The ordinary Black diagram of bitumen has only two dimensions. Thus, it does not differentiate the complex shear modulus and phase angle measured under different temperature frequency conditions. This study proposes to extend three dimensions by adding a axis. It leads combination multiple necessary plots in same three-dimensional (3D) space. In this 3D space, location, shape, eventually colour...

This study investigated the impact of using modified bitumen binders and additives to enhance physical characteristics asphalt mixtures at high, medium, low temperatures. Both basic rheological bituminous were tested by adding Styrene-Butadiene-Styrene, a type thermoplastic elastomer, as chemical additive various fractions (3.5%, 4%, 4.5%), two kinds Bitumen: Kraton styrene block copolymers Eur...

Initial processing of Athabasca oil sands obtained from the water-based extraction process yields stable water-in-bitumen emulsions.When the bitumen is diluted with naphtha to reduce its viscosity and density, partial separation can be obtained with a suitable demulsifier. However, a “rag layer” forms between the clean oil and free water layers. The partially oil-wet kaolinite in clay solids ca...

Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits. The mechanism of WMA is to use some additives or technologies to reduce the viscosity of bitumen and to modify the rheological behavior of bituminous binders, and thus improve the workability of the mixture at lower temperature. In this study a paraffin wax based addit...

In this data article experimental data on the compressive strength, and the durability of styrene and bitumen modified sulfur concrete against acidic water and ignition are presented. The percent of the sulfur cement and the gradation of the aggregates used are according to the ACI 548.2R-93 and ASTM 3515 respectively. For the styrene modified sulfur concrete different percentages of styrene ar...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

Molecular dynamics (MD) simulation plays an effective role in predicting the critical properties and explaining macroscale phenomenon at nanoscale. This review summarized application cases of MD simulations various bitumen systems, considering aging, modification, rejuvenation factors. Meanwhile, potential relationships between nanoscale parameters predicted from measured experimental tests wer...

The mechanical and rheological characteristics of bitumen are crucial for the behavior durability bituminous road layers. A susceptible to high temperatures can lead plastic deformation layers, whereas a low temperature binder cracking penetration test at 25 °C, softening point - ring ball method ductility were carried out on 50/70 five types blends. In order determine temperatures, Bending Bea...

the purpose of this research was to evaluate the application of recycled aggregates of constructiondebris such as concrete, cement block and rubbles from pars-kangan site in asphalt concrete mix design. toevaluate the performance of aggregates different mix designs with recycled aggregate percentages of 0, 10,30, 50 and bitumen percentages of 4, 4.5, 5, 5.5, 6, and 6.5 were provided and two mar...

Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...
