Effect of Elevation on Rolling Thin Film Oven Aging of Asphalt Binders

There is concern that aging in the RTFO may be affected by the elevation of the laboratory where the test is conducted. This is important since many asphalts are produced at refineries at low elevations but are sold into markets at higher elevations. Therefore, it is possible the owner-agencies testing these asphalts may get different test results if elevation affects physical properties after RTFO aging.
