Installing a new blacktop driveway in Minnesota is a different process than in many other areas of the country. The cold temperatures can cause the ground to heave, so it is necessary to install the right base and then roll it with a vibratory roller. This ensures the best possible compaction. The compaction process is repeated every 2″-3″ until the right thickness is achieved. The base is usually crushed, processed stone which hardens up well when it is rolled over. The base is graded by special graders to ensure that water will drain correctly when the asphalt is laid.
It is best to remove all damaged asphalt before applying new because it will cause the new asphalt to crack and fail to provide a smooth surface. Asphalt Paving Burnsville MN over an existing driveway will not yield good results, because every crack and all of the joints will be seen through the asphalt.
Once the base is ready, paving trucks are specially equipped to bring in hot asphalt which lays easily and forms a perfect pitch to the driveway. Building a solid base is essential so that the asphalt will not have holes or depressions caused by an inadequate sub-base. There are various types of equipment that can be used to lay down the asphalt, and the right equipment will be selected for each job. Asphalt will show the imperfections if the base is in poor condition, and the pavement will look poorly done.
Once the blacktop is laid, the surface is rolled with a vibratory drum roller which provides the smooth and strong finish. The edges are hand tampered to provide a 45 degree angle that will support vehicle weight without breaking down. The Blacktop driveway in Burnsville, MN company will make sure that the surface is smooth and strong.
Asphalt and blacktop are essentially the same product, but there are differences. Asphalt is created by mixing aggregate with bitumen which is a substance found in crude oil. Aggregate refers to stone and sand. Blacktop is created the same way, but typically begins with liquid asphalt being mixed with more stone. Both of these products are heated and once they are cooled, they will become hard, and they will stay hard for many years.
The Asphalt Driveway Company Burnsville MN works with both asphalt & blacktop driveway products in the area of Burnsville, MN.
