Not at all. I think this is interesting. My mind went immediately to MOD Modulus of Elasticity when you said my job is to break things. The first design job I had was working for a portable basketball system company called Lifetime products. Part of my on the job training was to help in testing. I got to break stuff too! It can be fun.

Somewhat related question: Roughly ten years ago I worked with an engineer out of Canada who was developing a road pavement material made from recycled polymers. The idea was that a pavement made from a polymer blend would not allow water to stick and freeze. This would also reduce maintenance as de icing products would not effect it and cause pot holing. Ever heard of it?

How's this for a snoozer topic?

Not sure if you have heard of the SHRP program...by Wisconsin getting involved with this program, we have moved into using the polymer modified binders, if the polymers that are used are recycled, that i would not know. Have not heard of the particular method you speak of.

Will have to get back to this later

I hadn't heard about the SHRP program but I just looked it up. I'm checking it out . . .

I have been contacted in the past from your own DOT, mostly from a student attending one of your universities, looking for information and is working for the DOT for the summer. They usually end up asking about our Combined State Binder Group and tell me that the concept is interesting and leave it at that.
I've also looked up information on how Texas DOT compares to Wisconsin...like always some areas you are beyond us and others you seem to be behind.
Most of the United States have jumped on the SHRP wagon since the Feds made it known that they were using it as a guide line.
We have a few suppliers that only supply streaght binder (non-modified) but most all of the supplieers to the Wisconsin DOT projects ship polymer modified. The one thing that all the suppliers have mentioned is that ever since we went to the Performance Graded (PG) binders, they have seen a better relationship between them and the state. The PG grades is one thing that developed from the SHRP program.
