Inquiry #2: Regarding the Armorguard barrier. On pages SC-6 and SC-9 of the stage construction and traffic handling plan it shows a run of Armorguard and pinned k-rail on each side of the workzone. Per the Armorguard manual, there is 6.5' deflection when impacted. Being that the workzone is so narrow, is there any way to anchor the Armorguard in the same fashion as the k-rail since this appears to be a minimum deflection area?

Response #2:The AmorGuard cannot be staked to the roadway to minimize deflection. It is not designed or approved that way either at Caltrans or FHWA. If the Armorguard is being connected to concrete barrier via the methods provided by the manufacturer/distributor, the deflection near the connection points should not be as great as a standalone ArmorGuard system.

Inquiry #3: The spec calls for Class 4 Subbase which is a reserved section of the Standard Spec. We were unable to locate the product in the project specials. Is Caltrans able to include or clarify the spec for the Class 4 Subbase?
