A Homeowner's Guide To Asphalt

Asphalt is a flexible paving surface made of crushed stone, sand, and a petroleum-based binder that holds the mix together. For most driveways and small paved areas it is a practical, durable choice that can be repaired, resurfaced, and sealed over its service life. Bruck Construction installs asphalt for homeowners, including driveway paving and repairs.

What asphalt is made of

Hot-mix asphalt, the type used on most driveways and parking areas, combines aggregate with asphalt binder. Aggregate is the crushed stone and sand in the mix. The binder is a dark, sticky material refined from crude oil, and it coats the aggregate and holds it together. The proportions of stone, sand, and binder control how the finished surface handles weight, heat, and water.

How asphalt is installed

A typical installation starts with excavation to the proper depth, followed by grading and compacting the subgrade, which is the native soil beneath the pavement. Next, a base layer of crushed stone is spread and compacted to create a stable platform. The asphalt is then placed hot, spread to the specified thickness, and rolled with heavy compaction equipment while it is still workable. Edges are finished so that water drains away from the surface.

Why the base matters more than the top

Most asphalt failures begin below the surface. If the subgrade is soft or the base is too thin, the pavement will flex under load and crack. A surface placed on a sound base can last much longer than one placed over poor preparation. For this reason, a written estimate should describe the excavation and base work as clearly as the asphalt itself.

Sealcoating protects the surface

Sealcoating is a thin protective coat applied over asphalt to shield it from sun, water, and oil. The sealer is coal tar or asphalt emulsion, chosen for each job and recommended in the written estimate. Sealcoating does not repair cracks or structural problems, but it helps slow surface wear when it is applied to sound pavement at the right time.

Cracks and potholes: when to repair

Small cracks should be filled before water gets underneath them. Water that enters a crack freezes and thaws through the Ohio winter, and each expansion widens the crack and loosens the base. Potholes usually mean water has already reached the base. They are generally cut out, the base is repaired, and the area is patched rather than simply filled on top.

Asphalt compared with concrete

Asphalt and concrete each have a place in a homeowner's plan. Asphalt is flexible, can be repaired in sections, and is installed hot and smooth. Concrete is rigid, holds its shape well, and offers a range of finish options. The right choice depends on your site, drainage, and how the surface will be used. Our guide to concrete explains what to expect from that material.

Maintaining asphalt over time

Keep the surface clear of oil and fuel spills, which soften the binder. Repair cracks promptly, keep drainage moving away from the edges, and avoid heavy turning on new asphalt while it is still curing. Routine crack filling combined with a sealcoat applied at the right time is the most common maintenance plan for a residential driveway.

Warranty and the written estimate

Bruck provides a 1-year guarantee on all asphalt and concrete work. Your written estimate should list the scope of the job, the materials, the sealer type if sealcoating is included, and the schedule, so you know exactly what is being done before work starts.

Frequently asked questions

How long does an asphalt driveway last?

Service life depends on the base, the climate, drainage, traffic, and maintenance. Asphalt with a sound base that receives regular crack filling and sealing can serve for many years. Ask your estimator what to expect for your specific site.

Can asphalt be installed over an old driveway?

In some cases, an existing asphalt surface can be milled, meaning the top layer is ground off, and then resurfaced rather than fully removed. Whether that is a good option depends on the condition of the base and the drainage. An on-site evaluation is the best way to decide.

Is sealcoating necessary?

Sealcoating is optional, but it is a common way to protect the surface from sun, water, and oil. Your estimator can recommend whether it makes sense for your pavement and when it should be applied.
