An Introduction to Asphalt Emulsions | Asphalt magazineAsphalt cement is the basic ingredient of asphalt emulsions. In most cases, it makes up from 50 to 75 percent of the emulsion. Some properties of the asphalt significantly affect the finished emulsion. But there is not an exact correlation between the properties and the ability to emulsify the asphalt.

Minnesota LTAP | Topics: Hot Mix Asphalt Structural DesignThe combined 2360/2350 (Gyratory/Marshall Design) is Mn/DOT's most current specification for construction of HMA pavements. This specification gets updated frequently, so the designer should be sure to obtain the most current specification from Mn/DOT for use in his/her plans and special provisions.
Minnesota LTAP | Topics: Hot Mix Asphalt Mix DesignThe Marshall Mix Design method specifies an asphalt cement binder content at a density that meets the requirements of minimum stability for calculated traffic conditions. The Marshall Mix Design method was developed by the Mississippi Highway Department in 1939 and was originally used for airfield pavements.
State Transportation Innovation Council (STIC)State Transportation Innovation Council (STIC) 2015 Fact Sheet Warm-mix asphalt is a relatively new technology that allows hot-mix asphalt producers to mix pavement materials up to 120 degrees Fahrenheit cooler than traditional mixing at an asphalt plant. The change in temperature may seem insignificant, but the benefits are quite the opposite.
NCAT Report 19-01 PRELIMINARY EVALUATION OF RECYCLED ASPHALT ...A recycled asphalt shingles (RAS) using warm mix asphalt (WMA) field demonstration was conducted in Wilson, North Carolina in June 2015 to compare using post-consumer RAS (PC RAS) and manufacturer waste RAS (MW RAS). Mixes were produced using both types of RAS in conventional hot mix asphalt (HMA) and WMA. The WMA technology used the

How to Successfully Achieve Cold Weather Asphalt PavingWhen placing hot-mix asphalt (HMA), ensure that the mix temperature is a minimum of 290 degrees F at the mid-depth of the mat behind the screed when the compaction process begins.
W MIX ASPHALT (WMA) - mix asphalt (WMA) is a general term describing the use of any additive or technology that allows for lower asphalt plant mixing temperatures. Developed in Europe, WMA was brought to the United States in 2004 and has since gained widespread use around the country. Environmental benefits experienced with
