DATA OBTAINED FROM TESTS ARE PRESENTED ON ROCK SAMPLES TAKEN IN A SURVEY OF ACTIVE QUARRIES FURNISHING CARBONATE AGGREGATES FOR CONCRETE USED BY THE VIRGINIA DEPARTMENT OF HIGHWAYS. THE PRIMARY OBJECTIVES OF THE SURVEY WERE TO DETERMINE' /A/ THE FREQUENCY OF OCCURRENCE AND VOLUME OF REACTIVE CARBONATE AGGREGATES BEING PRODUCED IN VIRGINIA, /B/ THE GEOGRAPHIC AND STRATIGRAPHIC DISTRIBUTION OF THIS MATERIAL, /C/ THE LITHOLOGIC CHARACTERISTICS OF THE EXPANSIVE ROCKS, AND /D/ ANY CORRELATIONS WHICH MIGHT EXIST BETWEEN MINERALOGIC COMPOSITION AND EXPANSIVE OR OTHER REACTIVE BEHAVIOR. INVESTIGATIONS OF THE SAMPLES INCLUDED MEASUREMENT OF SUSCEPTIBILITY TO ALKALI REACTION BY THE PRISM TEST, FORMATION OF RIMS IN MORTARS AS DISCUSSED BY BISQUE AND LEMISH, DETERMINATION OF CARBONATE MINERALOGY AND INSOLUBLE RESIDUE, AND STUDIES OF THIN SECTIONS. LIMITED SAMPLES WERE GATHERED FROM A LARGE NUMBER OF QUARRIES. REFERENCES' ALKALI REACTIVITY OF CARBONATE ROCKS-EXPANSION AND DEDOLOMITIZATION, D.W. HADLEY, PROC. HRB, 40, 1961.
