Asphalt is a relatively cheap to pave the driveway or asphalt corridor outside his home and properly installed option can last decades. Like many building projects, the longevity of asphalt paving project is in the Foundation. Properly prepared based asphalt can withstand the weight of vehicles and people for a long period of time. Using the right techniques to excavate, lay a foundation and finally add the asphalt ensure a project of flexible pavement.
- Map the area where you want to install your asphalt. Use paint mark or wooden stakes tied with nylon cords to create a pattern that indicates where the asphalt will be installed.
- Push outside its installation depth of 20 inches. Use a tape measure to maintain uniform throughout the area of the entire installation depth. The soil will get firmer and relatively compact, providing a solid base for the asphalt.
- Tamp the surface of the ground with a hand tamper or plate compactor to create a solid foundation. Use a level to make sure the floor is completely flat in all areas.
- Cover the excavated geo-tech fabric area, also called filter fabric or gardening. This tissue prevents weeds growing on the asphalt and helps to drain rainwater.
- Add a layer of 10 inches of gravel to the excavated trench, working in multiple thin layers. Pour a 2-inch layer of gravel, extend out evenly over the entire surface with a shovel or hoe and then compact it or push it to keep all levels. Add four layers of 2 inches, compacting each, until it reaches the gravel 10 inches thick. The gravel helps drainage and helps to withstand the pressure that is placed on the asphalt.
- Measure 6 inches from each edge of the excavated area and mark this place with marking paint. The gravel should extend beyond the edge of the asphalt for better support. Only install asphalt marked lines.
- Pour the asphalt on the surface, filling only the marked lines. Use the same procedure used for gravel and compacting thin layers chickens each, to fill the excavated area. The asphalt must sit ¼ to ½ inch of the surrounding soil to allow drainage. Continue until the area is completely covered. Follow the manufacturer’s instructions regarding how long to avoid traffic on the new asphalt.
