| PennDOT Pub 408 Rewrite Update and Recent Clearance Transmittals |
|
Recently there has been numerous Clearance Transmittals issued by PennDOT. Most of these have resulted from the work of the “Section Teams” of the Pub 408 rewrite initiative, which began last fall. The original schedule for this work had as a goal that all proposed changes should be out as Clearance Transmittals by February 2019. This would allow for review, comment, and inclusion of their revisions into the April 2020 version of Pub 408.
Many of the sections have completed their work, but there are other items still pending review and publication as Clearance Transmittals. Section 1000 (Structures) has completed most of the work that will affect our material producers. Proposed changes to Section 1001 (Cement Concrete Structures) and 1040 (Concrete Bridge Deck Repair) have recently been issued.
The Section 700 team continues its work and will be issuing changes that affect all of our producers including:
- A new Accelerated Structural Concrete Mix designation – “ASC”.
- An AAAP Lightweight Specification.
Industry members of the Section 700 team will continue to work with PennDOT personnel on these items and others, as work to get these out as Clearance Transmittals continues.
Our thanks to those members who represent our industry on this major Pub 408 rewrite including:
Tom Abbey, Glenn O. Hawbaker, Inc.
Susan Armstrong, Central Builders Supply Co.
Mark Moyer, New Enterprise Stone & Lime Co., Inc.
Claire Nowasell, Lehigh Cement Company
Janki Shah, Allan Myers Materials, Inc.
All of the relevant Clearance Transmittals from this effort have been sent to members of the PACA Concrete Technical Community for their review and comment.
As the Pub 408 rewrite work continues, there will be many more Clearance Transmittals (Step 1 and Step 2 final) issued during the second half of this year. The clearance transmittal process provides our members with an opportunity to comment on specification changes, which must be addressed and considered by the reviewing group, prior to their inclusion in the PennDOT specifications. It is easy to view and comment on these proposed specification changes - just email Jim Casilio, PACA's Director of Technical Services and he will add you to one of our Technical Communities.
