MT Phillips 364(1) (RESOL) Short Oil Road
# General Technical Question Answer Date
1 X
Under the Special contract requirements (403.02) it states: Submit a Montana Department of Transportation JMF approved within the past 12 months…….., Is it possible to submit a (new) JMF that has NOT been approved by MDOT but meets all of the their specifications. Since this is not one of their projects, they will not use resources to approve a JMF. Our closest mix design that MDOT has approved in the last 12 months would come from East of Lewistown MT. (145.0 miles away)
This will be addressed under a forthcoming amendment.

It appears that they are calling for 634.04 Solventborne Traffic Paint (Type A). We haven't been able to procure this material for years. I think it’s been phased out of other federal projects and they have been using 634.05 Waterborne Traffic Paint Type B. Please verify.

Pay item # 20303‐1600 – Removal of Pavement, Asphalt. Would the owner entertain recycling the existing asphalt and base? I’ve read the pavement report, but utilization of all the existing material that’s in place would help decrease the subgrades exposure pumping of clay soil due to wheel traffic.

Per special contract requirement 403.01, the asphalt binder designated for this project is PG 58‐34. Would the owner entertain using a different grade of asphalt binder? The designated binder appears to be limited in regional availability. Most of the past projects that we’ve encountered in this tri‐county area from the MDOT contain PG 64‐28 asphalt binder. If the owner entertained at least an alternative pricing bid item, it might give some perspective for cost comparing.

We’ve received your question and a response is forthcoming.

No. 2/7/2020
8 X Did you receive my questions sent on Friday (1/31/20)? Please let me know if a reply is forthcoming or not.
Yes, a response is forthcoming. 2/7/2020

A big concern that I have is with the MDOT mix that is spec’d. I am not familiar with the MDOT ever using a PG 58‐34 in their mixes. A passing Hamburg rut test is required as part of their mix design acceptance. With this softer oil, will a passing Hamburg rut test be possible?
Harder/stiffer asphalts fail on a regular basis.
Please clarify.
We’ve received your question and a response is forthcoming.
