ASTM A36 vrs ASTM A615
ASTM A36 vrs ASTM A615
(OP)
I am on a project which specifies the following for load transfer dowels in a junction slab (Basically the slab that prevents overturning when a vehicle hits a traffic railing mounted on a MSE Wall, the dowels transfer the load at expansion joints):
Dowel Load transfer devices will be ASTM A 36 smooth round bar and hot dipped galvanized.
And the certification for that bar submitted states the following:
1" Round Grade 60/A706
ASTM A615M-12 GR 60/A706 CE.50 Max / AASHTO M31-07
Can this be substituted for A 36?
During my investigation it appears the only different is that A615 Grade 60 has a higher yield strength but less ductile.
Thoughts?

A36 is a fairly weak steel. Is that an older spec?
RE: ASTM A36 vrs ASTM A615
It is from the FDOT design standards for 2015.
So essentially the A615 is a better product? Can you comment on the differences?

Abstract
This specification covers deformed and plain carbon-steel bars for concretereinforcements in cut lengths and coils. Materials considered under this specificationare available in Grades 40 [280], 60 [420], and 75 [520]. Steel samples shall be rolledfrom properly identified heats of mold cast or strand cast steel using electric-furnace, basic-oxygen, or open-hearth. Heat analysis shall be performed wherein steelmaterials shall conform to required compositions of carbon, manganese, phosphorus,and sulfur. Steel specimens shall also undergo tensile tests and shall conform torequired values of tensile strength, yield strength, and elongation. Steel samples shallalso undergo deformation test, tension test and bend tests. Final products shall bemarked by a tag.
ASTM A36
1. Scope*
1.1 This specification covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order.

It appears the A615 is a better product.

For doweling purposes, either A615 or A706 is superior to A36

The A307 standard included a Class C which was essentially A36 anchor bolts. So a related question, "Can I use A307-C instead of F1554 Grade 36?"

Thanks everyone for the replies! Super helpful!
