International ClassE01C 011/22AbstractA 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. | |
