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...
Abstract Since cleaning of artworks may cause undesirable physicochemical alterations and is a nonreversible procedure, it mandatory to adopt the proper procedure. Such procedure should remove undesired materials whilst preserving original surface. In this regard, numerous gels have been developed exploited for various artwork surfaces. Lately, agarose (AG) polyvinyl alcohol-borax (PVA-B) hydrogels widely employed as tools by conservators. Both show some limitations in specific practices....
Bitumen characterisation and differentiation usually involve a combination of mechanical chemical analyses. However, these methods provide limited information on the diversity caused by binders' origin or processing method. Thus, question arises whether bitumen microstructure can be used to identify issues. In this study, microscopic methods, including brightfield, darkfield fluorescence optical inverse microscopy (OIM), as well confocal laser scanning (CLSM) atomic force (AFM), were...
The multiple stress creep-recovery (MSCR) test was recently introduced to evaluate bituminous binders at high service temperatures, in particular the or loading resistance. This allows classifying high-performance graded temperature, according traffic loading, starting from standard, heavy, very heavy and extreme loading. It is intention that this includes nonlinear binder properties. In study, five laboratories have participated a round robin repeatability reproducibility of parameters...
This paper investigates the low temperature rheological properties of bitumen using a dynamic shear rheometer with 4 mm parallel plates (4-mm DSR). Different procedures sample preparation were tested and evaluated. For comparison, measurements also carried out bending beam (BBR). Test results show that 4-mm DSR can perform at very temperatures (down below −30 °C). With this geometry, little amount is required. There are certain statistical correlations between complex modulus measured by...
ABSTRACT The morphology of bitumen-SBS blends is studied using Epi-Fluorescence microscopy. Morphology defined as the partition polymer-rich and bitumen-rich phases. Existing sample preparation methods for microscopy on bitumen are compared obtained morphologies shown. In a second part, differences in related to rheological behavior. morphological properties strongly depend temperature, where taken, upon cooling rate isothermal annealing periods. During storage can undergo major changes....
Oxidative ageing in field asphalt pavements is a complex process with coupled multiple physics. This parametric study uses Multiphysics modelling approaches to evaluate the effects of material thermal properties, air voids content and distribution, mastic coating thickness, oxygen accessibility binder oxidative kinetics on spatial temporal evolution pavements. Results suggest that increasing conductivity layers leads lower gradient. The variations base subgrade layers' properties cause...
It is well documented that most bituminous binders contain crystallisable material. This fraction, often referred to as paraffinic or natural wax, associated with the bitumen’s origin and has an influence on its rheological performance. In literature, Differential Scanning Calorimetry (DSC) primary technique used determine melting crystallisation behaviour of this waxy fraction. However, in bitumen, thermal transitions DSC are typically very broad can be combined recrystallisation effects...
Moisture susceptibility is still one of the primary causes distress in flexible pavements, reducing pavements’ durability. A very large number tests are available to evaluate a binder aggregate combination. Tests can be conducted on asphalt mixture, either loose or compacted form, individual components an pavement. Apart from various mechanisms and models, fundamental concepts have been proposed calculate thermodynamic tendency combination adhere and/or debond under wet conditions. The aim...
