Abstract
A push roll assembly mounted to a material receiving apparatus, such as a paver or other material receiving machine, includes a resilient link which allows energy transferred during contact of a supply truck with the push rolls to be gradually transferred to the material receiving machine, to thereby smoothen the impact between such truck and the machine.
