SSP103F56: - Consider…

SSP103F56:

- Consider revising the definition of cross slope so there is no confusion that a paved shoulder is not to be included. The term edge of pavement usually means the full pavement width including paved shoulders.

- 313.08.01.08.01 – Why do we care about the cross slope only after 1 month? What if the Contract requires or the Contractor plans to cover the binder within 1 month but is delayed? Would this also mean all binders on 400 series highways would be subject to cross slope requirements during construction while they are built in stages? Is the expectation to measure the final through lane alignment when the temporary lane on the binder may be different?

- 313.08.01.08.04 – Consider specifying that the CA and Contractor measure together after final compaction to avoid extensive retesting. Retesting should only be applied for sublots that are rejectable based on CA and Contractor measurement that require additional measurements to determine the extent of the rejectable cross slope within the sublot. Consider adding timelines for the retesting to be done.

- Warrant – Consider including a more detailed exemption list like SSP103F31 that has a “Do NOT include if the Contract…” section in the warrant below a very similar paragraph to this specification’s warrant. For example, cross slope correction should not be included if the contract is a structural rehabilitation and the entire staging area is less than 1 km.

CDED B313:

- Consider adding more guidance to the designer about when to include the cross slope specification and when not to or include a reference to the SSP warrant and update the warrant accordingly.

- Include list of the minimum information about the existing conditions that must be included in the contract package for cross slope correction.

CAIS 313:

- 313.08.01.08.01 – Cross slope lots/sublots should be discussed and established before or at the pre-pave meeting. Consider requiring the CA to submit a lot/sublot sketch for the pre-pave meeting like is required for smoothness in SSP103F31 8.01.02.01.

- 313.08.01.08.03 – SSP says the CA has to provide the PH-CC form to the Contractor within 3 Business Days of completion of the lot, but the CAIS says 1 Business Day still.

- 313.08.01.08.04 – Add that the CA should check if the re-testing is requested within allowable timelines (no later than 1 Business Day from receiving form).
