550.1 Safety EdgeSM
Shaping the edge of pavement to a 30° bevel is an effective strategy for mitigating the negative effects associated with vertical edge drop-off. The finished shape of the Safety EdgeSM shall conform to Std. Plan 401.00.
As with conventional paving, the graded material adjacent to the Safety EdgeSM should be brought flush with the top of the pavement following paving. If this material should settle or be otherwise displaced in the future, however, the Safety EdgeSM would continue to provide a durable height transition to smoothly conduct vehicles back to the paved road.
Safety edge must be included in all concrete projects when the finished surface will be 24 ft. wide or greater. The Safety EdgeSM shall be constructed monolithically with the pavement. This includes shoulder paving unless the paved width of each shoulder exceeds 4 ft. When using the Safety EdgeSM, the quantity of concrete will increase by approximately 2 percent.
Prior to placing concrete pavement, prepare the shoulder material where the Safety EdgeSM will be placed to provide a foundation that will support the placement of the Safety EdgeSM in accordance with the standard practice.
Furnish, place and compact shoulder backing material to the top of the Safety EdgeSM, in accordance with agency specifications.
