The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the roadengineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. Cold mix asphalt (CMA) emulsion technology could be one of the better options for the road industry to explore more ...

in this study an empirical model which can be used to predict the rutting parameter (g*/sinδ) for neat and powder rubber modified bitumen describes. the model was developed using 36 unique powder rubber modified bitumen combinations, rubber concentrations were varied at 5% intervals between 5 and 20%. the effects of powder rubber particle size on model accuracy were also studied ultimately a mo...

in this study, different contents of nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen tomodify the physical, mechanical and rheological properties of warm mix asphalt (wma). wma iscontaining 2 wt.% of sasobit (mixture of long-chain hydrocarbons). various quality control tests have beencarried out to characterize the modified bitumen and wma. the rheological investigations show...

Abstract Lignin is one of major by-product from wood and paper industry. As natural biopolymer, it could be a valid alternative as bitumen replacement and/or modifier to enhance the relevant performance asphalt mixtures, promoting concurrently environmental benefits. In this context, study focused on effects two different binders containing 30% lignin (by weight) mechanical properties bio-aspha...

Most of the major plant, factory, process, equipment and tool disruptions are preventable, and yet preventative fault detection and diagnosis section are not the norm in most industries. It is not uncommon to see simple and preventable faults disrupt the operation of an entire integrated manufacturing facility. For examples faults such as malfunctioning sensors or actuators, inoperative alarm s...

in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...
