Asphalt emulsion can be used in a conventional hot mix plant but require lower mix temperatures. The advantage is greatly reduced emissions and less hardening of the asphalt binder. The higher viscosity of the base binder at the mix temperature allows thicker films to be deposited on open-graded aggregates.

Aug 01, 2019 However, to minimize the energy required during asphalt production cold mix asphalt (CMA) may be manufactured at ambient temperatures using bitumen emulsion instead of hot bitumen. Le Bouteiller (2010) reported that emulsion based cold mixed asphalt consumed only 13% of the energy required to produce equivalent hot mixed asphalt at 160 °C. 1.1.

Recycled Asphalt Mixes. Mixes can be made with 100% recycled asphalt pavement (RAP). These mixes are economically and environmentally friendly. RAP mixes can be crushed, graded, mixed and laid on-site using custom-engineered rejuvenating emulsions. Stockpile / Maintenance Mixes. All forms of cold mix can be stockpiled.

asphalt-rubber binders may be used, such as AR Type II or Type III. The choice of binder is dependent on material, traffic, and environmental factors. The first consideration is to use hot applied AC binders or asphalt emulsion binders. AC binders are 100% asphalt, while emulsions are approximately 2/3 asphalt and 1/3 water.

evaporates is called the residual asphalt. Both the amount and type of water and emulsifying agent mixed with the binder affect the evaporation rate. The residual asphalt is expressed as a percentage of the emulsion. The process in which the binder globules begin to coalesce and the water evaporates is called breaking. Asphalt Emulsions
