Abstract
Synthetic aggregate includes a plastic material and, in some embodiments, an amount of air added into the plastic material. In some embodiments, the plastic material is recycled plastic material. The synthetic aggregate is formed via extrusion of the plastic material and subsequent shaping of the extruded plastic. In some embodiments, the amount of air is added into the plastic material prior to extrusion.
Claims20
A method of forming plastic aggregate, the method comprising:
- feeding at least one plastic material into a hopper of an extrusion machine;
- extruding the at least one plastic material to a desired density in the extrusion machine, thereby forming extruded plastic;
- and
- shaping the extruded plastic into a desired aggregate shape and size, thereby forming plastic aggregate.

8 more elements
A plastic aggregate comprising:
- at least one plastic material, the at least one plastic material chosen based on desired hardness of the plastic aggregate;
- and
- an amount of air added into the at least one plastic material, a ratio of plastic material to air chosen based on the desired hardness of the plastic aggregate.
