Material anti-segregation device for a paving vehicle

摘要

A material anti-segregation device is for a paving vehicle including a tractor, a screed for forming a mat of paving material on a base surface, and an auger. The anti-segregation device includes a plurality of flexible, elongated barrier members each coupled with the tractor and collectively defining a curtain. The curtain is configured to generally retain paving material between the curtain and the screed. A plurality of couplers are each configured to connect at least a portion of a separate one of the barrier members with the tractor. Each coupler alternatively disconnects the barrier member or portion from the tractor when tension in the connected member exceeds a predetermined value so as to prevent damage to the tractor. As each barrier member is connected with either a portion or component of the tractor, the predetermined tension value is less than a failure limit of the tractor portion or component.
