Abstract This recommendation is based on the results of an inter-laboratory study organised by RILEM technical committee TC 264-RAP "Asphalt Pavement Recycling"—Task Group 3 (TG3) focusing Asphalt Binder for Recycled Mixture. The TG3 aimed to evaluate effect a specific family materials known as asphalt recycling agent (ARA) aged binder under different configurations. Even though ageing irreversible phenomenon, effective ARA must have capability improve flexibility bituminous and their...
Despite asphalt self-healing with encapsulated rejuvenators having been intensively researched over the last decade, there is still uncertainty about performance advantages granted by this technology. As a way of adding to existing set research methodologies, study aimed test feasibility visual method investigate working mechanism in bituminous mixture. For purpose, clear mixtures were produced using colorless synthetic binder and pigment was added rejuvenator incorporated calcium alginate...
Bitumen ageing stands for a number of physico-chemical modifications that occur in bitumen as response to environmental conditions. Several tests have been proposed simulate ageing. Two the most common ones are: a) Rolling Thin Film Oven Test (RTFOT), which simulates short term ageing; b) Pressure Ageing Vessel (PAV) test, accounts long-term and it is usually performed on RTFOT residue. A study 50/70 pavement grade caused by presented. Both PAV were used. follow-up due was done several...
Bitumen is the most common binder used in production of bituminous mixtures for road paving, having a fundamental influence on performance pavement. However, it not yet fully understood which bitumen properties have significant behaviour mixtures. In this context, FunDBitS project was developed. Its main objective to prepare recommendations be specified order obtain suitable mixtures, namely what concerns its resistance permanent deformation (rutting), stiffness, low temperature cracking,...
Research on biobinders has been recognized as an essential contribution to achieving the sustainable development goals established by United Nations. The paper aims present ongoing BioRoadPAV® project – New Biobinders for Application Road Pavements that is currently being developed in Portugal from 2021 2023. main objective develop new road obtained bio-oil produced innovative process of thermochemical liquefaction biomass. describes project's activities, laboratory design full-scale...
As part of a project funded by the European Commission (EC) for development and evaluation multiresidue methods analysis drinking related waters, 15 laboratories evaluated method using styrene-divinylbenzene co-polymer solid-phase extraction followed gas chromatography/mass spectrometry. The main aim study was to evaluate whether meets requirements EC Directive 98/83 in terms accuracy, precision, detection limit 22 pesticides according following requirements: detection, < or = 0.025...
Biomass is one the most abundant renewable energy sources, and it can be processed through different thermochemical methods to obtain oils that replace petroleum bitumen used in road construction. For construction industry accept replacement with bio-oil, necessary know its properties determine applicability of conventional testing methods. This research utilized a liquified wood heavy fraction (bio-oil) obtained from waste an innovative liquefaction process. The aim was investigate kind...
