  • Evaluating the role of aggregate gradation on cracking performance of asphalt concrete for thin overlays 

    García Gil, Lívia; Miró Recasens, José Rodrigo; Pérez Jiménez, Félix Edmundo (Multidisciplinary Digital Publishing Institute, 2019-02)
    Article
    Accés obert
    Thin asphalt concrete overlays are a maintenance technique that mainly restore the functional properties of pavements. One of the main issues in thin overlays is reflective cracking that can cause early deterioration and ...
  • DUSST: development of a new stress sweep fatigue test for asphalt mixtures 

    Valdés Vidal, Gonzalo A.; Botella Nieto, Ramón; Pérez Jiménez, Félix Edmundo; Calabi, Alejandra; Sánchez Aloso, Elsa (Elsevier, 2018-12)
    Article
    Accés restringit per política de l'editorial
    Fatigue cracking is one of the main damage mechanisms that take place in asphalt pavements. However, its evaluation during the design asphalt mixtures is not usually considered due to the complexity of the tests required, ...
  • Effect of nanomaterials on ageing and moisture damage using the indirect tensile strength test 

    López Montero, Teresa; Crucho, João; Picado-Santos, Luís; Miró Recasens, José Rodrigo (2018-04)
    Article
    Accés restringit per política de l'editorial
    Environmental conditions as well as traffic loads lead to the deterioration of asphalt pavements during their service life. For this reason, the use of nanomaterials that improve the mixtures behaviour could be interesting. ...
  • New approach to characterize cracking resistance of asphalt binders 

    García Gil, Lívia; Miró Recasens, José Rodrigo; Pérez Jiménez, Félix Edmundo (2018-03)
    Article
    Accés restringit per política de l'editorial
    Asphalt binder characterization is a complex and difficult task due to its rheological behaviour. Indeed it has been traditionally realized by means of simple tests at an established temperature. An added challenge is that ...
  • Effect of the recycling process and binder type on bituminous mixtures with 100% reclaimed asphalt pavement 

    Nosetti, R.A.; Pérez Madrigal, Domingo; Pérez Jiménez, Félix Edmundo; Martínez Reguero, Adriana Haydée (2018-04)
    Article
    Accés restringit per política de l'editorial
    There is a great interest in increasing the amount of recycled material used in asphalt mixes because of the beneficial impact on the environment. This is leading to the development of different recycling procedures, from ...
  • Analysis of cracking resistance of bituminous mixtures under monotonic and cyclic loads 

    Pérez Jiménez, Félix Edmundo; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Botella Nieto, Ramón (2017-11)
    Article
    Accés restringit per política de l'editorial
    Although cracking resistance is one of the most important properties affecting the durability of asphalt mixtures, this property is often not considered as a requirement in the mixture design stage, and the bitumen content ...
  • Self-heating and other reversible phenomena in cyclic testing of bituminous materials 

    Botella Nieto, Ramón; Pérez Jiménez, Félix Edmundo; Riahi, Ebrahim; López Montero, Teresa; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée (2017-12)
    Article
    Accés restringit per política de l'editorial
    This paper's objective is to evaluate the reversible phenomena that take place when asphalt materials are subjected to cyclic loads, i.e., self-heating and thixotropy. A strain sweep test was adapted to capture the stiffness ...
  • Ageing and temperature effect on the fatigue performance of bituminous mixtures 

    López Montero, Teresa; Miró Recasens, José Rodrigo (Instituto Técnico de la Construcción y del Cemento, 2017-07)
    Article
    Accés obert
    The ageing of asphalt mixes, together with their exposure to low temperatures, causes a progressive increase of cracking. In this paper, the effect of ageing and temperature on the fatigue of asphalt concretes made with ...
  • Asphalt toughness effect on bituminous mixture fatigue behavior 

    Noguera, Alfredo H.; Miró Recasens, José Rodrigo (Pontificia Universidad Católica de Chile, 2011-08)
    Article
    Accés obert
    One of the most important parameters to define bituminous mixture behavior in service is the toughness that the bitumen provides when binding the aggregate particles; that is; the dissipated energy during the materials ...
  • Modelling self-heating and thixotropy phenomena under the cyclic loading of asphalt 

    Riahi, Ebrahim; Allou, Fatima; Botella Nieto, Ramón; Tehrani, Fateh Fakhari; Dubois, Frederic; Absi, Joseph; Petit, Christophe; Pérez Jiménez, Félix Edmundo (2017-05)
    Article
    Accés obert
    Asphalt concrete is a heterogeneous material containing a viscoelastic bituminous matrix and elastic aggregates. When testing asphalt materials under cyclic loading, various phenomena (so-called biasing effects) can decrease ...
  • Effect of mixing time and temperature on cracking resistance of bituminous mixtures containing reclaimed asphalt pavement material 

    Pérez Madrigal, Domingo; Iannone, Andrea; Martínez Reguero, Adriana Haydée; Giustozzi, Filippo (2017-08)
    Article
    Accés obert
    The use of reclaimed asphalt pavement (RAP) in bituminous mixtures is considerably increasing due to the environmental and economic benefits of recycled materials. However, stiffer mixes, usually resulting from RAP addition, ...
  • Obtaining the fatigue laws of bituminous mixtures from a strain sweep test: effect of temperature and aging 

    López Montero, Teresa; Miró Recasens, José Rodrigo; Botella Nieto, Ramón; Pérez Jiménez, Félix Edmundo (2017-07)
    Article
    Accés restringit per política de l'editorial
    Fatigue is associated with the deterioration caused by applying repeated loads, and is affected by temperature or aging. Generally, time sweep tests are used to simulate fatigue, in order to obtain the fatigue laws. However, ...
