Parking Lot Paving Richmond – Things to Keep In Mind
A parking lot, without a doubt, takes a beating day in and day out. And, in many climates, temperature swings alone are sufficient to accelerate deterioration. Constant freeze/thaw cycles result in constant expansion and contraction (cracks), increasing the risk of water infiltration. The water then freezes, expanding the cracks even more and exacerbating the problem. Finley Asphalt & Concrete-Parking Lot Paving Richmond offers excellent info on this.
The harsh impact of daily traffic adds to the parking lot’s tension, not to mention the fact that it has its fair share of minor (and large) fuel and chemical spills and leaks from vehicles, machinery, and other sources. Also our warm and welcoming sun contributes to the detrimental consequences by relentlessly scattering the ultraviolet rays, speeding up the process of oxidation and allowing the asphalt to turn dry and brittle. What’s the end result? Obviously, there’s a higher chance of cracks and water penetration.
Many of these aspects add up to an uphill struggle when it comes to effectively maintaining parking lots. You must still be a step ahead of the eight ball
KEY IS TO KEEP IT ON THE SURFACE.
One approach to do this is to keep the worsening results on the parking lot soil. After all, the surface was made to withstand a pounding and, by serving as a barrier, prevent deterioration from affecting the base material. Sealcoating is an essential part of every parking lot management policy to guarantee that the pavement, or “cover,” manages to fulfil the demands for several years to come. Sealcoating, of course, does just as its name implies: it seals the top layer of asphalt concrete, enhancing its “shielding strength.”
While each project can differ based on the area, situation, venue, and other factors, the basic procedure is detailed below.
The Process of Pre-application
EVALUATE THE QUALITY OF THE ASPHALT
Assessing the consistency of your asphalt is crucial since it determines which planning measures to be completed prior to applying sealcoating. There are three key factors to consider when making that decision:
- I) Well Drained and Stable
- II) Frequency and Size of Cracks
III) Oil Free Surface
The degree of those three variables will significantly increase or decrease the efficiency of the sealcoating application and output.
For fresh asphalt sealcoating, it is normally only a question of the surface having had enough time to cure and surface oils to melt. The Asphalt Sealcoat Manufacturers Association (ASMA) suggests a 6 – 12 month cure period. An simple way to see whether the oils are gone is to broadcast a gallon of water on the surface and watch it roll. The fact that the water is moving in a uniform sheet indicates that the oils have dissipated. If the sheeting action has ‘rings’ or ‘breaks,’ it’s likely that it hasn’t been properly cured, or that there is an isolated trouble spot that will require a spot primer.
