An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste material...

Rutting of asphalt pavement occurs earlier and is more serious under the increasingly heavy traffic load conditions that can be found in subtropical monsoon climate regions. High modulus concrete (HMAC) with excellent anti-rutting anti-fatigue properties generally used to mitigate this issue. Given relatively high cost additives type asphalt, study feasibility using recycled mixture (RAP) Trini...

This paper presents a computational modeling study of the microstructural influence on damage behavior of asphalt materials. Computer generated asphalt samples were created for numerical simulation in indirect tension and compression testing geometries. Our previously developed micromechanical finite element model was used in the simulations. This model uses a special purpose finite element tha...

The ability to classify asphalt surfaces is an important goal for the selection of suitable non-variant targets as pseudo-invariant targets during the calibration/validation of remotely-sensed images. In addition, the possibility to recognize different types of asphalt surfaces on the images can help optimize road network management. This paper presents a multi-resolution study to improve aspha...

The use of recycled materials in pavement construction has seen, over the years, a significant increase closely associated with substantial economic and environmental benefits. During the past decades, many transportation agencies have evaluated the effect of adding Reclaimed Asphalt Pavement (RAP), and, more recently, Recycled Asphalt Shingles (RAS) on the performance of asphalt pavement, whil...

To determine the behavior of hot mix asphalt including different penetration grade bitumen has been a major subject of paving engineering. In this study the effects of different penetration grade binders on the mechanical properties of hot mix asphalt were investigated with four different tests. The specimens prepared with AC-5, AC-10, AC-20 and SBS modified AC-10. The stiffness modulus, creep ...

To improve the water damage resistance performance of a tuff asphalt mixture, mixture with cement and liquid anti-stripping agent was used as research object, limestone mixtures without additives were selected contrast samples. Through an improved boiling test stability before after aging, modification effect different types contents on evaluated to obtain appropriate type content additives. On...
