Abstract:
As a result of the need for a rapid test method for use in predicting long-term in situ strength from short-term nondestructive test measurements, a study was undertaken to evaluate various dynamic test procedures and to recommend a preferred nondestructive test procedure for predicting long-term strength. Based on test data, pulse velocity as a predictor of compressive strength was selected as the preferred nondestructive method among those evaluated. While the prediction of 28- and 90-day compressive strength from 1 or 2 day pulse velocity measurements is feasible, the prediction depends on compositional factors such as air content and aggregate type. Further research on the use of I- and 2-day pulse velocity as a predictor of long-term compressive strength is suggested in this paper. Such pulse velocity measurements could be used in conjunction with accelerated test methods for a comprehensive evaluation of in situ strength.
