Crumb rubber (CR) usage in asphalt pavement sector is an environmentally friendly and economical solution. However, the production temperatures are significantly higher than the traditional mixtures. Thus, the focus of this study is to use Warm Mix Asphalt (WMA) additives in dry process CR modified mixtures to overcome high temperature needs without compromising the performance. Effect of WMA additive on conditioning time, mixing and compaction temperatures, and also rutting and cracking potentials were investigated by experiments. As a conclusion, the compaction temperature could be lowered by 15 degrees C and WMA additive can be used as compaction aid to lower the compaction effort.

Investigation of Moisture Dissipation in Foam-Based Warm Mix Asphalt Using Synchrotron-Based X-Ray Microtomography
Kutay, M. Emin; Öztürk, Hande Işık (American Society of Civil Engineers (ASCE), 2012-06-04)
Foam-based Warm Mix Asphalt (WMA) technologies decrease the viscosity of the asphalt so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and temperature drops. During the process of dissipation of foam, depending on the environmental conditions, the moisture may not escape and may be trapped inside the mixture. This trapped moisture can cause detrimental failures by breaking the adhesive bonds between the aggregates and the asphalt bind...
Laboratory production of calcium sulfoaluminate cements with high industrial waste content
Canbek, Ogulcan; Shakouri, Sahra; Erdoğan, Sinan Turhan (Elsevier BV, 2020-02-01)
A drawback of conventional calcium sulfoaluminate (CSA) cement production is the use of the costly raw material bauxite as a source of alumina to form the main clinker phase ye'elimite. Replacement of bauxite with industrial wastes can benefit CSA cements economically and environmentally. This study demonstrates the use of high amounts of red mud, a sulfate-rich/high-lime fly ash, and desulfogypsum as raw materials in producing CSA clinkers and cements with better mechanical performances than an all-natural...
Strength and fracture properties of roller compacted concrete (RCC) prepared by an in-situ compaction procedure
ŞENGÜN, EMİN; Aleessa Alam, Burhan; Shabani, R.; Yaman, İsmail Özgür (Elsevier BV, 2020-01-01)
© 2020 Elsevier LtdThe use of roller compacted concrete (RCC) technology in pavement applications has been steadily increasing owing to its economical as well as practical advantages. Past literature studies on RCC mixtures, focused mainly on the effects of RCC mixtures on their strength and durability properties, and there is a lack in the fracture properties. In this experimental study, a total of seven different RCC mixtures were designed with four different binder ratios ranging from 200 kg/m3 to 600 kg...
Evaluation of Top Flange Bracing Systems for Curved Box Girders
Topkaya, Cem; Williamson, Eric B. (American Society of Civil Engineers (ASCE), 2005-11-01)
In recent years, steel trapezoidal box girders for curved highway interchanges have become popular. For these bridge systems, significant steel girder cross-sectional stresses occur during the concrete casting sequence. To help resist construction loads, a lateral truss system is installed at a level close to the top flanges to form a "pseudo-closed" section, which has a higher torsional stiffness than an open U-section. Several recent incidents, ranging from the buckling of individual bracing members to th...
Properties of blended cements with thermally activated kaolin
Arikan, Metin; Sobolev, Konstantin; Ertuen, Tomris; Yeginobali, Asim; Turker, Pelin (Elsevier BV, 2009-01-01)
Kaolin, one of the materials of major importance for the ceramic and paper industry, is also used in the construction industry as a raw material for the production of white cement clinker and, in the form of metakaolin, as an artificial pozzolanic additive for concrete. Metakaolin is a vital component of high-performance and architectural concrete; however, its application in regular concrete is very limited due to relatively high production costs. This report evaluates the performance of a low-cost metakao...
