Filed:

Jun 14, 2001

Appl. No.:

09/881491

Inventors:

Todd Thomas - Bel Aire KS
Arlis Kadrmas - Wichita KS

Assignee:

KMC Enterprises, Inc. - Wichita KS

International Classification:

E01C 900

US Classification:

404 72, 404 75

Abstract:

A method of reconstructing includes taking representative cores of the road, analyzing the cores, selecting a substantially solvent-free emulsion based on climate history, mixing the emulsion and reclaimed asphalt pavement particles to form an asphalt emulsion mix, testing the asphalt emulsion mix for performance using a raveling test, a thermal cracking prediction test by an indirect tensile testing, a moisture susceptibility test utilizing vacuum saturation, and a dry Marshall stability test. It also includes designing a CIR layer based on this test data. It further includes grinding off a layer of the existing asphalt road leaving at least about an inch, adding an emulsion to the reclaimed asphalt pavement particles, applying the designed cold in-place recycling layer to the road, and compacting it.

Assignee:

KMC Enterprises, Inc. - Wichita KS

International Classification:

E01C 732

US Classification:

404 76, 404 75

Abstract:

A method of paving a gravel and/or dirt roadway is provided. This method includes evaluating the roadway to determine if it is an appropriate candidate for emulsion stabilization, rotating a milling head down a roadway to break up gravel and dirt, injecting an asphalt emulsion into the broken up gravel and dirt, and mixing the emulsion with the gravel and dirt so as to form an emulsion stabilized layer. The emulsion stabilized layer is then spread and compacted to create a paved roadway. Following this, a wearing surface may be applied to the emulsion stabilized layer.

International Classification:

G01M 19/00

US Classification:

404 75, 73146

Abstract:

A method of reconstructing a bituminous-surfaced pavement is provided. This method includes evaluating the pavement to determine if it is an appropriate candidate for full-depth reclamation; mixing an emulsion with reclaimed asphalt pavement particles from the pavement to form an asphalt emulsion mix; and testing the asphalt emulsion mix for performance using a cohesion test, a moisture susceptibility test, and a modulus test. In many instances, dirt and/or aggregate from the base layer of the pavement are also included in the asphalt emulsion mix. The invention also includes designing a full-depth reclamation (FDR) layer based on this test data. Once the layer is designed, the bituminous surface of the pavement is pulverized, an emulsion is mixed with the pulverized reclaimed asphalt pavement particles from the bituminous surface and possibly dirt and/or aggregate from beneath the bituminous surface of the pavement, and this mixture is applied to the pavement.
