As an example, the DSR makes it possible for item developers to create toothpaste with the appropriate uniformity to ensure that it can be pressed from a tube however not diminish the tooth brush. The DSR tests binder positioned between two parallel plates regarding the size of a quarter. One of home plates moves and the machine measures the viscoelastic homes of the asphalt.
