This paper presents a comprehensive set of experiments on the mechanical and compaction properties of asphalt binders and mixtures modified by the graphene nanoplatelets (GNPs). The experiments involve three commercially available GNP materials with a relative low cost, which are suitable for large-scale industrial applications. This study shows that the addition of GNPs could effectively improve the mechanical properties of the asphalt binders and mixtures, such as flexural strength and fractur...

The use of recycled materials in asphalt pavement is common practice as it yields economic benefits and reduced exploitation of natural resources. Over recent decades, many agencies in the USA have investigated the effect of adding reclaimed asphalt pavement on the field performance of asphalt mixtures used for pavement applications. In this work, the effect of reclaimed asphalt pavement on the low-temperature properties of hot mix asphalt was investigated using two tests: bending beam rheometer...

In this paper, an investigation was performed to determine if the complex modulus obtained from frequency sweeps performed with the dynamic shear rheometer (DSR) can be used to accurately predict the creep compliance obtained experimentally using the bending beam rheometer (BBR). Two sets of asphalt binders were tested at low, intermediate, and high temperatures and the results were analysed using 2S2P1D and DBN rheological models. DSR and BBR testing was performed in two different laboratories ...

Asphalt binder strength significantly affects the durability of asphalt pavements at low temperature. Currently, binder strength is obtained from uniaxial tension tests performed with the Direct Tension Tester (DTT). An alternative bending strength test performed with a modified Bending Beam Rheometer (TE-BBR Pro) that can break small binder beams under load control is presented in this paper. Two factors that can significantly affect results are investigated: the cooling medium in which binder ...

A key material parameter is the Poisson’s ratio. Poisson's ratio is related to the bulk modulus, shear modulus, and Young's modulus, and it is used to determine how the material behaves under various mechanical loading configurations. The current Performance Grade (PG) specification for asphalt binders is based on tests performed in shear using Dynamic Shear Rheometer (DSR) and in bending using the Bending Beam Rheometer (BBR). Interconversion methods relating DSR shear complex modulus and BBR b...

Recycling aged asphalt pavements into new asphalt pavements is a common practice in the pavement industry. The process involves adding the reclaimed asphalt pavement (RAP) into a superheated asphalt mixing drum, where the binder contained within the RAP is expected to melt and be incorporated into the new hot-mix asphalt. Since the RAP is added part way through the mixing process, the amount of time spent inside the mixing drum is short and possibly insufficient for the RAP binder to melt and mi...

A new strength test method for asphalt mixture at low temperatures is presented in this paper. The method uses a modified bending beam Rheometer (BBR), capable of applying loads at different rates. Two major factors, that can significantly affect strength, were analysed: cooling medium and specimen size. Similar strength values were obtained in air and potassium acetate and significantly lower values were obtained in ethanol. Preliminary investigation with sodium fluorescein (FL) indicates the f...
