Bitumen 60/70 Uses in Road Construction
Bitumen 60/70 is a commonly used grade of bitumen in road construction, particularly for paving. Here are Bitumen 60/70 of ASIA BITUMEN some uses in road construction:
Asphalt Mixes: Bitumen 60/70 is used to create asphalt concrete (bituminous concrete), which is a composite material used to surface roads, parking lots, airports, and other areas. The bitumen binds the aggregates (like sand, gravel, and crushed stone) together, forming a durable surface.
Pavement Surfacing: This grade of bitumen is used for creating the top layer of road pavements. It provides a smooth, weather-resistant, and skid-resistant surface that can withstand the load of traffic.
Waterproofing: In road construction, Bitumen 60/70 is also used for waterproofing layers to prevent water ingress, which can damage the pavement structure over time.
Seal Coating: Bitumen 60/70 is used in seal coating to protect and extend the life of the pavement. Seal coating is applied to the road surface to provide a protective layer against the effects of traffic, weather, and other environmental conditions.
Repair Work: This bitumen grade is used in repairing potholes, cracks, and other road surface defects, ensuring that the repairs are durable and long-lasting.

Tack Coating: Bitumen 60/70 is often used as a tack coat, which is a thin layer of bitumen applied between the existing pavement and a new asphalt overlay. This ensures good bonding between the layers.
Base Course Construction: It is used in the base course of road construction, where it stabilizes the foundation and provides a strong base for the upper layers.
The choice of Bitumen 60/70 is often due to its suitable properties, such as its viscosity and durability, which make it ideal for hot climates and roads with moderate to heavy traffic.
