Rubber Modified Asphalt Concrete (Metro RUMAC) Evaluation of Lakeview Junction and Pacific Highway Author(s): Miller, Bo Origin: Oregon Date: September 1995 Categories: Performance Key Words: Pavement, asphalt, admixtures, rubber, ground tires Summary: This report covers the construction in 1992 of test sections on two projects asphalt concrete modified with tire rubber. One project’s test sections are part of a single lift overlay on a lightly traveled two-lane road south of Klamath Falls, Oregon. The other project’s test sections are part of the base course of a three-lift overlay on a heavily traveled four- lane divided highway between Eugene and Springfield. All test sections use a dense-graded rubber modified asphalt concrete developed for the METRO agency of the Portland, Oregon urban area. Control sections were paved with conventional asphalt concrete adjacent to the test sections. The test sections are compared to these control sections.
