ABSTRACT:
The invention relates to a composition and process for grading and immediate stabilization of embankments, for example, in road, levee or canal construction. Use of a mixture of rip rap and loam permits the construction of a steeper embankment than has previously been possible with inexpensive materials and unskilled labor thereby conserving valuable space along the embankment. It also provides for immediate stabilization eliminating erosion during construction. The loam and rip rap may be premixed or, alternatively, the loam may be interjected into preplaced rip rap, for example, in a water slurry. Additional stabilization is provided due to the fact that an embankment made according to this invention will support vegetation and other plant life and ultimately result in an indestructible, interwoven stabilization medium. The planting of vegetation can be varied to suit the climate involved or the particular purpose intended, i.e., wildlife cover and food. Ultimately this process of stabilization will provide a more aesthetic end result.
