As an emulsion, bitumen emulsion is considered as an oil in water (O/W) emulsion system with water (or soap) as the continuous phase and bitumen as the dispersed phase. As a result, the cold mix emits less ozone-depleting hydrocarbons. Furthermore, there are fewer hazards of fire and burns, and the process consumes less energy. Bitumen emulsions have a significant advantage over hot bitumen since their operations need less energy because their viscosity is lower than that of hot bitumen. Bitumen emulsions are an innovative method for liquifying bitumen by dispersing it in water. its applications are quite diverse, including cold recycling mixtures, tack coating, and surface treatment. This review paper aims to enable the ultimate potential of bitumen emulsion by further reviewing the research progress of bitumen emulsion manufacturing and discussing the literature available up to now on this topic, in the realm of bitumen emulsion manufacturing and emulsion chemistry.īitumen emulsion is becoming more popular in the pavement construction sector. Therefore, discussing some important issues in this field could be useful to offer a practical guide for bitumen emulsion manufacturers when trying to formulate a well-defined bitumen emulsion to best fit its use in pavement infrastructure rather than to simply to meet standard specifications. Some of them have technical limitations to be utilized for practical industrial application, whereas others are still not understood enough to be applied in bitumen emulsion formulation. Several pre-established formulation procedures have been presented in the literature. Consequently, obtaining the desired product is mostly based on a series of random and tedious trials because of the enormous number of tests that are carried out to meet the required properties, such as emulsion stability, viscosity, droplet size (and distribution), and bitumen emulsion chemistry. The bitumen emulsion formulation process and compositional optimization are subjected to a high number of degrees of freedom. However, there are still scientific and technical obstacles standing against its regular application. One group of those materials is produced by using bitumen emulsion.

His son Justin, CEO of Vestal Asphalt, Inc., spoke to Neil’s contributions during the recognition dinner and presented him with the award along with AEMA President, Mark Ishee of Ergon Emulsions. Guiles has served multiple times as board member and past president of both the Liquid Asphalt Distributors Association of New York (LADA of NY) and the Pennsylvania Association of Asphalt Materials Applicators (PAAMA). He is one of only two people to have served as President of both AEMA and the International Slurry Surfacing Association (ISSA) during his tenure. and has been an active member & Director of AEMA for more than 30 years. In 1983, he incorporated as Vestal Asphalt, Inc. Guiles’ involvement in manufacturing and applying liquid asphalt emulsions dates back to the 1970’s when he founded his first company, Neil I. The organization’s Hall of Fame Award is given to a person who has made a substantial contribution over a long period of time to the development of AEMA or the advancement of the emulsion industry. President, Neil Guiles was inducted into the Asphalt Emulsion Manufacturers Association (AEMA) Hall of Fame at the group’s Annual Meeting and awards banquet last week.ĪEMA is a proactive organization dedicated to the advancement of the asphalt emulsion industry, constantly focusing on system preservation and the construction of the world’s infrastructure.
