An overview of crumb rubber modified asphalt
Roadways are considered one of the most important elements of infrastructure and they play an essential role in our daily lives. In road pavement construction, the use of crumb rubber in the modification of bitumen binder is considered as a smart solution for sustainable development by reusing waste materials. It is believed that crumb rubber modifier (CRM) could be one of the alternative polym...
متن کاملEngineering characterisation of epoxidized natural rubber-modified hot-mix asphalt
Road distress results in high maintenance costs. However, increased understandings of asphalt behaviour and properties coupled with technological developments have allowed paving technologists to examine the benefits of introducing additives and modifiers. As a result, polymers have become extremely popular as modifiers to improve the performance of the asphalt mix. This study investigates the ...
متن کاملAn Alternative Asphalt Binder, Sulfur-Extended Asphalt (SEA)
Background In the early 1970s, due to concern over asphalt cement supply issues and an anticipated over abundance of elemental sulfur, many organizations Société Nationale des Pétroles d’Aquitaine (SNPA), Gulf Oil of Canada, Sulfur Development Institute of Canada (SUDIC), Texas Chemical Company, U.S. Bureau of Mines, and the Texas Transportation Institute) began to evaluate the potential for su...
متن کاملCellulose Microfibril/Nanofibril and Its Nanocompsites
Cellulose micro/nanofibril (CMNF) as a reinforcing material for composites is becoming more and more attractive to researchers in composite science because of its potential lightweight and high strength. CMNF is generally prepared by either physical treatment, e.g., by a high pressure homogenizer and/or high pressure refiner, or chemical treatments, e.g., acid hydrolysis. In this study, attempt...
متن کاملThe Use and Performance of Asphalt Binder Modified with Polyphosphoric Acid (PPA)
Background The modification of asphalt binder to improve performance properties has grown significantly since the implementation of the Strategic Highway Research Program (SHRP) binder specifications. There has been increased use of polymers, crumb rubber modifier and Polyphosphoric Acid (PPA). There has been concern by many highway agencies about the performance characteristics of PPA modifica...
