Abstract

Twelve construction projects were sampled at the plant, from the spreader box, after spreading, and after compacting. Laboratory tests including gradation analysis, ball-mill wear tests, Atterberg limits, and specific gravity were performed to determine changes in gradations. Kentucky limestones are very hard, high quality aggregates, with no significant degradation characteristics under current construction practices. On a given project, the construction procedure did not cause any significant degradation. Amongst projects, variances can be significant; however, this is attributable to the variation in initial gradations on the different projects.
