STUDY OF BITUMINOUS SURFACE TREATMENTS IN VIRGINIA. PHASE II - SUMMER 1964. DISTRIBUTION CHARACTERISTICS OF MATERIALS EFFECTIVENESS OF ONE SIZE AGGREGATE SETTING TIME. REPORT FOR SUMMER 1965

Ten bituminous distributors and ten chip spreading operations were investigated, the former by cotton pad, cup, and trough tests; the latter by measuring the distance covered by a truckload by placing pans in the road to catch the stone. A wide variation was found in the coverage consistency of the distributors and the aggregate distribution was found to vary between types of spreaders used. Seven one size stone test sections were placed on portions of regularly scheduled surface treatment projects. Insufficient time has passed to permit final evaluation of the test sections. A centrifuge test fashioned after one used in California was used to evaluate lab and field treatments for aggregate whip off. From the results of this empirical test, it is believed that AP-00 asphalt is traffic ready in a much shorter period of time than are cutbacks and emulsions.
