I've used the OverlayWidenMatchSlope1 subassembly to widen a new travel lane using the existing carriageway crossfall then I try to create another lane using the same assemble following the same slope but the insert point always starts on the existing ground rather the new levels from the first new widening lane.
View 3 RepliesIm using civil 3d UKIE 64bit, having a serious problem with adding a lane widening to an offset alignment. It is a straight alignment approx 200m length, but when i enter the parameters that is asked, at the end it says no solution!
View 2 Replies View RelatedI am having a problem with an overlay and widening C3D 2012 project. The sub assembly I have chosen is processing with the corridor datum surface cutting into the existing road surface, as would happen with a “milling” section (which I don’t want), I need it to overlay onto the existing surface only, with a nominal minimum thickness of 4” . I think this sub assembly is drawing the datum surface from the datum point of the widening on one side to the datum point of the widening on the other side, not sampling the "bottom" of the overlay surface.
See attached screen shot. Also attached are screen shots for some of the sub assembly and corridor parameters for my current settings. I am using the “overlaywidenmatchslope1” and “basicsideslopecutditch” subassemblies.
I have tried changing the sample point offsets and the insert point offsets without fixing this problem. I have not added any additional alignments for saw-cutting yet as I am trying to keep it simple until I get the assembly to process correctly with a fixed width.
I looked at trying the “overlaywidenmatchslope2” subassembly, but it is for non-crowned roads and would not work for this project. Are some of my parameters wrong? Is there another subassembly that I should be using?
Is it possible to make the widening get the exact offset to the spiral / clothoid. All I get is a linear line as shown in the picture.
View 6 Replies View RelatedI have created a widening then created an 11-foot offset from the widening for some reason I cannot create a 22-foot offset or an d11-foot from the first offset. I can go as high as 22.5 but no more. There are no curves in the alignment only linear tapers. why I cant get to 22-feet?

I am overlaying and widening an existing road, however the assembly is not behaving as I would like it too. Here is the cross section below, the widening, overlay and day lighting portions appear correct, how the Datum surface is off.
DATUM SURFACE - The datum surface is not following the existing ground in between the two road widening pavement portions. You can see the datum surface as a red line connecting the two paved widening below the existing crown of the road. I would expect the datum surface to follow bottom links of the overlay as well up through the crown, but this is not the case.
EARTHWORKS CUT/FILL SURFACE - The earthworks surface shows that the area between the existing crown and the unexpected datum link is being calculated cut/fill (cut presumably) which it shouldn't be.
ASSEMBLY BEING USED: Perhaps I am misusing the subassemblies, or link codes need to be modified.
Having issue with the intersection tool for a road widening with turn lane with new roadway intersection. Not repaving entire existing roadway, sawcutting 2' into lane then paving new turn lane. Do most people use intersection tool for road widening, or is it strictly used for new roadways.

I'm working on a windfarm access road (5m wide with widening at bends to 8m) and I need to identify the areas of widening.
I've got the centreline alignment and created the 2.5m offsets to each side. I have also created widening on the insides of the bends using the widening tools and used a linear taper at entry and exit. I now need to hatch up the portions where the road has been widened to demonstrate compliance with the specification and the only easy way I can see is to export to autocad and use the hatch tools (not tried to hatch between alignments).
Whilst this works it isn't dynamic so if the alignment is adjusted the widening alignments are also moved but the hatching remains.

there has used a non-AASHTO curve widening formula to calculate automatic curve widening for an alignment? I'm trying to use our Agency curve widening formula which is a function of curve radius and central angle.
I'm not sure if it is even possible to use the central angle of the curve for calculating widening, or how one would go about using a non-AASHTO CW formula.
Attached is the curve widening formula that needs to be used. L will be a constant here.

I am building an assembly for a shoulder widening. the sholder is 5' paved plus 5' stabalized tying to existing grade at a 4:1 slope. The two shoulder sections are showing up in the cross section but the tie-down is not. I have checked the target and it is set properly to the existing ground.
See below.
I need to create an assembly where the median width varies , I already created the alignment, profile,corridor,section with the design level. Also I have created the assembly with fix width. Now in the middle of my road the median is getting bigger ,Its possible to link the median with a polyline or another alignment were it change the width ?
View 4 Replies View RelatedAlthout I have created the widening on my aliment and used a designer critery on my corridor, I can't achieve that the corridor use the widenig on the curves.
I need that the corridor generate the widening on the curves, I can't stake the corridor without widening.
Please see attached.
Superelevation curve criteria specifies axis of rotation but the assembly does not contain pivots.
okay i got this Before , just when i wanted to change in the Super Elevation Wizard , to outside lane rotation , i recently used AOR type , but yet no luck. also in my profile the super elevation the Cross slop Band : i always no matter what a rotation about center line.
I'm looking to make an assembly to follow the crown of the existing roadway which is to be milled and overlayed. In addition to being milled and overlayed there will be a curb bumpout which will be full depth pavement. The roadway does not hold a constant crown at 2%, it varies which is why I would like it to mimic the existing roadway cross slope. What would be the best way to go about making an assembly to model this. I have attached an image so that you may get an idea of the situation. I have a curb gutter line which I would like the assembly to target in both width and elevation. The single slanted hatch is mill and overlay and the double slanted hatch is full depth pavement (widening).

I tried to import the Lane Toward Crown subassembly to my Lanes tab, but the import function looks for *.pkt files and all I have in the Stock Subassemblies folder are *.vb files.
How can I get the *.pkt files?

View 4 Replies View RelatedI have an "ultimate" profile that has be set for a proposed roadway the first 1500' of the roadway will be constructed at this final profile while the last 900' will be constructed for an interim design not at the full depth pavement. So my typical for the final is 9.25 inch of pavement over 14" of stone and the interim is 4" over the same 14" of stone when we transition from the 4" to the 9.25" we are using a 20:1 taper the question is how to model this taper condition and have you had any success.
View 1 Replies View RelatedIn my corridor I have used superelevation. In a horizontal curve which has a cross slope of 4.5%, I have an intersection. To allow for a smoother ride through a few lanes in the intersection I want to change the cross slope from 4.5% to 1%. I was planning on doing this by using a Outside Lane Elevation Method of a Profile. However, it appears that my super has precedence over my profile. Is there are way to make this work?

View 3 Replies View Related I'm attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.
I watched the cul-de-sac placewhere and I seem to missing some functionality shown. Specifically the ability to link a transition lane to an alignment and profile via corridor properties>logical name>no width shown as the placewhere shows?

Without automation development, what is the procedure to get a digital record of the existing road lane slope?
I recommend the following:
1
Use the OverlayWidenMatchSlope1 rehab subassembly to build a corridor, targeting the existing road surface
2
Make a report using Corridor > Feature Line Report, reporting the Links to get the slope
Am I correct?
I have an assembly that contains a basic lane tranisition with a retaining wall next to the road. I have created an alignment for the lane transition to follow but the wall stays in the same place. Shouldn't the wall move with the lane transition? The sub assembly are inserted connecting each other. what am I missing?

For some reason I cant seem to target an offset alignment layout profile with my corridor lane assembly. I can target the existing the existing groundprofile with the same offset alignment, but the layout profile when targetted does not change the lane in my cross sections. I can do this with civil 3d 2010, but not 2012. I have tried other lane sub-assemblies and it doesn't make a difference.

i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.
View 9 Replies View RelatedWith using superelevation wizard in Civil 3d 2012, changing the lane width is not affecting the resulted values of transion length and run-off length, Is that correct ? ( as civil is using standerd AASHTO tables which assume that lane width typically is 3.6m )
Also, There is only 2 tables for 2-lanes and 4-lanes roadway, Is it for total road width or for one directon only, and what about different no. of lanes ?
