The Asphalt Process

Hot mix asphalt pavement is a mixture of gravel, crushed rock, and sand mixed with liquid asphalt, a massive by-product of the petroleum refining process. The oil is heated, combined with the aggregate stones and then spread out on the area in a continuous pad until the area is completely covered.

The Base
As with any building process, there has to be a firm foundation beneath an asphalt surface. Paving Companies Northampton will dig down to remove clays, porous soils, old pavement, and concrete. In some cases, the old surface can make a good base, but most times it should be removed. Then a crushed rock base from 6 to 10 inches thick is put down depending on the use of the driveway. A good base will also prevent the surface from cracking or sinking in spots. Also, the crushed rock should be more extensive than the blacktop to account for drainage. It also prevents the edges of the pavement from breaking and cracking if a tire goes too far over to the side.
The crushed rock base should be spread in layers with a more substantial, bottom layer three to four inches thick. The stones in this layer should be more significant for holding power.

The bottom layer will be heavier gravel or crushed rock. It will be rolled and shaped, and then a lighter mix will be applied after a coating of asphalt cement is spread on to bind the layers. This finishing layer will be thin, about 1†to 1 ¼â€ and be composed of coarse sand.
Like concrete, blacktop is premixed at a pavement plant. It is delivered by truck and dumped into a spreader that puts the asphalt down in a vast, continuous strip. Then a mechanized roller compacts the pavement, pressing it into the base of crushed rock.
To give the surface a long life, a driveway sealer should be applied yearly. This seal coating prevents the aggregate from breaking down.
