Abstract
Abstract A rubber paving installation and method utilizes reprocessed rubber from automobile tires, or the like, or any other suitable natural or synthetic rubber which is processed into a condition to be vulcanized, applied to a surface to be paved, and vulcanized in place. The outer surface of the paving may be vulcanized to a higher degree than the remainder of the paving layer. The paving is particularly suitable for roadways and may be applied to any suitable roadbed such as a gravel and tar bed, or a concrete or black top bed, to provide a vulcanized rubber road.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
75 words
A METHOD FOR SOLIDIFYING A CARBON BLACK REINFORCED POLYMER ON A SURFACE TO WHICH SAID POLYMER IS SELF-ADHERING COMPRISING THE STEPS OF: A. FORMING A CARBON BLACK REINFORCED POLYMER COMPRISING A SYNTHETIC POLYMER AND CARBON BLACK, B. PREPARING A SOLIDIFICATION COMPOSITION CONSISTING ESSENTIALLY OF SAID CARBON BLACK REINFORCED POLYMER AND A SOLIDIFICATION AGENT, AND C. APPLYING SAID SOLIDIFICATION COMPOSITION TO THE DESIRED SURFACE, AND D. ALLOWING SAID COMPOSITION TO SOLIDIFY ON SAID SURFACE, SELF-ADHERING THERETO.
Claim 2
Independent Claim
75 words

Claim 3
Dependent Claim
15 words
The method defining claim 1, wherein said solidification process is carried out at ambient conditions.
Claim 4
Dependent Claim
15 words
The method defining claim 1, wherein said solidification process is carried out at elevated temperatures.
Claim 5
Dependent Claim
28 words
The method defined in claim 1, wherein said carbon black reinforced polymer is produced by plasticizing scrap material selected from the group consisting of rubber and synthetic plastics.
Claim 6
Dependent Claim
23 words
The method defined in claim 1, wherein said solidification agent is one selected from the group consisting of vulcanizing agents and gelling agents.
Claim 7
Dependent Claim
25 words
The method defined in claim 1, wherein said synthetic polymer is at least one selected from the group consisting of synthetic plastic and synthetic rubber.
Claim 8
Dependent Claim
22 words
The method defined in claim 1, wherein said surface is an asphalt road and said composition chemically bonds to the asphalt road.
Claim 9
Independent Claim
154 words
The method for solidifying a carbon black reinforced polymer on a surface so that said polymer self-adheres thereto comprising the steps of: A. forming a carbon black reinforced polymer comprising a synthetic polymer and carbon black by plasticizing scrap material selected from the group consisting of used rubber tires and commercial plastics; B. preparing a rubber paving composition consisting essentially of between about 89% and 91% by volume of said carbon black reinforced polymer, about 5% by volume of at least one accelerator, between about 3% and 4% by volume of a vulcanizing agent, and between about 1% and 2% by volume of an activator; C. heating said rubber paving composition to about 300*F.; D. stirring said rubber paving composition at said elevated temperature until said composition starts to vulcanize; E. pouring and spreading said rubber paving composition over the desired surface; F. allowing said composition to vulcanize directly to said surface, self-adhering thereto.
Claim 10
Independent Claim
154 words
The method for solidifying a carbon black reinforced polymer on a surface so that said polymer self-adheres thereto comprising the steps of: A. forming a carbon black reinforced polymer comprising a synthetic polymer and carbon black by plasticizing scrap material selected from the group consisting of used rubber tires and commercial plastics; B. preparing a rubber paving composition consisting essentially of between about 89% and 91% by volume of said carbon black reinforced polymer, about 5% by volume of at least one accelerator, between about 3% and 4% by volume of a vulcanizing agent, and between about 1% and 2% by volume of an activator; C. heating said rubber paving composition to about 300*F.; D. stirring said rubber paving composition at said elevated temperature until said composition starts to vulcanize; E. pouring and spreading said rubber paving composition over the desired surface; F. allowing said composition to vulcanize directly to said surface, self-adhering thereto.
Claim 11
Dependent Claim
54 words
The method of paving a surface with rubber defined in claim 8, wherein said carbon black reinforceD polymer is further defined as comprising approximately 45% by volume of carbon black and further comprising the additional step of: G. adding synthetic polymer or carbon black to bring the quantity of carbon black to approximately 45%.
Claim 12
Independent Claim
83 words
