Embodiment Construction

[0030] First refer to Figure 1 to Figure 3 , the present invention is used to obtain the terrain profile of the roadbed, and then transport asphalt mat systems and devices with different thicknesses, that is, the paving machine 1, according to the profile. The system can provide varying mat thickness across the width of the mat as well as along the length.

[0031] The first step of the paving process according to the invention is to obtain the topographical profile of the surface to be paved. This step is performed by means of a scanning device 10 which is moved over the road surface to obtain a profile of the entire length and width of the surface to be paved. The scanning device 10 can utilize any known means for obtaining a detailed terrain profile, and radar, sonar, or laser surveying devices used in conjunction with a global positioning system (GPS) are most commonly used. The profile data generated by the scanning device 10 is stored in an easily accessible data stor...

Abstract

A system and device, paving machine (1), is disclosed for obtaining a topographical profile of a road bed, and then delivering an asphalt mat that varies in thickness according to that profile. The system enables variance in the mat thickness across the width of the mat as well as in the normal longitudinal direction. The process is begun by obtaining a three-dimensional profile of the surface tobe paved. A scanning means (10) is moved over the road surface to obtain a profile of the entire length and width of the surface to be paved to obtain a detailed topographical profile. In a second phase of the operation, the scanning means (10) is utilized in combination with an asphalt delivery mechanism, and a mat of asphalt of varying thickness is delivered.

Description

technical field [0001] The present invention relates generally to road construction equipment, and more particularly to multi-dimensional asphalt delivery and compaction systems that deliver asphalt onto road surfaces based on topographical scans of roadbeds. Background technique [0002] Various different types of equipment are used to provide hard surfaces to streets, highways, parking lots, etc. One of these plentiful pieces of equipment available is an asphalt paving machine, which uses screeds to level a layer or mat of asphalt material on the subgrade. Ideally, asphalt paving creates a relatively flat surface for smooth passage of passing vehicles. Thus, rather than gradual curvature and intentional "bumps" (to facilitate drainage of surface water) to create subsurface zones, asphalt pavers lay down the mat to provide a substantially flat surface. This result is optimal if the underlying subgrade has a relatively flat surface. [0003] After the mat is placed by th...
