Statistical Modeling of Hydraulic and Mechanical Properties of Pervious Concrete Using Nondestructive Tests
Because of its lower mechanical properties and durability compared to normal concrete, pervious concrete demands better quality control and greater inspection efforts to remain functional. Nondestructive tests (NDTs), ultrasonic pulse velocity (UPV) in particular, were used to increase the effectiveness of the quality assurance of pervious pavements. Predictive models for hydraulic conductivity (main feature) and compressive strength (main concern) of pervious specimens were derived using only UPV combined with total void ratio. The results confirm that UPV offers a technique for rapid assessment of in-place properties of pervious concrete, either to supplement or replace core testing in some cases. Combined use of UPV and void ratio was found to outperform the models based on a single test result. Based on the obtained results, statistical models were put forward for predictions of pervious concrete’s hydraulic conductivity and compressive strength.
