The SMA wheel tracking test is carried out on samples (slabs) prepared in a laboratory or cut out of a pavement. Additional requirements for samples may be determined in the following two ways:
• Requiring a void content in the slab; in this case the requirement has a range of 3% (v/v), (e. g., 3-6% [v/v]).
• Requiring the compaction factor; in this instance a requirement with a range of 2% (e. g., 98-100%) should be imposed.
All the aforementioned requirements actually specify the quality of the prepared sample (slab) before testing.
14.5.10 Reaction to Fire
When an SMA mix has to meet requirements for resistance against fire specified in other regulations, this property should be tested and classified according to the method described in EN 13501-1.
