9 The notes on the bearing drawing calls for a min/max shear modulus of 85/175 psi with a hardness of 70. We can’t achieve that. Per the AASHTO design manual 70 duro falls into the 200-

300 psi range. Will 70 duro with a psi range of 200-300 be required or will an alternate be allowed?

Providing a 60 durometer shore A scale elastomer with a shear modulus between 130 to 175 psi is acceptable.

10 Will 14GA stainless steel for the slider for the bearing be acceptable?

14 GA stainless steel is acceptable.
