By installing the road with Asphalt there is no need of remove and replace for a longs time. Since it is durable but little bit expensive and it gives us the long lasting result.
There are actually two basic Ingredients in Asphalt.
The first is Aggregates. This is a mix of Crushed Stone, Gravel, and Sand. Aggregates make up about 80% of Hot Mix Asphalt pavement.
