207 - Obliterating Roadway
GENERAL DESCRIPTION
Definitions of Terms
Concrete Pavement: Concrete pavement is a hard surface made of concrete, used in the construction of roads, runways, and other paved surfaces. Grading: Grading is the process of adjusting the level of land, either by cutting or filling, to achieve the desired contour for construction purposes. Hot Mix Asphalt (HMA): Hot mix asphalt is heated and placed at temperatures between 300 and 350 degrees Fahrenheit. It is primarily used for roads and pathways. Mulch: Mulch is a layer of material applied to the surface of the soil, typically used to retain moisture, reduce erosion, and provide nutrients as it decomposes. Scarify: Scarifying is the process of breaking up hard or compacted materials, typically the existing road surface, using an excavator with a bucket with teeth. Topsoil: Topsoil is the uppermost layer of soil, usually the top 2 to 8 inches. It has the highest concentration of organic matter and microorganisms.
General Overview
Obliterating roadway is the process of removing or rendering unusable road sections (concrete or asphalt) that lie outside the new construction limits. This may include filling ditches, grading operations to blend the area with surrounding contours, or construction of naturally appearing obstructions to deter traffic use. Additionally, scarifying the obliterated roadway may be necessary along with topsoiling, seeding, fertilizing, and mulching the area to promote the natural growth of vegetation. This process ensures the landscape is rehabilitated and prevents environmental degradation that could result from abandoned roadways.
