Winter is that time of the year when roads are exposed to precipitation and damaging weather. And with snow, ice, and rain, your lot can become flooded and blocked by ice and water. Even worse, you might have to deal with huge piles of snow up to 3 to 5 inches high and huge downspouts that you can’t control no matter how hard you try to plow – which is why this season is considered as one of the main factors of asphalt damage.
But is it advisable to do parking lot repairs during the winter season? And what kind of asphalt repairs that can be done during this time of the year?
Get to know the answers as you continue reading this post.
According to experts, winter is not actually the ideal time to conduct crucial asphalt repairs. And the reason for this is excessive moisture seeps through the pavement and causes it to expand or contract as the temperature changes which leads to worsening of existing bumps or cracks. Even so, there are pavement repair methods that can be done during winter time to prevent cracks road breakdown.
Whether you are fixing surface cracks, sealing or filling potholes, or replacing certain sections of the asphalt, there are 2 ways for repairing asphalt pavements during winter time, and these are the hot mix technique and cold mix technique.
Hot Mix – In this process, the asphalt mixture must remain hot so it will be compact during application. If the mixture is not hot enough, the asphalt won’t set properly. Also, if the outside temperature is cold, the mixture will cool faster that it may no longer be effective the moment it is placed or poured into the affected area of the road.
Which is why the Hot Mix technique is only done when the external temperature remains consistent above 55°F for at least a week. Otherwise, the whole repair process won’t work.
Cold Mix – Unlike the Hot Mix method of repair, the Cold Mix technique doesn’t rely on temperature to be effective. That’s why it’s ideal for emergency fixes during the winter season. However, it’s not recommended for the replacement of parking lots, driveways, and large roads.
Some driveway repairs may require the removal of damaged asphalt areas through heating, but the weather is usually inclement during winter time. Good thing, the Infrared method makes use of a technology that makes sub-surface heating possible despite the prevailing cold conditions.
Since winter is the least suitable condition for doing road repairs, particularly on asphalt surfaces, here are some things to take note of when the process is inevitable:
