ASPHALTS AND BITUMEN

Usually, the terms bitumen and asphalt are used to refer to the same item. These two, however, are very dissimilar. Sand, aggregates, and bitumen are the ingredients of asphalt. Because bitumen is used in asphalt as a binder to keep the material together, asphalt is a concrete mixture, whereas bitumen serves as a binder or pavement cement. The following are some of the points regarding the characteristics of  Asphalts and Bitumen:

Video 01: Difference between Bitumen and Asphalts

  • Asphalt reduces the friction between the vehicle and tires ensuring better consumption of fuel and reduced emission of carbon dioxide. On the flip side, bitumen causes higher friction resistance meaning there is less efficiency in fuel consumption.
  • Asphalt pavements are comparatively more durable than Bitumen pavements.
  • A material that is impermeable is asphalt. Asphalt-based pavements do not leach, lowering the risk of infiltration and groundwater contamination. Leaching is permitted with bitumen that could cause groundwater pollution and soil degradation.
  • Asphalts are more temperature sensitive.
  • You might choose to start with bitumen if you’re looking for a substance that is affordable. Although installing asphalt pavements is more expensive, it only needs routine inspections rather than ongoing maintenance. On the other side, bitumen is less expensive to install, but it will need ongoing maintenance, which could raise the cost over time.
