Question 4

Submit Additional Question for Question 4

Due to the asphalt concrete that is underneath the concrete pavement there are concerns that the asphalt could come up in chunks with the concrete pavement removal operation. If the asphalt comes out, what will the NDDOT require the contractor to replace it with? Gravel, milings, asphalt or concrete?

DOT Response

Voids deeper than 1" after removals will be required to be filled with aggregate per Standard Specification 570.04.C.1

Question 3

Submit Additional Question for Question 3

Will any PCC Pavement Grinding be required and paid for in the Passing Lane in the WB Lanes? The table in the plans shows the Driving Lanes only. With pavement repairs being required in the Passing Lanes as well, will the NDDOT be profiling the Passing Lane as well to meet the IRI Special Provision, or will these areas be checked with a straight edge?

DOT Response

Grinding will only be paid for in the driving lane per SP 299(25).  No grinding will be paid for in the passing lane however may be required should a repair area not meet ride quality standards using the straight edge method per 570.04.G

Question 2

Submit Additional Question for Question 2

PCC PAVEMENT GRINDING: After construction of CPR repairs, grinnd surface of the driving lane according to Specification 507.04F. Grind the 12 ft lane with a 1 ft feather pass on both sides of the lane. Transverse Joint Sealing will be incidental to PCC Pavement Grinding. I attached the note on the transverse joint sealant. I understand it to be incidental, but is the DOT expecting all transverse joint sealant to be removed after grinding is completed and then resealed. Or will this be a judgement made in the field?

Additional Questions

For the full depth repair areas, can the pavement area that needs to be resealed to be done with Hot Pour as shown per Section 20 Sheet 1? Or is the NDDOT requiring backer rod and silicone for these areas? For the sealing that may be required after the PCC Pavement Grinding, is the NDDOT requiring backer rod and silicone sealant? You referenced Section 570.04.H.1. That states silicone sealant. Wanting to clarify if hot pour would be acceptable for these joints.

DOT Response

Transverse joints will be required to be cleaned and resealed per NDDOT Standard Specification 570.04.H.1

 

Per section 105.05 of the Standard Specifications, the plans take precedence over the Standard Specifications, therefore hot joint sealant as called out on section 20 sheet 1 of the plan set would be required to seal the joints.
