Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A paving composition consisting essentially of aggregate the particles of which are coated with a film of bituminous material selected from the class consisting of tar, asphalt, cut back asphalt, and fast breaking and medium breaking asphaltic emulsions present in an amount of from about 2 percent to about 8 percent based on the weight of the aggregate, Portland cement, and water in an amount sufficient to hydrate said cement, the total amount of said bituminous material and Portland cement in said composition being from about 4 percent to about 25 percent.
Claim 2
Dependent Claim
92 words
A paving composition consisting essentially of aggregate the particles of which are coated with a film of bituminous material selected from the class consisting of tar, asphalt, cut back asphalt, and fast breaking and medium breaking asphaltic emulsions present in an amount of from about 2 percent to about 8 percent based on the weight of the aggregate, Portland cement, and water in an amount sufficient to hydrate said cement, the total amount of said bituminous material and Portland cement in said composition being from about 4 percent to about 25 percent.
Claim 3
Dependent Claim
34 words
A paving composition as set forth in claim 1 in which said film contains a fibrous material present in an amount up to about 3 percent based on the weight of said bituminous material.
Claim 4
Dependent Claim
34 words
A paving composition as set forth in claim 1 in which said film contains a filler material present in an amount up to about 18 percent based on the weight of said bituminous material.
Claim 5
Dependent Claim
52 words
A paving composition as set forth in claim 1 in which said film contains a mixture of fibrous and filler materials present in an amount up to about 3 percent of said fibrous material and up to about 18 percent of said filler material based on the weight of said bituminous material.
Claim 6
Independent Claim
126 words
A method of making a paving composition, consisting essentially of the steps of mixing aggregate with a bituminous material to form a film of said bituminous material over the aggregate particles, said bituminous material being selected from the class consisting of tar, asphalt, cut back asphalt, and fast breaking and medium breaking asphaltic emulsions, and mixing said aggregate after said coating step with Portland cement and water, said water being present in an amount sufficient to hydrate said cement, said bituminous material being present in an amount of from about 2 percent to about 8 percent based on the weight of the aggregate and the total amount of said bituminous material and Portland cement in the composition being from about 4 percent to about 25 percent.
Claim 7
Independent Claim
126 words
A method of making a paving composition, consisting essentially of the steps of mixing aggregate with a bituminous material to form a film of said bituminous material over the aggregate particles, said bituminous material being selected from the class consisting of tar, asphalt, cut back asphalt, and fast breaking and medium breaking asphaltic emulsions, and mixing said aggregate after said coating step with Portland cement and water, said water being present in an amount sufficient to hydrate said cement, said bituminous material being present in an amount of from about 2 percent to about 8 percent based on the weight of the aggregate and the total amount of said bituminous material and Portland cement in the composition being from about 4 percent to about 25 percent.
Claim 8
Dependent Claim
27 words
The method as set forth in claim 5 with the addition that up to about 3 percent of a fibrous material is added with said bituminous material.
Claim 9
Dependent Claim
27 words
The method as set forth in claim 5 with the addition that up to about 18 percent of a filler material is added with said bituminous material.
