The snow has melted, the days are longer, and Memorial Day is around the corner. We are also well into our 2016 work season. While it would be our preference to work every day, sometimes Mother Nature does not cooperate. Weather in this area can vary between light sprinkles to heavy down pours. This raises the question of when can work in the rain?
Occasional light sprinkles should not be cause for us to shut down operations. However, a steady downpour, either light or heavy, will likely require us to reschedule. Here are some reasons why.
Heavy rain cools the asphalt, making proper compaction difficult and excess moisture can cause separation of the asphalt binder from the aggregate. A quality driveway or parking lot requires a firm, stable, well-draining crushed aggregate base. Heavy rain and moisture present while paving can sabotage that base down the road causing failure.
The Asphalt Institute sums it up best, asphalt pavements are designed to last for many years, so don’t let a sense of urgency to get the job done quickly allow you to make decisions which could strip years away from the pavement life.
