Effects of the mineralogical composition and particle size distribution of ladle furnace slag as a cement/fine aggregate replacement in concrete
(2023-01)
Article
Open AccessLadle furnace slag (LFS) shows excellent potential for valorization. Despite this, landfills are typically its final destination, mainly because of technological barriers in its valorization process. This work examines the ... -
Effect of the use of Marpol waste as a partial replacement of the binder for the manufacture of more sustainable bituminous mixtures
(2022-03)
Article
Open AccessSociety must move towards an economy in which sustainability is its main driving force. A sustainable solution to avoid sending waste to landfill, the consumption of raw materials and, therefore, the depletion of natural ... -
Study of adhesion between steel slag aggregates and bitumen taking into consideration internal factors influencing moisture damage
(2023-02)
Article
Restricted access - publisher's policyElectric arc furnace slag (EAFS) has been proposed as a replacement in hot-mix asphalt. This work compares the physical-chemical-mineralogical and morphological factors involved in the moisture damage of natural aggregates ... -
Sustainable asphalt mixtures by partial replacement of fine aggregates with low-grade magnesium carbonate by-product
(Elsevier, 2023-07)
Article
Open AccessThe utilisation of large quantities of raw materials for asphalt mixtures manufacturing, such as aggregates, is an environmental issue that must be addressed. This concern has led to valorising waste and by-products as ... -
Long-term comparison between waste paper fly ash and traditional binder as hydraulic road binder exposed to sulfate concentrations
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-08)
Article
Open AccessSulfate attack is one of the drawbacks of cementitious materials for stabilized soils. In the current study, a durability comparison of stabilized soil with cement (Type IV) and waste paper fly ash (WPFA) was conducted. ... -
Machine learning techniques to estimate the degree of binder activity of reclaimed asphalt pavement
(2022-05)
Article
Open AccessThis paper describes the development of novel/state-of-art computational framework to accurately predict the degree of binder activity of a reclaimed asphalt pavement sample as a percentage of the indirect tensile strength ... -
On the analysis of uniaxial cyclic strain sweep test results to bituminous binders: stiffness-phase angle curve
(2022-04)
Article
Restricted access - publisher's policyThis paper discusses the analysis of uniaxial tension–compression cyclic strain sweep test results for the characterisation of bituminous materials. The test results of one bitumen and two mastics, at different oxidative ... -
The effect of temperature, rest periods and ageing on the response of bituminous materials in fatigue tests: considerations and proposals on analytical dimensioning model
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02)
Article
Open AccessOne of the basic assumptions of analytical dimensioning models of asphalt pavements is failure due to fatigue cracking of the bituminous layers. Furthermore, it is considered that the damaging effects of different traffic ... -
A new proposal to assess shear fatigue resistance of asphalt pavement interfaces
(2021-05)
Article
Open AccessThe degree of adherence between two bituminous layers can be assessed from shear tests carried out at constant displacement speed, which allow the shear strength and stiffness of the interface to be obtained, being usual ... -
Evaluation of the rejuvenation of asphalt by means of oil-saturated porous aggregates
(2022-02)
Article
Open AccessRoad degradation is an increasing problem for assets managers. Roads deteriorate mainly due to the combination of different factors, such as temperature, climate and traffic loads. This causes the asphalt to age and, ... -
Ladle furnace slag as a partial replacement of Portland cement
(Elsevier, 2021-06)
Article
Restricted access - publisher's policyLadle furnace slag (LFS) has been proposed as partial cement replacement due to its similar chemical composition with Portland cement. However, its mineralogical composition needs to be considered due to problems with ... -
Valoración de emisiones de gases de efecto invernadero de mezclas bituminosas mediante el modelo ECCO2
(2020-07)
Article
Open AccessARNÓ, con la colaboración de la Universidad Politécnica de Cataluña, ha desarrollado una herramienta de cálculo, denominada ECCO2, para estimar los impactos ambientales de mezclas bituminosas producidas con distintos ...
