Section 409.05 Micro Surfacing Equipment allows for truck mounted and continuous machines for placement of Type 3 Micro Surfacing. With the project having over 40 miles of continuous roadways in an effort to mitigate the transverse joints which would be in excess of 400 if truck mounted units were allowed would it not be in the best interest of the FHWA to specify a continuous run machine for the Type 3 Micro Surfacing. Previous projects such as CA NPS YOSE 2018 (1) Pavement Preservation Yosemite required it on a similar project

At this time, we will not be modifying the requirements of Subsection 409.05. Bid accordingly.

9 X

Section 105.04 lists locations that can not be used for staging or storing and stockpiling of material does the FHWA have a list of stockpile locations that can be used on this project?

All of the locations listed in Subsection

105.04 are not restricted. The list of restricted areas are shown in Subsections 105.04(a) and (b). See paragraphs 1 through 3 for additional information.

Section 409 – Microsurfacing does not indicate the use of self‐loading machines as is typically found on projects where Type III material is specified and when we see similar quantities.

There was a previous question regarding use of self‐loading machines and the response said to bid accordingly, meaning self‐loading machines will not be required. The concern still, is overall quality for the Owner, specifically the large number of joints left by using equipment that isn’t self‐loading. ISSA A143 is referenced throughout the specials and standards (see attached – transverse joints). ISSA A143, Section 6. Equipment, Number 6.2 “Mixing Equipment,” talks about specifying continuous machinery to minimize transverse joints. It also specifies in Section 11, Number 11.3 “Joints,” that transverse joints shall have no more than a

0.25 inches difference in elevation when measure by placing a 10 ft. straight edge over the joint and measuring the elevation difference. Section 409.10 “Application,” paragraph seven (7), states that ridges or bumps in transverse joints shall be removed from the finished surface. Should bidders assume that this specification will be in force?

Bid according to the contract requirements.

The government will enforce the contract requirements.
