A screed assembly has two screed sections hingedly connected together at meeting beveled ends. The hing between the screed sections maintains a hinge axis at the soles thereof as one of the screed sections is swung upwardly to define a sloped face for a berm alongside a paving mat as a paving machine with the screed assembly progresses to form the berm and paving mat simultaneously.

A screed extension unit comprising: a slide rail unit adapted to be mounted on a paving machine with a primary screed and having an inner end and an outer end; a slide body unit slidably mounted on the slide rail unit for selectively extending outwardly beyond the outer end of the slide rail unit and beyond one end of said primary screed; an extension screed having an inner screed section mounted at the bottom of said slide body unit and having an outer screed section pivotally mounted at the outer end of the inner screed section for vertical swinging movement in an arc between a lower position aligned with said inner screed section and a raised position sloping upwardly away from said inner screed section, said screed sections each having a respective bottom screed face therealong, with the inner end of the bottom screed face of the outer screed section being substantially in contact with the outer end of the bottom screed face of the inner screed section in all positions of said outer screed section in said arc; and slope adjusting means extending between said outer screed section and said slide body unit for selectively swinging said outer screed section in said arc.
