Abstract
A pavement restraint structure includes edging pieces having apertures. Connecting elements have protrusions that are secured in the edging aperatures such that adjacent edging pieces have a gap therebetween. Anchoring elements are received by slotted apertures in the edging pieces. Thus, the arrangement enables movement, such as contraction and expansion of the edging pieces along a length thereof. Such movement prevents damage to, or improper shifting of the pavement restraint structure with respect to the pavement due to large changes in temperature of the structure.
Claims23
A pavement restraint structure for providing an attractive edging and preventing outward movement of pavement, said pavement restraint structure comprising:
- a plurality of angled edging pieces each having a support portion and an edging portion, said support portion and said edging portion being substantially perpendicular with respect to each other, said edging portion having upper and lower slots extending substantially horizontally along a length thereof, said edging portion including spaced edging depressions along the length thereof;
- and
- connecting elements slidable into the slots of said edging portions of said edging pieces, said connecting elements each including spaced protrusions for connecting respective adjacent said edging pieces by being received in respective said edging depressions of edging portions of adjacent said edging pieces;
- wherein said connecting elements and said edging pieces, when assembled, comprise said pavement restraint structure;
- wherein said connecting elements connect adjacent said edging pieces such that a gap exists between said adjacent edging pieces and said support portion includes apertures thereon.
A pavement restraint structure for providing an attractive edging and preventing outward movement of pavement, said pavement restraint structure comprising:
- a plurality of edging pieces each having a support portion and an edging portion, said support portion and said edging portion being substantially perpendicular with respect to each other, said edging portion having upper and lower slots extending substantially horizontally along a length thereof and said support portion having support apertures;
- connecting elements slidable into the slots of said edging portions of said edging pieces to form said pavement restraint structure, said connecting elements connecting respective adjacent said edging pieces while maintaining a gap between said adjacent edging pieces;
- and
- an upstanding lip oriented on said support portion and extending along a length of each said edging portions.
A pavement restraint structure for providing an attractive edging and preventing outward movement of pavement, said pavement restraint structure comprising:
- a plurality of angled edging pieces each having a support portion and an edging portion, said support portion and said edging portion being substantially perpendicular with respect to each other, said edging portion having an upper lip extending inwardly and downwardly toward a side having said support portion, said edging portion having a lower lip extending inwardly and upwardly toward said upper lip, said upper and lower lips forming respective upper and lower slots extending parallel to each other along the length of said edging portion of said edging piece;
- and
- connecting elements having a length and a height, said connecting elements each having a curved and downwardly extending top portion at a top edge thereof and extending along the length of said respective connecting elements, said connecting elements each having a curved and upwardly extending bottom portion at a bottom edge thereof and extending along the length of said respective connecting elements;
- wherein said top portion and said bottom portion of each said connecting element are received by respective said upper slots and respective said lower slots of respective said adjacent edging portions of said edging pieces to provide said pavement restraint structure;
- wherein said connecting elements include protrusions spaced along the length thereof, and said edging portions of said edging pieces include edging depressions for receiving said protrusions and securing respective said connecting elements to adjacent said edging pieces while maintaining a gap between said adjacent edging pieces;
- and
- wherein said support portion has along and parallel an edge thereof remote from said edging portion an upwardly extending and inwardly inclined lip.
A method of assembling and installing a pavement restraint structure comprising:
- arranging angled edging pieces adjacent each other, said angled edging pieces each having a support portion and an edging portion, the support portion and the edging portion being at a substantially perpendicular angle with respect to each other;
- securing the pieces to each other by sliding a connecting element into slots at ends of the respective edging pieces;
- forcing the edging pieces toward each other such that a gap remains between the edging pieces;
- securing the support portions of the edging pieces to a support bed for the pavement;
- applying a compactible pavement to cover the support portion of the respective edging pieces of the restraint structure;
- driving a pavement compacting device along the length of the pavement restraint structure no less than about six inches from the edging portion;
- and
- then driving the pavement compacting device over an upper lip of the edging portion of the edging piece.
A pavement restraint structure for providing an attractive edging and preventing outward movement of pavement, said pavement restraint structure comprising:
- a plurality of edging pieces each having a support portion and an edging portion, said support portion and said edging portion being substantially perpendicular with respect to each other;
- at least one connecting element for facilitating an interconnecting of mutually adjacent ends of said edging pieces to form said pavement restraint structure, said at least one connecting element having a spacer mechanism for providing a gap between said adjacent edging pieces during assembly;
- and
- an upstanding lip oriented on said support portion and extending along a length of each said edging portion.
