Asphalt is a popular choice as a paving material. It’s low cost, durability, and easy maintenance make it an excellent choice for residential or commercial pavement applications. An asphalt pavement installed by an experienced, professional asphalt contractor like National Pavement Partners (providing services in Denver, Colorado Springs, Fort Collins, Loveland, and Castle Rock, CO) lasts decades with regular maintenance.
If you are considering asphalt paving for your business or home, make sure to avoid these five most common mistakes.
1. Inadequate Preparation Time Before Installation
Asphalt paving is a technical process that requires extensive preparation. Before asphalt installation, you must clean the surface, sweep off any loose debris and remove large stones or roots to avoid damaging the new pavement. You should also apply asphalt binder prior to placing the new asphalt.
The preparation time for asphalt paving varies depending on the size of the project and whether or not you have any special requirements, such as installing pavers at intersections or in parking garages. When asphalt is not pre-formed in panels, it can take up to two days before installation can begin.
2. Using Low-Quality Material for Asphalt Paving
Using low-quality material for asphalt paving can result in several problems, including but not limited to:
- Cracking and spalling;
- Higher cost of maintenance because it requires more upkeep (e.g., more roto-milling) to keep the surface even; this is because low-quality asphalt is more porous, which means that it absorbs water and other liquids readily;
- Inability to withstand heavy traffic and high volume;
- Asphalt pavement with low-quality material is more likely to develop a rough surface & be less durable, which in turn will cause it to require higher maintenance;
3. Poor Compaction of Surface Material During the Installation Process
Poor compaction may result in the following issues:
- If the material is not adequately compressed during asphalt installation, it results in a compromised state that lacks the required strength and longevity;
- Poor compaction can cause voids in the asphalt leading to poor density.
- The asphalt may also have poor drainage, leading to faster accumulation of water and snow;
4. Inadequate Curing After Pavement Installation
Curing after the asphalt pavement installation helps in strengthening it and maintaining its quality for years to come.
- Inadequate curing may lead to asphalt shrinkage, rutting and cracking. This will bring about asphalt failure, which may lead to accidents;
- Asphalt pavement needs at least 24 hours of curing/cooling time before it can sustain vehicular traffic;
5. Improper Grading
When you are installing an asphalt parking lot, correctly grading the underlying subgrade is critical. During grading, any sloped areas are removed & reshaped to create even surfaces and then leveled out so water can safely flow off the site in all directions. Without a proper slope on your pavement, water will accumulate over time and destroy the integrity of the surface.
