![]() ![]() Let’s take a look at why you can put concrete over asphalt, and why it’s a great option. You can also pour new asphalt over old asphalt, however, concrete is a better choice. Typically, builders power-wash the surface to both clean it, smooth out the asphalt, and make the concrete stick to the asphalt more easily. Homes with driveways intended for many large vehicles, however, the asphalt must be 4” or more to support up to 10” of concrete.īefore you can pour concrete over asphalt, you must first soak the asphalt with water. Asphalt is only suitable as a driveway base if it is at least between 2” and 4” thick for residences. The first one is the development of a decision tree for the project selection of a rehabilitation of this kind. You can put concrete over asphalt, and it is a great choice as a driveway base for residential homes. Abstract This report presents the research undertaken within two areas of study of thin asphalt concrete (AC) overlays to rehabilitate continuously reinforced concrete pavements (CRCP). Many builders come across asphalt that is already installed, or are considering installing it themselves, and wonder if it is suitable to pour concrete over. The asphalt technique involves the installation of a waterproof membrane with a layer of hot mix asphalt (HMA). Two types of protective waterproofing to consider for a new deck may be: an asphalt overlay or a thin polymer overlay. ![]() One of the most important parts of putting in concrete is what material lies beneath it. Over time, they can penetrate through the concrete deck and corrode rebar, resulting in damage of the structure. Installing concrete walkways, sidewalks, and driveways is par for the course for many building owners, but it comes with many questions.
