Roadside grading

“

- [Instructor] Roadside grading for component roads is another powerful design tool that designers can take advantage of when designing roadways. So let's zoom in to this component road. When I click on it notice here in the stack it says Grading Limit is 25 feet, so the grading along this component road you can kind of see here the transparency of the grading, going from the sidewalk down to a natural grade at 25 feet. Notice here the grading is going from the back of the walk down to a natural grade or existing conditions and the set width is 25 feet, but typically that doesn't happen in the real world, it's actually varying throughout your site. You're trying to hold a constant slope so this will never be a straight line unless you're trying not to encroach into somebody else's property. So let's change this. I'm going to change this to a Fixed Slope. And here it says Grading Limit is 25 feet, Cut Slope 10 to one, Fill Slope is, I'm going to change that to 4 to one for my Cut and four to one for my Fill. So as you can see that's more accurately depicting what would happen in the real world if your building a road. You're going to be holding a constant slope and it's going to create this kind of imaginary line along here. Now you do have the capabilities to change the different slopes at different areas or different sides of the road. So for example, if I click on this side of the road twice, here I can say okay on this side of the road, I'm going to say it's actually five to one, but on this side of the road it's actually going to be three to one. Maybe we're restricted on the width 'cause we're adjacent to another property or development. So as you can see here, what is actually happening. Let's also assign a material to this grading. Right now there's no material assigned. So we're going to say, we're going to click in here, and say for Fill we can use the Grass, and hit Enter. Same thing here, for fill conditions material, use grass, hit Enter, there you go. As you can see we got a nice green area along our road. But what happens if you have an area where it needs to be three to one, and then it jumps to six to one. You can actually split this roadside grading by clicking on this roadside grading on the right side here, and I'm going to say Split Grading, and I place it right here. So on this side it's actually three to one, but on this side I'm actually going to assign six to one, change that to six to one also. There we go, as you can see the difference, but I'm also going to need a transition zone because we got an area here, it's happening from three to one to six to one so let's create a transition zone. So I'm going to click on this area, right-click and say Add Transition. Here we go, and the station, I'm going to say Station 250 for the value. There it is, okay, and there is my transition zone between a three to one side slope grading to a six to one. There we go, as you can see. And I can use different materials on different sides of the road. So if I click on this side I can use something different, maybe this Border Stone. So I hit Enter, there we go, as you can see. I can add another transition zone. So I'm going to split this, Split Grading, put the right there, double-click. So here I've actually split the grading again, I'm going to add a transition but first I need to change the slopes between these two grading so here I'm going to put this at three to one, three to one, put it in the stack. And then I'm going to right-click and say Add Transition, right there, I can type in a Station if I need to. So there's my transition zone between the difference side slopes of the component road. So with the roadside grading features, designers can control the limit of construction for the component roads, and help balance the cut/fill factors for the road.
