This study presents three bitumen modifiers which may find successful application in the fabrication of binders for warm mix asphalt in the paving industry. In that sense, two non-polymeric additives, thiourea and thiourea ... -
Computational Design Applied to Equilibrium-Staged and Rate-Based Absorption Processes
Román, Claudia; Delgado Canto, Miguel Ángel; Lazar, Liliana; García Morales, Moisés (Revista de Chimie, 2020-08)
Simulators are of great interest in Chemical Engineering because they facilitate process optimization and help evaluate different solutions through the so-called “what-if” approach. They include the most advanced ... -
The development of polyurethane modified bitumen emulsions for cold mix applications
Carrera Páez, Virginia; Cuadri Vega, Antonio Abad; García Morales, Moisés; Partal López, Pedro (Springer Verlag, 2015)
Bitumen emulsions stand for an alternative paving practice to the traditional hot-mix asphalts. In addition, modified bitumen emulsions show a better performance than unmodified ones. This work studies the feasibility of ... -
Effect of transesterification degree and post-treatment on the in-service performance of NCO-functionalized vegetable oil bituminous products
Cuadri Vega, Antonio Abad; García Morales, Moisés; Navarro Domínguez, Francisco Javier; Partal López, Pedro (Elsevier, 2014)
The bitumen modification through polyurethane prepolymers presents significant benefits for the manufacture of bituminous products for the paving industry. In this sense, this work explores the use, as bitumen modifier, ... -
Effective integration of computational tools into Chemical Engineering studies at an international level
Román, Claudia; Delgado Canto, Miguel Ángel; Lemos, Francisco; García Morales, Moisés (Universitat Politècnica de València, 2020-04)
Current Higher Education students have grown up in a society characterized by the massive use of information technologies, which affects the way they expect to acquire new knowledge. In Chemical Engineering studies, ... -
Electro-active control of the viscous flow and tribological performance of ecolubricants based on phyllosilicate clay minerals and castor oil
García Morales, Moisés; Fernández Silva, Samuel D.; Roman, Claudia; Delgado Canto, Miguel Ángel (Elsevier, 2020-11)
Lubricating fluids with highly improved tribological performance very often entail the use of environmentally disrespectful formulations. Based on organoclay dispersions in castor oil, the present research explores the ... -
End-performance evaluation of thiourea-modified bituminous binders through viscous flow and linear viscoelasticy testing
Cuadri Vega, Antonio Abad; García Morales, Moisés; Navarro Domínguez, Francisco Javier; Airey, Gordon; Partal López, Pedro (Spinger Verlag, 2013)
Straight-run bitumens are no longer suitable in new asphalt mixtures. Consequently, the use of modified bitumens has become more important. In order to both improve binders mechanical properties and prevent it from phase ... -
Enhancing the viscoelastic properties of bituminous binders via thiourea-modification
Cuadri Vega, Antonio Abad; García Morales, Moisés; Navarro Domínguez, Francisco Javier; Partal López, Pedro (Elsevier, 2012)
Although added in a very low concentration, bitumen controls the final properties and performance of the resulting asphalt mixture. As an alternative to classic bitumen modification with polymers, we herein propose the use ... -
Exploring the effect of the pulp bleaching on the thermo-rheological behavior of sustainable cellulose nanofiber-based oleogels
Roman, Claudia; Delgado Canto, Miguel Ángel; Fernández Silva, Samuel David; García Morales, Moisés (Elsevier, 2022-09-17)
