Bad Weather Still Abounds: Plan Paving Carefully


Despite several advancements in the world of hot- and cold-weather paving, there are still restrictions on when you can create a new patch of asphalt. Rain/snow and freezing weather remain the top enemies of asphalt paving, with excessive heat not far behind. This leads to scheduling issues as paving companies try to dodge bad weather and its secondary effects like wet ground. For homeowners who need a driveway repaved, however, the weather may not seem like such a big deal. If you're one of those homeowners and are ready to take matters into your own hands, take a look at why the weather is important for paving.

Oil Separation

Trying to pave anything in the rain is not going to work, and it's easy to see why; the rain mixes with whatever you're using as paving material and prevents the mixture from blending properly. In the case of asphalt, rain can make oils in the asphalt rise to the surface.

But rain isn't the only problem. Wet ground also makes oils separate in asphalt. Paving companies know they have to wait until the ground is dry because moisture will not allow the asphalt to set correctly.

Water Intrusion and Cracking

Another problem with moisture and asphalt paving is that the water can intrude into the mix, freeze, expand, and then cause cracking. This is essentially how potholes form in existing asphalt, and it's also a problem for new asphalt, only more so. In existing asphalt, some water seeps through a breach in the sealant. In other words, it's a localized phenomenon that affects only that section of the asphalt. For fresh asphalt that hasn't dried, there is no sealant to protect any of the expanse. The moisture can intrude in multiple spots, if not all over. The entire expanse of asphalt can become unstable and crumbly in a worst-case scenario.

Warping and Softening

Heat isn't that much better. You can pave on hot days as long as the ground is dry, but excessive heat is a problem. It prevents the asphalt from drying correctly. The heat can lead to warping and softening. Obviously, paving companies can work during the summer, but they start very early in the day. That gives the asphalt a chance to dry before the real heat of the afternoon sets in.

So if you're trying to get your driveway repaved and have not had luck getting a company to complete the job due to weather concerns, don't get annoyed -- be thankful. These companies are trying to prevent your new driveway from failing. If you need to patch spots, there are cold tars you can use in bad weather. Otherwise, work with a paving company, like Premier Paving & Sealcoat LLC, to set up a time during better weather to get the paving job done.

Make Your Walkway Wonderful

I own a small office building, and recently, I was looking for ways to improve the building's exterior. I felt that the whole office was very plain and lacked curb appeal. I want clients and business contacts to be impressed by the building and the grounds before they even step through the door. I knew that one thing I definitely needed to do was replace the crumbling walkway. I called a concrete contractor about fixing the walkway, and was impressed when he told me that I could actually make it look like a brick pathway, using stamped concrete. I decided to go for it, and it made a big difference in the appearance of the outside of the office. I think that more people should be aware of how they can use stamped concrete to improve their business's curb appeal.
