Abstract
A method of making a roadbed, including paving an area with foamed glass bodies to define a bed and covering the bed with a layer of cementitious material to define a composite bed. The composite bed is at least 85 percent foamed glass bodies. The composite bed has a cementitious surface.
Claims13
A method of making a roadbed, comprising:
- a) paving an area with foamed glass bodies to define a bed;
- and b) covering the bed with a layer of cementitious material to define a composite bed;
- wherein the foamed glass bodies have interconnected open cell porosity;
- wherein the composite bed is at least 85 percent foamed glass bodies in a cementitious matrix;
- and wherein the composite bed has a cementitious surface.
2 more elements
A composite roadbed, comprising:
- a foamed glass aggregate portion filling a roadbed;
- a cementitious matrix portion infiltrating the foamed glass aggregate portion to define a composite bed;
- wherein the composite bed is at least 85 percent foamed glass bodies;
- wherein the foamed glass aggregate portion has an open cell structure;
- wherein the composite material has a specific gravity of less than 0.75;
- and wherein the composite bed has a cementitious surface.
3 more elements
A composite roadbed, comprising in combination:
- a plurality of foamed glass aggregate bodies filling a roadbed;
- a cement matrix infiltrating at least a portion of the foamed glass aggregate bodies and defining a composite bed;
- wherein the composite bed is at least 85 percent foamed glass aggregate bodies;
- wherein respective foamed glass aggregate bodies have an interconnected open cell microstructure;
- wherein the composite bed has a specific gravity of less than 0.75;
- and wherein the respective aggregate bodies remain within the composite bed such that the composite bed has a cementitious surface.
