Commentaire
The following are additional commentary from ORBA regarding the tack coat special provision (SP 103S08 – August 2022) for MTO consideration:
1) Section 308.07.01.01 – Would the Ministry be willing to go back to the original wording of “standing water”? – “Surfaces to be tack coated and joint painted shall be free of all standing water and contamination…”?
2) Section 308.07.02.01 – “A sublot lot shall be terminated…for a period of 20 Business Days or more.” Would the Ministry consider giving the contractor the option to request to keep the lot open (i.e., wording similar to OPSS.PROV 313.08.01.02.01.01)?
3) Section 308.07.02.03 – Is the Ministry satisfied with having one pavement core sample, for ISS testing, per application rate on the majority of their projects? At one sample per 400,000 m2 (or roughly 50,000 tonnes of HMA), this will most likely be the case.
4) Section 308.07.02.03 – “…no later than the next Business Day after the completion of the sublot paving for testing for information purposes only.”; “The traffic direction, and lot and sublot numbers shall be clearly…”
5) Section 308.03.04 – Not sure if penetration and oil portion of distillate should be included here for referee testing since they are both reported for information purposes only. Please Clarify!
6) TABLE 2 – When does the range apply? In accordance to Section 308.03.05.01, only if the rate is less than the minimum is it considered rejectable.
