Driveway paving costs around $4,500 on average, but depending on many factors, you could pay anywhere from $2,500 to $6,600 or more. The size of your driveway will usually be the most significant factor, with more square footage increasing your costs. You can expect to pay between $2 and $15 per square foot for paving services. Some other factors that play a role include the following:

• Quality of the materials

• Contractor’s experience and expertise

• Site preparation and grading, if necessary

• Layout of your driveway

Many asphalt companies have experience with tar and chip paving, but not all. The process is unique enough—and not incredibly common enough—that you may have to look around for a tar and chip specialist. However, speaking with a driveway company is a great place to start, especially if they have experience with multiple materials.

The average cost of 1,500 square feet of asphalt ranges from about $10,500 to $22,500, depending on location, thickness, base material, and how accessible the job site is to crews and equipment. Keep in mind that your asphalt material cost may vary depending on its type, ranging from porous asphalt to heated blacktop. Standard asphalt costs $7 to $13 per square foot.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.
