Section 306 requires an FDR mix with 100% of the material passing the 2‐inch sieve, but the specified pulverizing equipment does not possess a mechanism that produces this.
Standard construction equipment can produce a mix with a maximum 3‐inch material size, so we request that the Government change the material specifications for the FDR mix to allow for 100% of the material passing the 3‐inch sieve and 95% of the material passing the 2‐ inch sieve, since these are the requirements
Caltrans uses.
This will be addressed under Amendment
A002.

Subsection 306.09 requires foamed asphalt to be applied when the surface and air temperatures in the shade are at least 50°F.
Given the location of this project and typical weather conditions in the area, this requirement can significantly reduce the potential working window for FDR‐FA on any given day. Would the Government consider removing the phrase “in the shade” from the specifications and/or reducing the minimum air temperature to 45°F, as specified in the ARRA
Recommended Construction Guidelines for FDR using Bituminous Stabilization?
This will be addressed under Amendment
A002.
