Mineral filler, fine-grained mineral particles naturally present in or manufactured and added to aggregates play a significant role on the performance of asphalt mastic mixtures. A clear understanding effects filler properties paving mixtures is critical ensure good mixture design its field performance. In this study, basic mainly including physical chemical properties, were first reviewed followed by performances. This review finds that particle size distribution specific surface area are...
As a practical and effective tool for quantitative in-plane deformation measurement of planar surface, two-dimensional digital image correlation (2D DIC) is now widely accepted commonly used in the field experimental mechanics. This paper presents an overview use DIC-based techniques asphalt mixture characterisation reported literature. 2D DIC well suited to analyse materials mechanical properties because their anisotropic heterogeneous nature. Fundamentals are first briefly described....
A laboratory investigation was performed to evaluate the influence of filler type and Rigden fractional voids on fundamental fracture limits asphalt mixtures mastics. Fracture properties 14 different mastics composed by combination 7 fillers 2 binders were evaluated using: a visco-elastic mechanics-based crack growth law for mixtures; Bending Beam rheometer at low temperatures Modified Direct Tension Test intermediate temperatures. Digital Image Correlation System employed detect strain...
Abstract The use of a three-point bending beam (3PB) test was investigated to characterise hot mix asphalt (HMA) cracking behaviour. Fundamental HMA fracture properties, identified as tensile strength and energy density at first fracture, were determined for six different mixtures (two natural four SBS polymer modified) applying the Fracture Mechanics framework. Full-field strain maps obtained from an in-house developed digital image correlation-based method observed better understand crack...
A laboratory investigation was conducted to evaluate the effect of both cross-linked and linear styrene–butadiene–styrene (SBS) modifiers on cracking resistance hot mix asphalt (HMA) mixtures. Five types mixtures composed by same aggregate gradation but different binders were produced in laboratory. The performances evaluated using a viscoelastic fracture mechanics-based model entitled 'HMA Fracture Mechanics'. Crack localisation crack growth investigated performing indirect tensile test...
ABSTRACT A laboratory investigation was conducted to estimate the macroscopic cracking response of Styrene Butadiene (SBS) polymer modified asphalt mixtures by analyzing localized strain distribution within material microstructure. Five composed same aggregate gradation but different SBS binders were produced in laboratory. An in-house developed Digital Image Correlation (DIC)-based system employed obtain 2D full-field maps specimens during tensile loading. Strain distributions observed from...
A laboratory investigation evaluates the potential of using stabilized fly ash from municipal solid waste incinerators (MSWIs) as a filler in asphalt mixtures. Nine mixtures composed same aggregate gradation and three different binders fillers (limestone two ashes) are prepared tested. chemical mineralogical characterizes before after mixing with binders. The behavior mastics at low temperatures is estimated by bending beam rheometer (BBR) test. mixtures' cracking behaviors intermediate...
This paper focuses on performance assessment and size effect evaluation flexural fracture tests performed two-layered reinforced asphalt specimens. A steel net three fiber-glass grids were investigated. Three Point Bending 60 mm tall specimens composed by both leveling (20 mm) wearing (40 layers. The test was two differently-shaped (400x100 beams a 500x500 slabs) not samples. Strain localization damage distribution investigated using an in-house Digital Image Correlation (DIC) System capable...
ABSTRACT This paper reports a research study aimed at providing insight into key mechanisms and mixture properties that influence fracture in asphalt concrete. The experimental analysis was based on the Hot Mix Asphalt (HMA) Fracture Mechanics visco-elastic crack growth law. HMA cracking mechanism investigated using multiple laboratory test configurations both unmodified polymer modified mixtures. A Digital Image Correlation (DIC) employed to more accurately capture localized or non-uniform...
A verification of fracture energy density is presented as a fundamental threshold in hot-mix asphalt. Fracture was evaluated with the semicircular bending (SCB) test. Experimental analyses were enhanced by digital image correlation system capable providing dense and accurate displacement–strain field composite materials at microstructural level suitable for describing cracking behavior crack initiation. The resulting SCB predicted displacement discontinuity method to explicitly model...
The work presented in this paper aims at providing a better understanding of the mechanical response surface layer fibreglass-reinforced flexible pavements. reinforcement technique consists installing fibreglass grid between levelling (placed on base course to seal and level pre-existing distresses) wearing (or overlay). Flexural fracture tests were performed two-layered reinforced asphalt specimens composed both courses simulate real overlay structure. Three grids characterised by different...
Cold recycled bituminous materials can consist of up to 100% reclaimed asphalt pavement (RAP) treated with different binders such as emulsion and foamed bitumen, for Hot recycling the highest percentage is trying be achieved, recent studies suggest 40% a possible RAP in hot mixtures, actually some countries have this their specifications others even more (i.e. Japan). These high percentages make it necessary completely characterise material before proceeding mix design, done all other...
Hydrated lime has been used in hot mix asphalt (HMA) to reduce moisture sensitivity and stripping since 1910 the United States. During past 40 years, researchers from all over world have focused on this topic finding that hydrated can actually provide many other benefits mixtures. In paper, use of a high surface area (HSA) as filler mixtures was investigated assess influence microstructure cracking behaviour. Two different open-graded friction course (OGFC) were prepared using types (calcium...
