Abstract: Asphalt-based compositions for use in the restoration of low-sloped roofs. Compositions are a unique combination of PG asphalts, elastomers, plastomers, plasticizers, and waxes having the unique physical property of providing a functional membrane that can be applied over existing roofing membranes and materials.

Abstract: A field marker arranged for mounting on an agricultural implement at one side thereof includes a marker arm including a marker disk movable between a deployed position extending outwardly of the implement to one side thereof and a retracted position. The marker arm has an inner arm portion and an outer arm portion both of which are formed from two parallel beams with the disk on the outer end of a rear one of the beams. The inner arm portion is pivotal about a first horizontal axis and is supported on a ground wheel spaced outwardly to allow the marker arm to move upwardly and downwardly relative to the implement. The outer arm portion is mounted on the outer end of the inner arm portion for pivotal movement about a second parallel horizontal axis to allow the marker disk to move upwardly and downwardly relative to outer end of the inner portion which is supported on the wheel and to allow the outer portion to move to a retracted position on top of the inner portion.
