Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 46 words
A paving material comprising at least about 75% clay as an inert ground substance, the remainder consisting essentially of an acrylic latex emulsion wherein the clay has been baked at a temperature ranging from 600° C. to 1400° C. and ground to a desire grain size.
Claim 2
Dependent Claim 46 words
A paving material comprising at least about 75% clay as an inert ground substance, the remainder consisting essentially of an acrylic latex emulsion wherein the clay has been baked at a temperature ranging from 600° C. to 1400° C. and ground to a desire grain size.
Claim 3
Dependent Claim 21 words
The material of claim 1 wherein said acrylic latex emulsion includes less than about 10% or less of an anti-foaming agent.
Claim 4
Dependent Claim 20 words
The material of claim 1 wherein said acrylic latex emulsion includes about 1% or less cellulose as a sediment-preventing agent.
Claim 5
Dependent Claim 19 words
The material of claim 1 wherein the acrylic latex emulsion includes about 10% or less of a plasticizing agent.
Claim 6
Dependent Claim 32 words
The material of claim 1 wherein the acrylic latex emulsion includes about 1% or less of one or more of an anti-foaming agent, cellulose as a sediment-preventing agent and a plasticizing agent.
Claim 7
Dependent Claim 74 words
A process for obtaining a paving composition which comprises at least about 75% clay as an inert ground material, which clay has been baked at a temperature between 600° C. and 1400° C., and grinding the baked clay before mixing the clay with the acrylic latex emulsion the remainder consisting essentially of an acrylic latex emulsion, comprising beating the acrylic latex emulsion stiff to produce a foam, mixing the foam obtained with the clay.
Claim 8
Dependent Claim 74 words
A process for obtaining a paving composition which comprises at least about 75% clay as an inert ground material, which clay has been baked at a temperature between 600° C. and 1400° C., and grinding the baked clay before mixing the clay with the acrylic latex emulsion the remainder consisting essentially of an acrylic latex emulsion, comprising beating the acrylic latex emulsion stiff to produce a foam, mixing the foam obtained with the clay.
Claim 9
Dependent Claim 36 words
The process of claim 6 including adding about 1% or less of one or more of an anti-foaming agent, a plasticizing agent and cellulose to said acrylic latex emulsion before mixing the emulsion with the clay.
