this ASTM Committee.
