US5512093A - Hot mix asphalt and method of preparation ...

A method is shown for improving the properties of hot mix asphalt by treating the aggregate which is combined with bituminous binder with lime. A hot quicklime slurry is produced by slaking quicklime with water at the site of the hot mix asphalt plant using a portable mixing tank. The hot quicklime slurry is then applied to the aggregate, the aggregate is dried and combined with the binder to ...

Study on preparation and thermal performance

For CPCMs used in hot mix asphalt mixture, the thermal stability also puts forward higher requirements. According to specification , the mixing temperature of asphalt is 160–170 ℃, and the transportation temperature is not lower than 150 ℃. So, the CPCMs must still have good thermal stability at 170–180 ℃, that is, no chemical ...

Process for the preparation of a cold mix asphalt paving ...

Asphalt may be treated for use in paving compositions by using one of two conventional methods. These methods are appropriately called the "hot mix" and "cold mix" methods. In the hot mix process, the asphalt is liquified at approximately 300° F. to 350° F. by heating.
