Stone Matrix Asphalt
Mix draindown is usually combated by adding cellulose or mineral fibers to keep the asphalt binder in place. Cellulose fibers are typically shredded newspapers and magazines, while mineral fibers are spun from molten rock. A laboratory test is run during mix design to ensure the mix is not subject to excessive draindown.
