  1. Warm Mix Asphalt: The Best of Both Worlds Hot Mix Asphalt is known for its durability. Since the aggregate materials of bitumen, gravel, sand, and asphalt mixture are forged in heat, the binding force is strong enough to withstand changes in the weather. It can even melt ice quicker than cement-based roads. Asphalt is a better alternative to concrete for areas with extreme weather conditions specifically because it is more resistant. However, hot mix asphalt can be quite expensive (compared to cold mix asphalt) and it also needs to be applied in environments with temperatures of over 40 degrees Celsius. Cold Mix Asphalt Budget constraints and temperature requirements result in the use of cold mix asphalt. This type of asphalt is produced when you do not use hot mix bitumen, and pour the asphalt mixture directly on the area that needs to be repaired. Cold mix asphalt is used to repair cracks and holes in hot mix asphalt during the colder season of the year.

  2. However, cold mix asphalt is not as durable as its “hotter” counterpart. It can break with continued exposure to the elements. While it is cheap, it is likely that you may need repeated applications in the long run. The Warm Mix Asphalt Considering the wide difference between the two, the best type of asphalt would be somewhere in between. Warm mix asphalt has the same traits of hot mix asphalt: resistant to weather conditions and durable. However, it does not require extreme temperatures like hot mix bitumen compounds. The secret is the new Lintec Ecological Processing 95 (LEP95) patented warm asphalt mix system. LEP 95 has a working temperature range of 95 to 100 degrees Celsius, which is significantly lower than conventional systems, thereby saving on energy consumption and bitumen mix plant emissions. Benefits of Warm Mix Asphalt Lintec launched its LEP 95 warm asphalt mix system as an add-on component for new plants or integrated with existing asphalt plants. The bitumen plant can produce both hot and warm mix asphalt, depending on the requirements of the project. The system output is a smooth and stable foam which is specifically formulated for optimum mixing results even at low temperatures. Since it does not need high temperatures, there are recorded energy savings of as much as 40%, with 35% savings from pollution control because of the reduced CO2 and bitumen mix plant emissions. Thus, with continued use of LEP95, the carbon footprint of asphalt mixing plants will be greatly reduced. With less impact on the surrounding environment, there would be less stringent pre-installation requirements imposed by local governments. For the bigger picture, asphalt production will no longer be seen as an environmental hazard. The bitumen hot mix plant could be replaced by warm mix asphalt. These vast improvements do not require purchases of new equipment. The same rollers and pavers used for hot mix asphalt can also be used. It is also compliant with European
