    The objective of this investigation is to environmentally evaluate three concrete design methods through a Life Cycle Assessment using the methodology of the Institute of Environmental Sciences (CML), from Leiden University, ...
  • Differences in cracking resistance of asphalt mixtures due to ageing and moisture damage 

    López Montero, Teresa; Miró Recasens, José Rodrigo (2016-06)
    Article
    Accés restringit per política de l'editorial
    The ageing phenomenon and moisture damage become key factors to evaluate mixture cracking resistance. In this paper, the effect of ageing and water on cracking resistance and fatigue behavior in a bituminous mixture is ...
  • Estudio del uso de ligantes modificados en mezclas antifisuras 

    Pérez, Ignacio; Pérez, Vicente; García, Antonio; Pérez Jiménez, Félix Edmundo; Miró Recasens, José Rodrigo; Botella Nieto, Ramón (2016-04)
    Article
    Accés obert
    La fisuración es uno de los deterioros más habituales en firmes de hormigón o mezclas bituminosas muy envejecidas o con bases de ligantes hidráulicos. En los firmes flexibles la aparición de este tipo de deterioros viene ...
  • Ultimate bond strength assessment of uncorroded and corroded reinforced recycled aggregate concretes 

    Fernández Pérez, Ignasi; Etxeberria Larrañaga, Miren; Marí Bernat, Antonio Ricardo (2016-05)
    Article
    Accés restringit per política de l'editorial
    This experimental study assesses the bond performance of recycled aggregate concretes (RAC) with embedded uncorroded and corroded steel bars. The RAC were produced using 20%, 50% and 100% of coarse recycled aggregates ...
  • Effect of of ageing and temperature on the fatigue behaviour of bitumens 

    Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Moreno Navarro, Fernando; Rubio Gámez, María del Carmen (2015-12)
    Article
    Accés restringit per política de l'editorial
    Bitumen ageing plays a significant role in determining the resistance of asphalt mixes to fatigue cracking. Regardless of the type of ageing (oxidation during manufacture or during the service life), hardening effects ...
  • Analysis of the thixotropic behavior and the deterioration process of bitumen in fatigue tests 

    Pérez Jiménez, Félix Edmundo; Botella Nieto, Ramón; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée (2015-12)
    Article
    Accés restringit per política de l'editorial
    The characterization of fatigue damage on bituminous materials under cyclic loading has been classically studied using tests and procedures previously developed for the characterization of metallic materials. However, these ...
  • The influence of temperature on the fatigue behaviour of bituminous materials for pavement rehabilitation 

    Moreno Navarro, Fernando; Rubio Gámez, María del Carmen; Miró Recasens, José Rodrigo; Pérez Jiménez, Félix Edmundo (2015-05)
    Article
    Accés obert
    The rehabilitation of deteriorated pavements has become one of the main concerns in road engineering. Thus, the development of more resistant bituminous mixtures to be used as surface layers is a priority for the sector. ...
  • Evaluation of the GPR frequency spectra in asphalt pavement assessment 

    Pedret Rodés, Josep; Pérez Gracia, María de la Vega; Martínez Reguero, Adriana Haydée (2015-10)
    Article
    Accés obert
    Ground penetrating radar (GPR) is frequently used in pavement assessments, mainly using the evaluation of wave travel times. However, GPR data provide further information that could be used in order to determine the inner ...
  • Assessment of the adhesive capacity of asphalt binders in the aggregate-binder bonds by means of new methodology 

    Valdés Vidal, Gonzalo A.; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée (2015)
    Article
    Accés obert
    The main goal of this study is to present a new methodology to characterize the adhesive capacity (cohesion and adhesion capacity) of asphalt binders by means of new mechanical parameters. This methodology is based on the ...
  • Rheology of fresh concretes with recycled aggregates 

    Faleschini, Flora; Jiménez Fernández, Cristian Gonzalo; Barra Bizinotto, Marilda; Aponte Hernández, Diego Fernando; Vázquez Ramonich, Enric; Pellegrino, Carlo (2014-12-30)
    Article
    Accés restringit per política de l'editorial
    The most frequently used measure of rheology is the slump test, which evaluates workability. Since this value is often operator-sensitive, a more quantitative estimate can be derived in terms of fundamental physical ...
