Q: (TC) SECTION 31 32 19.16-6 GEOTEXTILE PART 3.03; JOINTS SUBPARTb.1Please note that a "Minimum" seam strength efficiency of "75 percent" is highlyunlikely when testing is performed in accordance with ASTM D4884. It is morereasonable to expect sixty to sixty-five percent strength retention in seamsmade in a controlled environment such as a fabrication facility or laboratory.Field seam efficiencies normally range from forty to forty-five percent by ASTMD4884. Please research this matter and revise the Specification parametersaccordingly.R: Refer to Addendum No. 7.18. Q: (TC) SECTION 32 11 23- 1-5 AGGREGATE BASE COURSESThe "Aggregate Base Course" section for this Specification omits the use ofgeosynthetics that can be used to improve deformation response of theaggregate base layer, reduce material thickness requirements, improve layerdrainage, reduce undercut and stabilization requirements, increase the servicelife of the roadway, etc. It would be in the best interest of the project Owner toinvestigate the use of geosynthetics in this application to help reduce both initialand long-term roadway costs for their projects.R: Thanks for the information but no changes will be made to the Documents19. Q: (AG) On drawing 05-CS-2 and 4 there is a note calling out a 15' highlandscaped berm yet we cannot find any specifications for landscaping on thisproject, can this please be clarified?
