Waste Tire Rubberized Concrete Plates for Airport Pavements: Stress and Strain Profiles in Time and Space Domains

The present study follows a previous study on the stress and strain profiles along the cross-section of waste tire rubberized concrete plates for airport pavements, subjected to quasi-static loads. Further results on the in-situ performance of concrete plain and rubberized taxiways have been collected and presented here. The experimental program has been undertaken at the Guglielmo Marconi airport of Bologna (Italy). It concerns two portions of the taxiway, one built with plain concrete and one with rubberized concrete. Each portion has been fitted with strain gauges embedded in concrete for the acquisition of vertical strains.
