Abstract
Reinforced concrete is prepared by embedding within it a reinforcing element of at least one rigid plastic gridwork (which is optionally filler reinforced) of integrally molded struts.
Claims34
A process for producing reinforced asphaltic concrete comprising
- (a) pouring a first layer of an asphaltic concrete,
- (b) placing plastic gridwork made of integrally molded synthetic polymer struts in a geometric pattern onto the fresh unhardened top surface of said first layer of asphaltic concrete, and
- (c) covering said plastic gridwork with a second layer of asphaltic concrete.
A process for producing reinforced concrete comprising
- (a) pouring a first layer of an asphaltic concrete,
- (b) placing plastic gridwork made of integrally molded synthetic polymer struts in a geometric pattern onto the fresh unhardened top surface of said first layer of asphaltic concrete, and
- (c) covering said plastic gridwork with a second layer of asphaltic concrete,
- wherein said geometric pattern is formed by regularly repeating units and wherein the cross sections of at least a portion of said integrally molded synthetic polymer struts of said platic gridwork are T-shaped.
A reinforced asphaltic concrete wherein a plastic gridwork made of integrally molded synthetic polymer support struts in a geometric pattern is embedded at the interface between a top layer and a bottom layer of said asphaltic concrete.
A rectangular plastic reinforcing gridwork made of integrally molded synthetic polymer struts in a geometric pattern, wherein each of two adjacent sides of said gridwork has an upturned groove and each of the remaining two sides has a downturned groove.
A rectangular plastic reinforcing gridwork made of integrally molded synthetic polymer struts in a geometric pattern, wherein each of two adjacent sides of said gridwork has an upturned groove and each of the remaining two sides has a downturned groove,
- wherein said geometric pattern is formed by regularly repeating units and wherein the cross sections of at least a portion of said integrally molded synthetic polymer struts are T-shaped.
