A: We will let you know once we perform a survey. If it needs to be replaced, all of the current asphalt will be removed and properly discarded of. We will ensure that there is a proper base material added to ensure a well-built driveway. If we discover any wet or soft areas in the sub base, or the soil layers, they will be removed and filled in with solid materials such as gravel until a solid base is installed. All paving work will be completed with proper asphalt paving machines and proper-weight vibratory rollers. We will then install another layer of asphalt over the compacted asphalt. This compacted thickness is the final thickness of the finished product.
