In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...

In recent decades, porous asphalt has been extended for surface drainage in various regions throughout the world. The permeability of porous asphalt has an important role in the performance of asphalt pavements in the rainy weather. The most remarkable problem related to the porous asphalt is its short service time. Considerable efforts have been made to enhance the mechanical properties of por...

Crumb rubber powder is a successfully used renewable material obtained from waste tire rubber, which has been incorporated into paving asphalt since the 1930s due to its good resistance deformation and fatigue as well eco-friendly performance. In this study, carbon nanotubes nano silica were terminal blend crumb modified technology remedy issues of excessive desulfurization degradation ground t...

To the Editor, Pica refers to an abnormal appetite for non-edible substances usually occurring in children with developmental disability or brain injury. However, it can also occur during adulthood, as it is associated with iron deficiency. Pica requires medical attention in case of severe eating behaviour that can be potentially harmful. Here we present a case of craving for Johnson's ® baby t...

the polymeric and non-polymeric petrochemical wastes are environmentally unfavorable materials. we have to found a way to reuse these wastes in a safe manner. in styrene-butadiene rubber (sbr) production plant two major wastes are produced one is a fine rubber powder and the other is recycled n-methyl pyrrolidone (nmp). in high-density polyethylene (hdpe) production plant also a low molecular w...

Superhydrophobic materials have a good application prospect in self-cleaning, anti-fouling, anti-corrosion, and anti-freezing. However, creating large areas of simple, efficient, environmentally friendly superhydrophobic surfaces remains huge challenge. In this paper, surface preparation method is used based on 107 silicone rubber adhesive. A coating with micro/nano structure was constructed th...

Stability is a measure of the strength an asphalt mixture in resisting deformation due to loading. If road construction structure cannot withstand existing load, it will result damage that endangers users. This study aims improve stability concrete with use crumb rubber. Crumb rubber used because has good resistance and elasticity. The research was conducted experimentally by making test object...

In this paper, three composite agents (i.e. emulsified asphalt, EA; styrene butadiene rubber, SBR; rubber powder, RP) were employed to modify the cement stabilized macadam (CSM) for optimal design of semi-rigid base materials. The feasibility utilizing EA/SBR/RP composites in is investigated from perspectives modification mechanism and durability performance. To investigate effects different mo...
