Many out there have often wondered what the advantages of asphalt are over concrete in Utah. The climate in Utah is one that can be very extreme depending on the time of the year. In the winter you can have weeks in a row where the temperatures dont reach freezing. In the summer there are weeks in a row where the high temperature of the day is in the triple digits. The temperatures can rise and fall very quickly with a storm coming in. All these factors will make your decision on whether to have asphalt or concrete more complicated.
A lot of the things you need to keep in mind when you are considering between the two is what type of surface you are going to replacing or installing for the first time. If you notice in Utah County and Salt Lake County the freeways are all made out of concrete. When you get down towards the bottom of Utah County and Santaquin, Utah the freeways go to two or three lanes and they are made out of asphalt. Also in residential areas you will see that asphalt and concrete can mix quite well. Here is a picture of just that combination. This was a residential house that had a long driveway in the mountains. The asphalt was much easier to use for most of the job but concrete is better to use once it gets closer to the home because it is more solid and connects nicely with the structures foundation.
