An asphalt pavement goes through extensive wear and tear during its lifetime. Many harmful exogenous elements contribute to a pavement’s deterioration; regular maintenance and repair are the only way to counter them.
Measures like asphalt sealcoating and resurfacing can help prevent premature pavement failure while restoring the pavement’s original look. Although both measures help prolong a pavement’s lifespan, an asphalt surface requires them at different stages of its life cycle. Consulting an experienced paving contractor can help you understand the difference between asphalt sealcoating and asphalt resurfacing so you can select the best option. Sweeney’s Pavement Maintenance is a professional contractor serving clients in Garden City and other locations across Kansas.
In this blog post, we’ll demystify these two popular asphalt repair and maintenance measures and explain why they are crucial to an asphalt pavement’s survival.
What is Asphalt Sealcoating?
Asphalt sealcoating involves applying a sealant in order to seal cracks on the asphalt surface. The protective coating on the pavement prevents water from seeping through the cracks. Sealcoating typically lasts for two to three years before another application is required.
The bituminous-based or acrylic liquid emulsion used in asphalt sealcoating provides an extra protective layer to the surface and blocks deteriorating elements from damaging the asphalt surface. The deteriorating factors include oils, salt, automotive fluids, water, and harmful UV rays. Sealcoating provides a smooth coating over the entire surface. Additionally, it is also relatively cheaper as compared with the repair options.
What is Asphalt Resurfacing?
Resurfacing is essentially applying a new asphalt layer on top of the old pavement. This process should be carried out if the pavement meets some or all of the following conditions:
- The pavement foundation is structurally viable
- The pavement is not more than 20 years old
- The cracks are smaller than a quarter-inch wide and are less than two inches deep.
- At least 70% of the pavement is in good shape.
The Differences Between Asphalt Sealcoating and Resurfacing
Asphalt sealcoating and resurfacing have many differences.
First: Asphalt sealcoating is a maintenance measure, whereas asphalt resurfacing is a full-fledged repair activity.
Second: Sealcoating is accomplished by applying an emulsion coating over the existing surface, whereas asphalt resurfacing requires removing the damaged areas and replacing them with new paving material.
Third: The cost of asphalt sealcoating is considerably lower than the cost of asphalt resurfacing.
Fourth: The pavement is treated differently in these two procedures – sealcoated surfaces have grooves to allow water to drain, while pavements that have undergone asphalt resurfacing do not have any such grooves.
