Spring has sprung! And with it comes warmer temperatures, flowers… and potholes. But how do potholes form and why are they more present in the spring?
Potholes are holes in the road that vary in size and shape, they are caused by the expansion and contraction of ground water after water has entered the ground under the pavement. When water freezes, it expands. Think of when you make ice cubes — a tray full of water is put into the freezer, and when you remove the tray from the freezer, the water has expanded.
This same effect happens when water gets into the ground under the pavement. If it has a chance to freeze, it will take up more space under the pavement and the pavement will expand, bend, and crack, which weakens the material pavement. When the ice melts the pavement contracts and leaves gaps or voids in the surface under the pavement, where water can get in and be trapped. If the water freezes and thaws over and over, the pavement will weaken and continue cracking. As the weight of cars and trucks pass over the weak spot in the road, pieces of the roadway material weaken, which cause the material to be displaced or broken down from the weight, creating the pothole.
What happens when salt is brought into the picture? Water freezes at 32 degrees Fahrenheit. When salt is used, it lowers the temperature at which water will freeze. This creates an artificial freeze-thaw cycle that permits more occurrences of the damaging cycle to occur. This happens more often in the spring because of the melting that takes place and because the temperatures fluctuating above and below the freezing point very frequently.

Even the most well-designed asphalt pavement system can’t escape the damaging effects of Mother Nature. How can facility owners or building managers know which preventative maintenance strategies are best for them?
In relatively new pavement showing the beginning signs of deficiencies such as surface cracking, preventative maintenance can add years to the life of an asphalt pavement system. Planning a pavement maintenance program early on can save both time and money.
Here are some helpful processes for maintaining your commercial asphalt system:
Crackfilling – Crackfilling typically refers to the process of blowing out and cleaning cracks prior to installation of a crackfiller material. This is also known as the “blow-and-go” method. If properly done, crackfilling reduces the infiltration of water into the crack, which protects the pavement system from being weakened by moisture. Crackfilling should be used for wider-type, non-working cracks.
Cracksealing – The cracksealing process involves an additional step that’s highly recommended for longer-term performance, and involves routing of the crack. Cracksealing includes grinding out the crack to a wider, 0.5-inch by 0.5-inch to 0.75-inch by 0.75-inch square, providing a reservoir for the rubberized crackseal material.
Surface Treatments – There are many surface-treatment options to choose from. General categories of surface treatments include: coatings (asphalt or coal tar emulsions), penetrating or rejuvenating sealers or aggreagate-based seals such as slurry seals, chip seals and micro-surfacing.
Be sure to call Leritz / Busy Bee to inquire if any of these practices will work for your commercial pavement system!

Did you know that there is a world famous Asphalt Museum? Well neither did we – but there is!
The Asphalt Museums is actually more of a display located in the California State University – Sacramento office of Professor Scott Gordon. Gordon is a self-professed collector of asphalt and began the “museum” in the early 1990s.
The collection houses samples of asphalt form all over the world including one from the longest stretch of Route 66 in Arizona as well as samples from as far away as Tanzania, Italy and Scotland. After the museum became an internet phenomenon – it was listed for some time as a Wine Country attraction on Yahoo, people began sending in the samples from all over the world.
Gordon jokes that the museum is more of an internet joke than an actual museum but he counters that there are asphalt enthusiasts out there. The website not only details the collection but highlights art exhibits featuring asphalt as well. While it may not be an actual museum, we think it’s pretty neat.
