Like all other types of construction materials, asphalt pavements have a “shelf life.” That is, due to natural wear and tear, even the newest-laid asphalt will eventually need replacement. However, PLS sealcoating techniques will extend the life of your asphalt and protect it from chemicals, salts, and harsh weather which break it down. Here are some of the ways proper sealcoating can better maintain your asphalt surface in Tampa, Fl.
Life-Cycle Cost Analysis
Life-Cycle Cost Analysis, often called LCCA, is a method of evaluating the worth of a pavement segment. It takes into account both initial cost and maintenance costs in the future. Pavement rehabilitation, resurfacing, and reconstruction is considered over a specific period of time. LCCA is only one factor to consider. If after the analysis, the cost of replacement is only marginally more expensive than rehabilitation or resurfacing, then you might want to choose replacement. LCCA will direct you to the smartest buying decision.
Asphalt Pavement Life Expectancy
In the paving industry, the expected life of typical asphalt pavement is between 7 and 8 years without maintenance. However, PLS professional sealcoating can extend asphalt life expectancy up to double, 10 to 15 years on average. Here are some factors that determine life expectancy:
- The design of the pavement. Examples include asphalt compaction, asphalt mix, base, sub-base, depth of the asphalt, and draining.
- Traffic bearing capacity.
- Expected maintenance such as patching and sealcoating
- Surface’s exposure to harsh elements like oil, gasoline, grease, dirt and road salt.
When we say lifespan, we mean the period of time in which the asphalt service retains its strength and is able to endure the traffic load it was built to handle. The typical life of asphalt is about 7 to 8 years. After that amount of time has elapsed, the surface may need to be repaved.
Frequency of Treatment
Now, if you want to extend the life of your asphalt in Tampa Bay, we recommend sealcoating services and other minor repairs about every three years. You should allow three months to cure and eliminate all of the pavement’s surface oils. If you do not keep up a routine of maintenance, including sealcoating, you will find that the cost of repairs can be very high. While you may have to dip into your pockets for maintenance every few years, you will find that well worth to put off total replacement as long as possible.
