The maker was not established for the paving market (https://qualtricsxm4qwdsn59g.qualtrics.com/jfe/form/SV_0H8SwRAI7gGMMQK).


As an example, the DSR enables item designers to create toothpaste with the best uniformity to ensure that it can be squeezed from a tube however not fall off the tooth brush.
