Operating in the Southeastern United States, the Miller Group Inc has been located in Morrow Georgia since 1984.
As the leader in the pavement recycling industry, we average over 200 miles of road maintenance, rehabilitation and reconstruction per year in; Asphalt Cold Planing (Milling), Cold-in-Place Recycling of asphalt, Stabilizing subgrade and base construction with the existing in-place reclaimed materials (Full Depth Reclamation).
Clients include the Departments of Transportation, counties, municipalities and private industry for Georgia, Florida, North Carolina, South Carolina, Alabama, Louisiana and Tennessee.
Soil stabilization is an effective process that provides public and private sectors with a strong, durable base and subgrade capable of withstanding a wide range of loads. It creates an improved homogenous, friable material which can be compacted to increase load bearing strength of the in situ materials.
By installing the proper additive a wide range of soil improvements can be made: rapid soil drying, soil modification, soil stabilization, reduced plasticity index, reduced moisture absorption, increased unconfined compressive strength, increased CBR, and reduced swell potential. Agents typically used across North America are lime, Portland cement, fly ash, or liquid chloride.
A geotechnical analysis of the existing materials and consideration of intended loads, life cycle, and climate will help determine the appropriate stabilization method(s) and agent(s) to be used.
Cold Milling is the controlled removal of an asphalt or concrete surface by either a partial or full depth application. When milling partial depth, the resulting textured pavement can be used immediately as a driving surface.
Milling machines are self-propelled and of sufficient size to provide the traction and stability required to remove the pavement surface. Equipped with automatic grade control systems, surfaces can be milled to specified elevations, profiles and cross slopes.
The Recycled Asphalt Pavement (RAP) generated during the Cold Milling operation is loaded onto haul trucks via the conveyor system and transported off site. The RAP can be further recycled through Central Cold Mix and Hot Mix Plants or used to correct profile deficiencies by placing the material on existing granular or bituminous surfaces.
Cold Milling has become commonplace in construction and is now the preferred method of removing and reclaiming pavements. Cold Milling machines are available in a variety of sizes from half meter machines, to half lane and full lane milling machines to accurately remove pavements to suit individual requirements.
Full Depth Reclamation
Full Depth Reclamation (FDR) is a rehabilitation technique in which the full thickness of the asphalt pavement and a predetermined portion of the underlying materials (base) is uniformly pulverized and blended to provide a stronger, homogeneous material.
The quality of the existing materials will dictate the strength of the resultant pulverized material, which in some cases, may not be sufficient to support traffic loads and volumes. If the existing road materials will not provide adequate strength after FDR, virgin aggregate, recycled aggregate, reclaimed asphalt pavement, or crushed concrete may be added. Common Stabilizing Agents are portland cement, fly ash, lime, emulsion, and foamed asphalt.
The reclamation process removes the existing asphalt pavement cracks and deterioration since the entire asphalt layer is pulverized to produce an improved, homogeneous granular material on which a new pavement structure can be placed immediately upon completion. Pavements composed of distorted subgrades are only candidates for FDR when additional work is undertaken to correct drainage and subgrade deficiencies.
Reclaiming machines are very mobile and maneuverable to process a wide range of road geometries including urban environments. Due to its versatility, energy savings and reduced natural resource requirement, Full Depth Reclamation provides asset owners with a cost effective means of rehabilitating roads.
