Why Sand Makes More Sense than De-Icing with Salt

Wednesday, November 26th, 2014

De-Icing with SaltIt’s only November, and we’ve already experienced snowfall and record low temperatures in Maryland. With that said, we could predict a harsh, snowy winter this year. To prepare for a snowstorm, we tend to gather the essentials: milk, toilet paper, bread, and road salt. When our driveways and roads are shoveled and plowed, usually salt is put down to help melt the icy patches. However, have you ever considered using sand instead of de-icing with salt? Though salt has been known to save lives and prevent traffic crashes, it has its dangers.

Road salt can thoroughly damage sidewalks and cause the cement to crack, making the area a hazard even after the ice is melted. In addition, salt poses a huge environmental risk to wildlife as well as humans. Because road salt is unrefined, unlike table salt, it contains minerals and chemicals that assist with the de-icing process. When the salt and chemicals eventually runoff into streams and lakes, it creates an unbalanced salt ratio and decreases oxygen levels. This, in turn, has harmful effects on wild animals and plants living in the surrounding areas.

Salt can also be damaging to you as well as your pets. Excessive salt can enter our source for drinking water. In some cases, city water supplies have had to be shut down because of the amount of salt present. Drinking the water contaminated with these harmful chemicals can have very negative effects on your health. In addition to your health, salt can also affect the health of your pets. The large pieces of rock salt could become wedged between paws, or harm their digestion systems if accidentally consumed.

To avoid these problems, consider using sand instead of salt. While sand doesn’t exactly melt the ice, it still provides traction for drivers, walkers, and pets. Take a look at some of the other benefits of using sand instead of salt:

  • It’s a cheaper alternative to salt, which means it can be used more frequently and in more locations
  • It contains no harmful added chemicals
  • It’s composed of smaller grains, which will making walking easier for pets

The only real downfall of sand is that it doesn’t disintegrate, and can buildup on roads and in streams. However, with no harsh chemicals, sand doesn’t pose a huge risk for humans or the environment.

Before you pick up a bag of road salt to prepare for the winter storm, pick up two bags of sand instead. With cheaper materials, you’ll be able to get more for your money, and make your walkway safer for yourself and your family.

Crack Sealing versus Crack Filling

Thursday, July 28th, 2011

Your pavement will eventually fail. It doesn’t matter how well you maintain your paved surface, it will eventually deteriorate and crack. However, how you deal with those cracks will determine how long your pavement will last. Sealing and/or filling cracks in existing pavement is the single the most effective procedure that can be performed to extend pavement’s lifecycle. This will prevent water and other foreign materials – sand, dirt, et.c – from seeping down into the asphalt where it can cause major distress and failures by weakening the base and sub-base.

This article from explains how filling or sealing pavement cracks is the most cost effective way to extend the life of your asphalt pavement.

Crack filling and crack sealing, while similar in nature, offer very different benefits.

Crack filling is less costly and will require less initial investment, but this solution may only be a temporary fix. Once the crack begins to move or expand, the crack filling material will lose its effectiveness and the crack will need to be re-filled. For this reason, crack filling is more effective in milder climates with less temperature change.

Crack filling materials include liquid asphalt, asphalt emulsions and cutbacks.

Crack sealing is a more costly option, but provides a longer life expectancy than crack filling – lasting 8 years or more. Crack sealing – which utilizes a flexible, specially prepared hot pour rubberized sealant – is considered a permanent treatment and is the only effective treatment for active cracks that contract and expand between seasons.

Crack sealing materials include asphalt rubber, rubberized asphalt, low-modulus rubberized asphalt and self-leveling silicone.

So explain your situation and budget to your pavement specialist and come up with a solution that meets your needs and your budget. If you have any questions, contact PTG Enterprises aka My Pavement Guy by calling 410-636-8777 or click here

Why Asphalt Pavement?

Thursday, June 30th, 2011

If you are thinking about having any surface re-paved – driveways, parking lots, roadways, airstrips – asphalt pavement is the way to go. Known for its durability and resilience, asphalt pavement is the best option for most all paved surfaces. If laid properly by a professional pavement company, asphalt pavement should last between 25 and 35 years. But what is asphalt pavement?

This article from explains.

Asphalt pavement is made up of a combination of stone (aggregate), sand, additives and liquid (petroleum) asphalt. This mixture is about 90% aggregate and sand and 10% asphalt. This combination forms a highly durable material that still maintains superior flexibility, allowing the surface to adapt to changing conditions produced by weather and the constantly changing surface beneath it. On top of its superior flexibility, asphalt pavement is also highly resistant to water, making it even more durable.

Steps involved in laying asphalt pavement:

1.    Preparation: Unless the asphalt is being laid over existing asphalt (overlay), it is the preparation of the ground beneath the pavement that is the most influential factor in the life of an asphalt pavement surface. Proper clearing, excavation, ground compaction and base materials require a great deal of expertise. Base materials can be compacted stone and/or an asphalt base with it’s own unique recipe. Regardless, without proper groundwork the life of the paved surface is greatly reduced.

2.    Spray a thin coat of liquid asphalt binder (hot tack) onto the surface using an asphalt distributor. This helps the newly paved surface create a greater bond between it and the surface beneath it.

3.    Lay the asphalt pavement using an asphalt paver and compacted using asphalt rollers.

4.    A minimum of 24 hours is required for the asphalt mix to solidify before it can be used. If enough time is not allowed for solidification, then it will result in poor a quality pavement.

5.    Asphalt maintenance – including cracksealing, pothole patching and sealcoating – can all be used to protect and extend the life of the already long life cycle of asphalt pavement.
