Asphalt Paving Preparation in Lititz, PA (Lancaster County)
The most important aspect of all asphalt pavement installation (and blacktop surface prep) is a solid foundation. When starting a new project, it is vital to have the soil graded properly. If the soil is not stable we remove the unstable soil until we find a solid foundation. When necessary we use a soil stabilization fabric, which prevents soil from coming in contact with the stone.
Once a solid foundation is established, stone is then placed. We recommend a minimum of 6″ of stone on all paving applications. We place the stone with a grader, ensuring proper slope to allow for drainage.
The stone is then compacted with a vibratory roller. We use a jumping-jack tamper to compact the stone wherever the roller cannot get to. It is especially important to use a tamper in front of garage doors to help obtain maximum compaction.
