` Finally, create an overview site map. Google Earth is a helpful tool that shows the exact square footage of the entire parking lot. A site map is necessary to ensure accurate area measurements for seal coating.
Identifying Needed Materials
Next, identify the materials to be used. Clarity is paramount so contractors don’t use substandard products that will not last. This requires understanding the materials used and why those materials are necessary for a successful asphalt installation. ` High Strength Concrete Curbs and concrete should be poured with high strength concrete. This concrete should be 4000 PSI mixed with a 6-sack mix. This gives you a very strong concrete that is less likely to crack and fail.
` Marking Paint Painting and striping should be with a DOT-approved marking paint. These are high quality products that do not chip or fade prematurely. Also, these products dry quickly so patrons likely won’t smear it or track it. This is why it is important to identify the exact paints in any request for proposal.
` Seal Coating When it comes to seal coating, we recommend two coats of Armor Seal A 100 HD, or similar. This is a heavy-duty commercial grade product. There should be two coats installed and that should be stated upfront. Otherwise, contractors may dilute the product with water or only apply one coat, which will significantly lessen how long the seal coat will last. With two coats, the application should last 5-7 years.
Coats of seal to be installed should be stated up front, otherwise contractors may dilute the seal solution or install insufficient coatings.
` Crack Filler We recommend direct fire crack filler from Armor Seal or similar. This is very important, and it is recommended that this be done annually. Crack filler prevents surface water from getting to the substrate soil. To see how this could be a problem, picture what happens when you put a soda
` Milling If the lot is in such bad condition then it must be completely replaced, we recommend a mill and pave option. Milling is where the asphalt contractor comes in with a milling machine and grinds and compacts the existing asphalt and hauls off the grindings. If, for

can in the freezer. It expands and ultimately explodes. Similarly, water gets under the asphalt through cracks and then as the ground temperature drops below freezing, the water under the asphalt freezes and expands creating more cracks, more damage, and more money in costly asphalt repairs. Sealing these cracks in the parking lot helps prevent this costly damage from occurring.
Water entering through cracks and freezing under asphalt can lead to damage for the same reasons a soda can expands and explodes in the freezer.
` Hot Mix Asphalt (HMA) All new paving or patching should be done with Hot Mix Asphalt (HMA). We currently consider HMA the best because it cools very quickly, which allows for quick vehicle access after the work has been completed. HMA is also the most durable grade of asphalt, and because of this, it’s used on most high traffic roads and freeways. We never want to allow any type of cold mix asphalt application. Cold mixes will flake out and fail.
