Before we lay a new asphalt driveway, consider the stability of the site foundations. Regardless of the asphalt thickness, if it doesn’t have a reliable base, the driveway will weaken faster. A quality base should be compact and stable, and productively drain water. 

An expert asphalt contractors will advise the best direction to take regarding to the base layer. The options are: 

  • Existing Driveways – Laying the asphalt over the existing asphalt driveway assuming that it’s in good condition and the finished level isn’t excessively high. 
  • Unsealed Driveways – Laying the asphalt on an existing layer of road base, limestone, or gravel that has been added to and regraded. 
  • New Driveways – Laying the asphalt over a new aggregate base. This process requires eliminating any existing driveway prior to laying 100-200mm of compacted total as the foundation, followed by the asphalt surface. 

Contingent upon the primary use of the driveway, the asphalt thickness may vary. For residential and commercial driveways, the thickness of the asphalt will be in a comparable range, however it likewise relies upon the base foundation determined above. 

In the event that the driveway solution needs to endure the weight of heavy vehicles more than 10 tons, the base and asphalt thickness should be expanded. 


Common asphalt driveway in Ogden and up in the Valley (liberty, Eden, Huntsville Utah will range between 3 and 4 inches in thickness. The range relies upon the primary vehicles using the surface and the basecourse material and thickness used under.


While laying an asphalt surface, depleting water is pivotal. The drainage process is more dependent on the basecourse and the direction it slopes than the asphalt thickness. In the event that the subgrade is graded to achieve the optimal slant for water run-off, asphalt can be laid at a consistent thickness. At least 1 in 100 (1%) fall or more is alluring for accomplishing ideal drainage run-off. 

With new asphalt, the smooth surface makes the water drain quickly . As the surface ages and oxidizes, the beading decreases, the surface become ruff and the water does not run off as easily. Its time to seal coat.
