    摘要: There is provided a hip, ridge, or rake shingle, which includes a shingle panel and at least one rigid back member. The shingle panel has a substantially planar lower surface. The at least one rigid back member has a length substantially the same as or greater than the length of the shingle panel. The rigid back member is attached to the substantially planar lower surface of the shingle panel. the rigid back member includes a step in thickness in a cross-sectional plane perpendicular to the substantially planar lower surface and parallel to the longitudinal axis of the rigid back member. In addition, the thickness of the rigid back member at the high level of the step is greater than the thickness of the rigid back member at one of its ends. There is also provided an asphaltic adhesive including from about 62% to about 99% by weight of an asphalt cement; from about 0.5% to about 15% by weight of a first thermoplastic having a glass-transition temperature in the range from about 190° F. to about 260° F.; and from about 0.5% to about 15% by weight of a second thermoplastic having a glass-transition temperature in the range from about −55° F. to about 0° F.
