|SUBJECT:||Design Policy Memo Bridge Approach Slab Layout|
The following layout criteria shall apply to all approach slabs with skew angles up to 30°.
The roadway end of all approach slabs shall be normal to the centerline of the roadway,
where the minimum slab plan dimension used for layout will be 25-0".
Skewed applications must have squared ends to avoid acute angle cracking in the roadway pavement.
This change was requested by the Regions.
Contact Bruce Thill at 705-7393 for questions regarding staging,
stepping, skews over 30° or other approach slab applications.
