4 Ways To Save Money With Minor Asphalt Repairs

For asphalt driveways or parking lots, leaving cracks and holes unrepaired can make the asphalt susceptible to crumbling and erosion, resulting in issues that require costlier repairs down the line. To save money on asphalt repairs now and in the future, try these four asphalt repairs for minor problems.

 

Make Minor Repairs

Probably the most common minor asphalt repair is for a pothole. For small potholes, prepare the area by clearing it of rocks and vegetation, then washing it. Make sure there is no standing water in the hole or cracks before you begin.

After preparing the area, you can start filling the pothole with a pothole patch. Cover the area until it stands at about 1 and ½ inches above the surface of the surrounding asphalt, then tamp it down with a tamper, or drive over a piece of plywood set over the top.

Tamp the patch down until it is level with the rest of the area and very compact. When the area is dry, you can then use a hand grinder to make the edge of the new asphalt flush with the old, or, while it is still drying, you can use crack repair around the edge, blending with a spreader.

Before sealing the new pavement, do not turn on this spot for 2 to 3 weeks.

 

Drain Problems

Due to erosion and standing water, asphalt around the drains may begin cracking or deteriorating over time or after a freeze.

To repair minor cracks and chips, mark a square around the drain with marking paint. With a pickaxe, break apart the asphalt in the square and remove the debris. Note that if the foundation underneath the asphalt is compromised, this is no longer a minor repair.

Using a pothole patch, fill the area around the drain with the patch, tamping it down every two inches until it is level with the rest of the surface. You can blend this patch with a grinder or crack repair before sealing the surface.

 

Crocodile Cracks

These kinds of cracks appear due to repeated pressure that can’t be supported by the foundation. Water seeping into the cracks may worsen them.

To repair minor crocodile cracks, clean the area of rocks and debris with a tough broom and make sure there are no loose stones nearby to compromise the fix.

Using Gator-Patch or another brand of crack repair, apply the fix to the surface and use a squeegee or spreader to smooth out the patch into a thin layer. Work the material into the cracks by changing directions.

Let it cure before applying the second coat and the seal coat.

 

Chemical Spills or Stains

Whether from oil spills or other harsh chemicals, asphalt can become stained. For a small stain or spill, begin by drying up any active liquid by spreading kitty litter over the top, stomping it down, and letting it sit overnight.

The next day, sweep up the kitty litter and dispose of it. Then, saturate the area with Dawn dish soap and scrub it into the spot with a tough brush or broom. After scrubbing it into the pavement, wash the area clean with the hose. Repeat as necessary.

Chipseal, Gravel and Aggregate: Same or Different?

Chipseal, gravel, and aggregate are 3 excellent options for keeping a firm ground and building sturdy foundations. But, as anyone who has poured the wrong kinds of rocks into a driveway, drainage field, or pool can tell you, the end results can be devastating if you use the wrong time.

Some differences are subtle, with aesthetics and traffic quality sticking out the most. Some thing just feel better. What’s more important is when you use the wrong material.

Here are your best uses for chipseal, gravel, and aggregate. Know their potential and tailor their benefits for your projects with safety, efficiency, and convenience in mind.

What Is Chipseal Best For?

Chipseal is asphalt that goes through a few processes for the final product. A thin layer of heated asphalt is sprayed on a surface, and then smaller chips of aggregate are added on top. A compactor follows, pushing the chips into place and making their positions more uniform.

After compacting, the chipseal needs to be swept or lightly bugged to remove excess chips. This isn’t a heavy, firm buffing that yanks the chips and scrapes up the cooling asphalt–it’s just enough to remove pieces that aren’t firmly stuck to the project.

Chipseal is great for roads, and it’s 1/4th or 1/5th more affordable than standard asphalt spreading techniques, with a life extension of about 5 to 7 years according to the Department of Transportation.

If you’re repairing a road and need a maintenance plan for anything that has general use traffic, chipseal is a great option. It’s all about correction, preservation, and maintenance.

What Is Gravel Best For?

For people who aren’t used to foundation and paving materials, everything is gravel. It has become a general term, but if you want to avoid buying the wrong kind of rocks, stones, or crumbly bits–whatever you call them in your head–it’s time to look at gravel specifics.

Gravel is measured by its particle size, or the size of the materials in the gravel pack you buy. There are two scales to keep in mind:

Udden-Wentworth Scale

  • Granular – 2–4 mm or 0.079–0.157 inches
  • Pebble – 4–64 mm or 0.2–2.5 in

ISO 14688

  • Fine – 2.0 to 6.3 mm
  • Medium – 6.3 to 20 mm
  • Coarse 20 to 63 mm

Gravel is best used for walking paths, driveways, or if you want the rolling, smaller rock features in your hardscaping. It’s easy to walk on, provides decent grip for parking areas, and is easy to replace.

What Is Aggregate Best For?

Aggregate is a combination of different materials. In most products, it means having coarse and medium grains mixed together.

The size isn’t the only difference–different aggregate packs can include different material types. Sand, crushed stone, recycled concrete, slag, and gravel can be included. Aggregate may combine both of the previous materials and add a bit more.

It’s important to know what kind of aggregate you’re using. For foundations where standard rocks are fine as long as the proper filler is involved, you can use any type you want. If you can’t find a supply for a specific, single pack of materials, you might want to find an aggregate supplier that delivers a close enough mixture.

How do you find out? Along with reading the packaging, ask the supplier. Some people will ask where the aggregate comes from, such as a specific quarry or recycled from another construction project. You might even figure out if they can source the actual materials you need, or guarantee a close enough mix.
