When you want to update your concrete to an asphalt option, be sure to do it the right way. Read why it’s better to remove a concrete driveway before laying asphalt
Asphalt driveway paving is a laborious task in itself. However, it can be made far more tricky if the previously existing concrete is not removed beforehand. It’s not a question of whether or not you can. It is instead a question of “should you?”. It will impact not only the durability but also the longevity of your driveway. Generally speaking, it is highly recommended that you remove the existing concrete first before laying down a new layer. Read on to see why you should invest in the paving of your property.
Difference In Sub-base
The largest factor that can be your downfall is the preparation of the site. Usually, the area is adequately prepared to receive surface treatment correctly. This ensures proper, even adhesion and setting can take place. With concrete, the site is not ready in the same way. Instead, strength is increased by laying a thicker slab over the area. Because of this, any imperfections or faults in the ground below can cause weakness in the base. This issue will remain unseen without proper surface preparation. If something is wrong with either of these previous layers, it will show through and weaken the new addition. Expansion and movement below that can develop into cracks above will cause issues all along the paved area, expensive to repair.
Creates Imperfections
While the initial result of not digging up the previously existing concrete may be acceptable, the truth will show through in time. The cheaper alternative that seems like a good quick-fix can cost far more in the long run. You can be sure that you won’t create even more imp[erfections in the new layer with proper ground preparation. As the older surface may have warped or shifted over time, weak points may cause erosion or collapse. Layering on top of this means not only can the material not settle correctly, but it will be further weakened by whatever lies below. Taking away the old and adequately preparing the new layer’s surface ensures that no imperfections or foreseen damages can occur.
While the more comfortable option may seem best, remember that a problem covered up is still a problem to be faced down the road.
