METHOD OF COVERING AN AREA WITH A LAYER OF COMPRESSIBLE MATERIAL
First Claim
1. A method of paving an area with asphalt to a desired elevation using an asphalt paving machine that deposits a mat of asphalt of a controlled thickness on a foundation surface, and then using a compacting machine to compact the asphalt to the desired elevation, comprising the steps of:
- determining the elevation of the foundation surface over the area,determining the difference between the elevation of the foundation surface and the desired elevation over the area,depositing a mat of asphalt over the area, said mat having a thickness that varies over the area, with the mat being thicker in the areas having a lower foundation elevation and thinner in the areas having a higher foundation elevation, said mat being sufficiently thick to allow for compression of said mat over said area to said desired elevation, said mat having a thickness that is substantially a constant K times the difference between the desired elevation and the elevation of said foundation surface at each of a plurality of points spaced over said area,compressing said mat of asphalt during one or more compression operations such that the upper surface of said mat is uniformly at said desired elevation over said area,determining the elevation of the upper surface of said mat after compression, andadjusting the value of K to compensate for determined offset from the desired elevation of the upper surface over said area.

Abstract
A method of covering an area with a compressible material, such as asphalt, to a desired elevation using a machine that deposits a layer of the compressible material of controlled thickness on a foundation surface, and then using a compacting machine to compact the compressible material to the desired elevation, includes the steps of determining the elevation of the foundation surface over the area, and determining the difference between the elevation of the foundation surface and the desired elevation over the area. A layer of the compressible material is deposited over the area. The layer has an upper surface that varies in elevation over the area, with the layer upper surface being higher in the areas having a lower foundation elevation and lower in the areas having a higher foundation elevation. The layer is sufficiently thick to allow for compression of the layer of compressible material over the area to the desired elevation. The layer of compressible material is compressed during one or more compression operations such that the upper surface of the layer after compression is uniformly at the desired elevation over the area.
