Abstract Environmental problems caused by waste tires are becoming increasingly prominent. There is an urgent need to find a green way to dispose of waste tires, and scholars have made considerable efforts in this regard. In the construction industry, rubber extracted from waste tires can be added to concrete to alleviate environmental problems to a certain extent. As a new building material, rubber concrete has superior properties compared to ordinary concrete and has been widely used in many fields. Numerous studies have been conducted worldwide to investigate the effect of waste tire rubber on the performance… More >

Abstract In recent decades, the utilization of waste tires, plastic and artificial shale ceramsite as alternative fine aggregate to make self-compacting concrete (SCC) has been recognized as an eco-friendly and sustainable method to manufacture renewable construction materials. In this study, three kinds of recycled aggregates: recycled tire rubber particles, wood-plastic particles, artificial shale ceramsite were used to replace the sand by different volume (5%, 10%, 20% and 30%), and their effects on the fresh and hardened properties of SCC were investigated. The slump flow and V-funnel tests were conducted to evaluate the fresh properties of modified-SCC… More >

Abstract 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 [Ferretti and Bignozzi (2012)]. 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 More >

Abstract In this study, the results of an in-situ experimental program on the performance of concrete taxiways are presented. 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 instrumented with strain gauges embedded in concrete for the acquisition of vertical strains. The results of the experimentation are discussed in view of possible applications to the computational analysis of the stress field induced into pavements by aircrafts. More >
