Smooth transitions are necessary to ensure the desired ride for the traveling public. Transitions are used within projects as new pavement approaches a bridge to avoid adding unnecessary dead load on the bridge. As roadways pass beneath bridges, transitions are used to avoid encroaching on the existing vertical clearance.
Step 7: Butt Joints and Transitions When asphalt connect to existing driveways, parking lots, or roads, a smooth transition is needed. The areas where old asphalt meets the asphalt or concrete driveway, butt joints make the transition a smooth one.
Asphalt driveways are a great alternative to concrete driveways when it comes to cost and a great alternative when it comes to gravel driveways when it comes to a solid surface. But when installing a new asphalt driveway, the transitions, meaning where the asphalt meets the garage floor, sidewalks and the street should be a smooth transition.

Step 7: Butt Joints and Transitions . It is very rare to install an asphalt surface that does not connect to existing driveways, roadways or parking lots. As such, asphalt-paving contractors must find a way to smooth the transition from old surface to new. Butt joints are areas where old asphalt or concrete meets new asphalt pavement.
A.: You won't be able to transfer load directly from a concrete slab to a flexible pavement. If you're stuck with an asphalt parking lot, the best approach is to pave a concrete apron around the building, with a slope that will ensure adequate drainage away from the building. Thoroughly compact the subgrade and base material adjacent to the ...

Jun-Feng Su, in Eco-Efficient Pavement Construction Materials, 2020. 11.1 Introduction. Asphalt concrete is one of the most common types of pavement surface materials used in the world. It is a porous material made at a very high temperature of about 180°C that consists of mixture of asphalt binder (bitumen), aggregate particles, and air voids.
1) Projects where asphalt concrete is only used to transition pavement or structure modification or replacement to existing pavement. Medium Traffic project: Use a 448 Type 1 surface course with PG 64-22 for surface and intermediate courses of asphalt concrete and a …
Bonded Concrete Overlays of Asphalt Pavements (BCOA) 2 1. Introduction Bonded concrete overlays of asphalt (BCOA) pavements are typically between 3 to 6 inches thick. The bond between the asphalt and the concrete is critical to ensure that that the pavement behaves as one structure, especially for very thin concrete overlays. This monolithic ...

Asphalt and Concreted Pavements. 3. Apply a joint adhesive to the face of the concrete and then pave the hot mix asphalt against it. The joint adhesive was developed to be applied to cold paving joints to help reduce water infiltration. It has a higher viscosity than a normal hot pour sealant, which allows a thicker layer to be applied to the ...

An asphalt or concrete pavement should be milled to remove distressed layers of material, make crown corrections, maintain curb height or vertical clearance, scarify existing surface, correct surface profil, remove e asphalt overlays, remove distressed pavement near joints, or provide a pavement transition.
This transition should be smooth as well, avoiding dangerous trip hazards. Concrete transitions onto the street: When it comes to the transition from the street onto the asphalt, just like the garage, the sub-grade should be excavated down equivalent to the thickness of concrete that's being installed. This transition should be smooth as well.
