Vitruvian Infrastructure Phase 1B
4010 Marsh Lane Addison, Texas 75001 
Project Number: 1308B
	

 	Status: Outstanding Overdue	  	
Subject	Asphalt Connector road (permanent)  	
Reason Code   	 None 	 
Question	 The permanent asphalt connector road as shown on sheet 7 of the phasing plan and sheet 24 of the paving plan shows to have 6" of lime stabilized under 4" of flexible base.
With this being such a small area (298 SY), could we use flexible base in lou of lime stabilized if proctors and densities are taken? Please advise if this would be acceptable for this
particular asphalt connector road. 	
Proposed Solution	 NTC proposed to use flexible base in lou of lime stabilized for the asphalt connector road by the Garden Oak Apartments.

Memo	 I think just omitting the lime stabilization is this area is sufficient. We do need to include reducing the quantity of lime stabilization in the change order by this area (298
sy).

Memo	 I disagree. That small connector road in on private property and may be there for some time. We do not want to reduce the quality of the section just for convenience. The cost
of substituting 4" of flexible base for the lime stabilization is very small and is more convenient.
