Introduction Of Asphalt Mixture At Different Temperatures

According to different mixing and paving temperatures, asphalt mixture can be divided into three types: hot mix asphalt mixture, cold mix asphalt mixture, and warm mix asphalt mixture. Let’s check the temperatures of different kinds of asphalt mixture first.

Temperatures Of Three Kinds Of Asphalt Mixture

Hot mix asphalt mixture

It require high temperatures during preparation and construction. Typically, bituminous mixtures are prepared at temperatures ranging from 150°C to 180°C. During the laying process, the construction temperature is generally between 120°C and 160°C.

Cold mix asphalt mixture

The cold mix asphalt mixtures do not require high temperatures and are usually prepared at room temperature or with slight heating. Its preparation temperature range is generally between 15°C and 40°C. The cold mix process uses special binders and additives to mix asphalt with aggregate at lower temperatures.

Warm mix asphalt mixture

The warm mix asphalt mixture is between hot mix and cold mix, and uses a lower construction temperature, but still requires a certain heating process. Its preparation temperature range is usually between 110°C and 130°C, and its construction temperature range is between 90°C and 120°C.

Advantages of Using The Asphalt Mixture

Using hot mix asphalt mixture Advantages

  • Higher compactness: due to construction at high temperature, asphalt can better penetrate the aggregate, resulting in a higher density of the mixture, providing better durability and resistance to water loss.
  • Fast curing: The hot mix prepared at high temperature cures quickly and can be put into use quickly, reducing road closure time.
  • Good Durability: Due to compactness and adequate coating, hot mix mixtures generally have a long service life.

Advantges of Using Cold Mix Asphaalt Mixture

  • Energy saving: Compared with hot mixing, cold mixing does not need to consume a lot of heat energy and saves energy.
  • Environmental protection: less waste gas and waste water are produced during the cold mixing process, and have less impact on the environment.
  • Flexibility: Cold mix is suitable for environments with low temperatures, especially for some special road repair work

Superiority of Using Warm Mix asphalt mixture

  • Energy saving and emission reduction: Compared with traditional hot mixing, warm mixing uses less energy and reduces carbon dioxide emissions.
  • Better Performance: Warm mix generally performs better in terms of mix compactness and performance than cold mix.
  • Reduce pollution: less gas and dust are produced during the warm mixing process, which reduces the adverse impact on the environment.
