Abstract
Abstract A method for stabilizing the upper layers of the earth's surface is claimed that comprises the steps of: mixing an amount of lime with an amount of water, simultaneously or sequentially mixing an amount of fly ash with the lime/water mix to form a slurry, distributing said slurry onto the earth's surface and working said slurry into the upper layers of the earth's surface.
Claims14
A method for stabilizing the upper layers of the earth's surface, comprising the steps of:
- a) forming a slurry of lime, fly ash and water in which the slurry has a solids content in excess of 35% by weight and the amount of fly ash is approximately three times the amount of lime by weight.
- b) applying, through means other than injection under pressure, said slurry to the earth's surface;
- and
- c) mixing said slurry into the upper layers of the earth's surface to form a stable soil layer.
A method for stabilizing the upper layers of the earth's surface, comprising the steps of:
- a. mixing an amount of lime with an amount of water;
- b. concurrently or sequentially mixing an amount of fly ash with the lime and water mixture to form a slurry;
- c. distributing said slurry onto the earth's surface by other means than injection under pressure;
- and
- d. working said slurry into the earth's surface.
A method for stabilizing the upper layers of the earth's surface, comprising the steps of:
- a. mixing an amount of quicklime with an amount of water;
- b. mixing an amount of type F fly ash with the lime and water mixture to form a slurry, said amount of fly ash being approximately three times said amount of lime by weight and said slurry having a solids content of from about 35 percent to about 200 percent by weight of water;
- c. distributing said slurry evenly on the surface of the earth by other means than injection under pressure, and
- d. working said slurry into the surface of the earth to form a stable soil layer.
A method of rehabilitating roads having surfaces of asphalt, and concrete, said method comprising the steps of:
- a. pulverizing the old surface;
- b. mixing an amount of hydrated lime with an amount of water;
- c. mixing an amount of type F fly ash with lime and water to form a slurry, the ratio of the fly ash to the lime being from 10:1 to 1:4 and said slurry having a solids content of from about 35 percent to about 200 percent by weight of water;
- d. distributing, without injection under pressure, said slurry evenly on the pulverized surface, and
- e. working said slurry into the pulverized surface and permitting the layer to form into a stabilized layer.
