Abstract
Problems of material size variance and existence of multiple and sometimes conflicting managerial objectives in asphaltic aggregate mixing are considered. A chance constrained goal programming model is presented which seeks satisfaction of cost minimization as well as other goals. The model considered in this study demonstrates the added cost of satisfying gradation specifications at a given confidence level. While added cost is undesirable, the probabilistic solution will accomplish aggregate blending objectives, while deterministic solutions not considering variance will not.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
