Abstract
Abstract A mat construction usable in the construction, mining and the like industries wherein tire beads from used tires are tied together into an array with the use of strips of used tire casing. The mat can be used as an underlayment for roadways built over unstable ground surfaces, or a number of the mats can be superimposed one upon the other to form a blasting mat. The mats can be formed by inexpensive laborers at the construction site, for example.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A method for laying a road surface over unstable ground surfaces comprising the steps of placing the mat of a two-dimensional array of circular tire beads arranged in linear rows and columns extending at right angles to each other, and fastening means securing said tire beads together into a mat only at their peripherally facing surfaces over the unstable ground surface such that said beads are in proxial relation for ensuring the beads are placed in tension as well as compression under roadway loads, and thereafter pouring at least one layer of road base course material over the mat, whereby the weight of a vehicle traveling over the road surface will be distributed over the entire area of the mat.
Claim 2
Independent Claim
120 words
A method for laying a road surface over unstable ground surfaces comprising the steps of placing the mat of a two-dimensional array of circular tire beads arranged in linear rows and columns extending at right angles to each other, and fastening means securing said tire beads together into a mat only at their peripherally facing surfaces over the unstable ground surface such that said beads are in proxial relation for ensuring the beads are placed in tension as well as compression under roadway loads, and thereafter pouring at least one layer of road base course material over the mat, whereby the weight of a vehicle traveling over the road surface will be distributed over the entire area of the mat.
Claim 3
Independent Claim
106 words
A method for forming a blasting mat from the mat construction of a two dimensional array of circuit tire beads arranged in linear rows and columns extending at right angles to each other, and fastening means securing said tire beads together into a mat only at their peripherally facing surfaces such that a force of a blast is transferred from bead to bead by said fastening means, comprising forming a number of said two-dimensional arrays of tire beads and superimposing one array upon another over a blasting area such that the centers of the tire beads of the respective layers are not aligned with each other.
Claim 4
Independent Claim
106 words
A method for forming a blasting mat from the mat construction of a two dimensional array of circuit tire beads arranged in linear rows and columns extending at right angles to each other, and fastening means securing said tire beads together into a mat only at their peripherally facing surfaces such that a force of a blast is transferred from bead to bead by said fastening means, comprising forming a number of said two-dimensional arrays of tire beads and superimposing one array upon another over a blasting area such that the centers of the tire beads of the respective layers are not aligned with each other.
Claim 5
Dependent Claim
17 words
The method according to claim 2 wherein said fastening means includes strips for tieing together said beads.
Claim 6
Dependent Claim
14 words
The method according to claim 2 wherein said fastening means including tire casing strips.
