Inquiry #11: Spec section 25-1.02D states “Obtain Class 5 AS material from a commercial location or material found on site.” Further, the gradation chart indicates that the majority of the material is required to be ½” to ¾’ with only 2% passing the No. 200 sieve. Based on the geotechnical report and borings available, it appears that the onsite materials are clays, sands and silts and will not meet this spec. Due to the large quantity of Class 5 AS required for this project, obtaining material from a commercial location would add considerable cost to project. Please consider revising the gradation and R-Value requirements to match the previous segment of Rte11/125/905 (Contract 11-288814) which required 100 % passing of the 6 Sieve and R-value greater than 10.

Inquiry #14: With regard to Special Provisions Section 25-1.02D, along with a review of the GDR included in the Information Handout, it does not seem that the gradation requirements of the Class V AS align with the intention of utilizing onsite soils. The GDR indicates that “Class V Aggregate Sub-base materials is defined as material possessing a Resistance-value (R-value) greater than 25 and a Plasticity Index (PI) of less than 12. Alternatively, a Sand Equivalent (SE) of greater than or equal to 15 may be used to qualify the material in lieu of the R-value and PI.” The gradations provided in Section 25-1.02D would lend itself to a non-plastic, free-draining rock with virtually no fines and would not feasibly be generated onsite. Please provide clarification if the gradations included in Section 25-1.02D are the intended requirements for the Class V Subbase, and if so, where in the alignment is that material to be found?
