Understanding Asphalt Concrete for Road Construction

Is it true that asphalt concrete is used to repair both asphalt and Portland cement concrete pavements?

The correct answer is option A.

Introduction to Asphalt Concrete

Asphalt concrete is a composite material that consists of asphalt binder and mineral aggregates. This mixture is then combined with other materials to create a versatile material used for paving roads, runways, and parking lots.

Portland Cement Concrete

On the other hand, Portland cement concrete is a composite material made of cement, water, sand, and coarse aggregates. It is commonly used for constructing pavements, sidewalks, and other structures.

Application of Asphalt Concrete

Asphalt concrete is often utilized to repair both asphalt and Portland cement concrete pavements. It can be applied as a thin overlay to rejuvenate and reinforce the existing surface of the pavement. Additionally, it can be used as a thicker layer to completely replace the pavement structure, providing a durable and smooth surface for transportation.
