Technical observations are presented on certain emulsified asphalt treated mixes (ETM) used as treated bases and surface treatment in the Arizona/New Mexico area of the Southwest. ETM's fit well within the restrictive factors related to energy and ecoloy; other cost advantages are also discussed. Minimal attention to control in the production of aggregates leads to inevitable problems in subsequent mix application; improved inspection is needed. The observation is made that current sand equivalent design minima may prove conservative, and work with marginal aggregates is reported. Work has been done in arid areas without use of mix water for dispersal of emulsion binder. The core drill has been used in some projects and diametral resilient modulus observations have provided field substantiation of anticipated changes in the stiffness of the pavement. The importance of observing aged pavement stiffness, and improved voids/voids filled relationship is poninted out. Observations are also made regarding open-graded aggregates, and the isolation of ETM's in the treated base field.
