    The suitability of asphalt emulsions for upgrading marginal aggregates has been evaluated. The aggregates tested included a high quality basalt, two low quality marine basalts, and a fine grained dune sand. Mix properties evaluated included diametral resilient modulus and diametral fatigue life for both as-compacted specimens and specimens conditioned by moisture exposure. Layered elastic design principles were used with the dynamic test results to develop layer equivalencies for emulsion treated marginal aggregates compared with hot mix asphalt concrete. The results indicate that beneficiation of marginal aggregate with asphalt emulsions should make acceptable paving mixes, particularly for low volume roads.
