Aero would have been a small factor: peak speed in the coastdown testing was 22 km/h (13.7 mph).

The average speed would have been significantly less (but I didn't measure that).

EDIT: and yes, the ambient temp was probably also going up during the testing. Looks like 1 degree C change, or from 73.4 to 75 F. Though the temp of the asphalt was probably going up faster than the air temp.
