Standard Test Method for the Effect of Fuel on Asphalt Mixtures

Importancia y uso:

5.1 This test method can be used to test asphalt mixtures in conjunction with mixture design testing to determine the potential for fuel spill damage. This assessment is particularly important for airfield pavements that are subject to fuel spills where fuel damage could lead to surface degradation and the generation of foreign object debris (FOD). This test method can also be used to evaluate and design asphalt mixtures used in other pavement applications that frequently suffer from oil and fuel spill distresses (for example, bus lanes, truck stops, fueling centers).

5.2 This test method is used to measure the fuel resistance of asphalt mixtures through FML as a result of fuel conditioning. Because damage to asphalt mixtures may present itself in forms that do not result in a direct loss of material (for example, reduction in adhesion quality between aggregate and asphalt binder), some specifying agencies may also wish to determine mechanical properties of fuel-conditioned mixtures. Appendix X1 and Appendix X2 provide information on how to modify Test Methods D4867/D4867M and D6931 to measure TSR_f or AASHTO T 401 to measure CML.

Note 1: The quality of the results produced by this standard is dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
