Mill and Overlay Parameters

I am trying to overlay a large area,I have a design profile grade that I must use. I need the new edge of the overlay pavement to be 2" above the existing as long as the pavement cross slope is between 1% to 1.5% . If the slope goes above or below the min or max I need it to take the min or max. If I use the overlaymillandlevel2 I am unable to get it to use the overlay thickness since i am using a profile. Does anyone know how I can do this?

 

thanks

if you have to be 2" at the edge then you'll need to find your profile from that parameter, right?

I can only use the profile if the cross slope falls within the 1% to 1.5%. If the crossslope falls outside the min max with 2" at the edge of pavement then the 2" will vary and the min or max slope will control. If that makes sense.

thanks

It may take more than one pass.
I would start with 2" overlay Match slope. Look at the sections and determine where to break it up? guessin here

Thanks for the quick replies Joe, I am trying to think outside the box to come up with a way to do this. If I have any luck I will post the solution.

thanks

Good luck Vern

Let me know how it goes. I know the OM2 can get frustrating

This subassembly has been confirmed as defective. See the thread below:

I'm confused here.  You have a design profile at the crown or at the edges?  OM&L2 has an optional profile at the center but I don't see anything for the edge elevations. 

 

I'm wondering if OverlayWidenFromCurb would work.  Use two generic links to move over to the existing edge of pavement, then up 2" to the attachment point for the overlay sub.  If you use the profile option then you could check the calculated slopes in your corridor then adjust the profile as required.

I have a profile grade at the centerline. I tried the OverlayWidenFromCurb assembly but I don't see how to connect it to profile. All I see is set a distance above the existing surface. I have tried everything I can think of and still can't get the final product I need. Hopefully someone has an idea that will work. Thanks for the suggestions, I am willing to try anything at the moment.

Here's the parameter list I have for OWFCurb.  I don't see anything about a distance above surface.

When I built a corridor using this I have a targeting option there for the inside edge profile of the overlay.

I've read through this thread several times and I'm getting even more confused.  You start from an profile elevation at the inside edge and you have a fixed outside thickness of 2"  If the slope between those two points is 1.25% plus or minus 0.25% then you're OK, otherwise the outside thickness must change - correct?  I'm not sure why you say that you would not use the profile in that case.

 

We may need a sketch here.

Crown Height is the term I should have used. I need to connect it to the centerline design profile. I dont get the same variables as you. I am using 2011 so mine appear different.

thanks

Hear is a sketch, I hope this helps.... I dont think I am explaining myself vary well. Please bear with me.

Don't worry about it.  I'm working on some early Christmas cheer here, so there isn't much you can say to annoy me today.

 

I've got an idea for using generic links and some conditional test subs to do this, but it needs to percolate in my head for a while.  Are your lane widths fixed or variable offsets?

yes, lane widths are fixed. thanks for all your help. Enjoy the rest of your evening.

wouldn't the height above be the profile of the edge?
Thank you

If the lane widths are always fixed then it's easy.

 

Create a level horizontal generic link from the Assembly attachment point that is the CL profile elevation, out to the lane width offset, and test that location with the Conditional Cut/Fill subassembly for the Fill depth range that will effect your desired cross slope range.

I think this will work. I will mark as solution accepted as soon as I give it a try tomorrow at the office. Thanks to everyone for all the suggestions

It looks like this isn't going to work.  I cannot get the Overlay sub to work when it is inserted after a Conditional sub - no idea of why.

I am not having any luck either. I am not able to get a slope from a link to marked point in 2011. Maybe it will work in a newer version.

Thanks to everyone for the ideas to try.

Merry Christmas
