Abstract
An illustrative example embodiment of an assembly for making a concrete expansion joint insert includes an extruder a device that receives material from the extruder. The device includes a flow path through the device and at least one internal feature that directs the material away from a middle of the flow path and toward outside edges of the flow path to establish an approximately equal flow rate of the material through the middle and outside edges of the flow path.

A concrete expansion joint insert, comprising
- a recycled rubber body having two ends, two longitudinal edges between the ends, and two side surfaces between the longitudinal edges, the body having a length, a width, and a thickness,
- wherein
- the length is greater than the width,
- the width is greater than the thickness,
- the width and the thickness correspond to dimensions of the ends,
- the length and the thickness correspond to dimensions of the longitudinal edges,
- the length and the width correspond to dimensions of the side surfaces,
- at least a portion of the body has a first surface characteristic,
- at least one of the longitudinal edges has a second surface characteristic that is different than the first surface characteristic, and
- the second surface characteristic comprises a color.
