  • Influence of Road Wetness on Tire-Pavement Rolling Resistance
    Journal of Civil Engineering and Architecture 9 (2015) 1302-1310 doi: 10.17265/1934-7359/2015.11.004 D DAVID PUBLISHING Influence of Road Wetness on Tire-Pavement Rolling Resistance Jerzy Ejsmont1, Leif Sjögren2, Beata Świeczko-Żurek1 and Grzegorz Ronowski1 1. Technical University of Gdańsk (TUG), Mechanical Faculty, Gdańsk 80 233, Poland 2. Swedish National Road and Transport Research Institute (VTI), Linköping 581 95, Sweden Abstract: Rolling resistance of tires is one of the most important factors influencing energy consumption of road vehicles, especially on rural roads. For practical reasons, most of rolling resistance measurements are usually performed for dry road conditions. Based on the fact that roads are wet during a considerable time over the year and as part of the projects MIRIAM, ROLRES and ROSANNE, the TUG (Technical University of Gdańsk) in Poland and VTI (Swedish National Road and Transport Research Institute) in Sweden carried out trailer rolling resistance measurements on wet road surfaces to investigate water film influence on rolling resistance on different pavements. A specially-designed trailer to measure rolling resistance has been used. The test sections were both rural roads and an abandoned airfield equipped with water film sensors mounted in the pavement. Results indicate strong influence of test speed and water film depth, as well as influence of surface texture. The increase of rolling resistance on wet surfaces is caused by both hydrodynamic phenomena and cooling effect of water that decreases tire temperature thus increasing rolling resistance. Key words: Tires, rolling resistance, road wetness, water film. 1. Introduction parameter is precipitation. Considering road construction, the drainage performance and the Rolling resistance is one of the most important pavement design (material and structure) are the most functional properties of road pavements.

For more information about the projects program at WPI, please see http://www.wpi.edu/Academics/Project i Abstract Thailand’s National Science and Technology Development Agency is seeking to develop a successful program to manage approximately 600,000 tonnes of waste tires generated annually in Thailand. This project investigated Thailand-specific issues and options for a viable long-term waste tire management strategy. We evaluated current practices, potential technologies, and successful systems from foreign nations to draw conclusions and make recommendations regarding which technologies are most applicable to Thailand. We made additional recommendations concerning which aspects of a waste tire management system needed to be newly implemented or continued to be used and improved.

  • Devulcanization Technologies for Recycling of Tire-Derived Rubber: a Review
    materials Review Devulcanization Technologies for Recycling of Tire-Derived Rubber: A Review Erich Markl and Maximilian Lackner * University of Applied Sciences FH Technikum Wien, A-1200 Vienna, Austria; [email protected] * Correspondence: [email protected] Received: 20 January 2020; Accepted: 2 March 2020; Published: 10 March 2020 Abstract: In general, composite materials are difficult to recycle. Tires belong to this class of materials. On top, one of their main constitutents, vulcanized rubber, is as elastomer, which cannot be remolten and hence is particularly challenging to put to a new use. Today, the main end-of-life routes of tires and other rubber products are landfilling, incineration in e.g., cement plants, and grinding to a fine powder, generating huge quantities and indicating a lack of sustainable recycling of this valuable material. True feedstock recycling is not feasible for complex mixtures such as tires, but devulcanization can be done to reactivate the cross-linked polymer for material recycling in novel rubber products. Devulcanization, i.e., the breaking up of sulfur bonds by chemical, thermophysical, or biological means, is a promising route that has been investigated for more than 50 years. This review article presents an update on the state-of-the art in rubber devulcanization. The article addresses established devulcanization technologies and novel processes described in the scientific and patent literatures. On the one hand, tires have become high-tech products, where the simultaneous improvement of wet traction, rolling resistance, and abrasion resistance (the so-called “magic triangle”) is hard to achieve. On the other hand, recycling and sustainable end-of-life uses are becoming more and more important.

  • Resource Responsible Use of Recycled Tire Rubber in Asphalt Pavements
    Resource Responsible Use of Recycled Tire Rubber in Asphalt Pavements PUBLICATION NO. FHWA-HIF-20-043 April 2020 FOREWORD Pneumatic tires are designed to fulfill fundamental functions throughout their useful lives like cushioning, damping, transmitting of torque (driving and braking), dimensional stability, abrasion resistance, efficient rolling resistance, and durability. Lacking the ability to recycle old tires into new tires, there are several common repurposing methods to effectively reuse rubber. Recycling of rubber from old tires may include but is not limited to: tire-derived fuel, ground tire rubber, and civil engineering applications. GTR is the second highest consumer of recycled tire rubber. This informational brief provides a review and update on the various GTR processes used in production of asphalt pavements. It presents the most recent waste tire data along with a historical perspective of GTR use as a modifier for asphalt binders and as an additive in asphalt mixtures. Consideration for responsible use of GTR is given to promote sustainable use of GTR in asphalt pavements. Additional detailed information can be obtained from Federal Highway Administration (FHWA) publication FHWA-HIF-14-015 on The Use of Recycled Tire Rubber to Modify Asphalt Binder and Mixtures. The FHWA has an ongoing Accelerated Implementation and Deployment of Pavement Technologies (AIDPT) Program, which includes the deployment of innovative technologies to improve pavement performance and reduce agency risk. This report was prepared under Development and Deployment of Innovative Asphalt Pavement Technologies Cooperative Agreement with the University of Nevada, Reno. Notice This document is disseminated under the sponsorship of the U.S. Department of Transportation (USDOT) in the interest of information exchange.

  • Functionalization of Crumb Rubber Surface for the Incorporation Into Asphalt Layers of Reduced Stiffness: an Overview of Existing Treatment Approaches
    recycling Review Functionalization of Crumb Rubber Surface for the Incorporation into Asphalt Layers of Reduced Stiffness: An Overview of Existing Treatment Approaches Christina Makoundou 1,* , Kenth Johansson 2, Viveca Wallqvist 2 and Cesare Sangiorgi 1 1 Department of Civil, Chemical, Environmental and Materials Engineering, University of Bologna, 40131 Bologna, Italy; [email protected] 2 Department of Material and Surface Design, Research Institutes of Sweden (RISE), 114 28 Stockholm, Sweden; [email protected] (K.J.); [email protected] (V.W.) * Correspondence: [email protected]; Tel.: +39-05-1209-0215 Abstract: The substitution of mineral aggregates with crumb rubber (CR) from waste end-of-life tires (ELTs) in the asphalt concretes, has been considered a sustainable paving industry approach. The rubber has been used to construct pavements with proven enhanced resilience and improved durability. However, some issues related to the rubber’s surface adhesion or swelling may arise with these practices and generate complications (binder consumption, temperatures, mixing times). One possible solution to overcome the materials’ compatibility problems is to pre-treat the CR’s surface before its incorporation into the asphalt mixes to allow a surface functionalization that can enhance coverage and cohesion inside the mixes. The physical treatments using radiations-based beam are already exploited in the plastic recycling industries avoiding the use of chemicals in considerable amounts. Such treatments permit the recovering of large quantities of polymer-based materials and the enhancement of interfacial properties. This article provides an overview of existing Citation: Makoundou, C.; Johansson, surface treatments of polymers and especially rubber, including gamma ray, UV-ozone, microwaves, K.; Wallqvist, V.; Sangiorgi, C.
