Road drainage is much more important than you think. During heavy rainfall seasons, good drainage is especially important in order to avoid damage to the surface of the asphalt.
Besides being one of the most damaging elements to asphalt paving, standing and collected water is dangerous for drivers, pedestrians and cyclists. In order for the water to travel accordingly via flow lines, paved surfaces usually have a 1 percent slope. It is just enough for the water to drain down to curbs, wells and retention areas to avoid flooding on major streets and roadways.
Water is just one of the many elements that can cause damage to paved surfaces. The damage can be slow but also progressively quick. Along with water, sunlight, petroleum products and and other chemicals the paving comes into contact with, break the asphalt glue apart and weaken its strength. When those chemical bonds are no longer perfectly intact, the tiny cracks within the surface allow water, dirt, debris and chemicals to enter which furthers the deterioration. Eventually, alligator cracks, potholes and crumbly asphalt will form and need quick repair.
Determining Poor Road Drainage
During rainfall, spots where standing water has pooled will easily show you which areas have weak drainage. When weather conditions are dry, spotting areas that don’t drain properly can be difficult. For example, evaluating spots that collect dirt and debris can help in determining areas needing improved drainage.
So, how can you fix these issues and prevent them from shortening the life span of your property’s surfaces? Patching! Patching is a great way to restore proper and effective road drainage, eliminate alligator cracking on depressed surfaces and refresh old paving. Not only is it cost effective, but it is time effective as well – saving you costs associated with a lengthy asphalt removal and replacement service.
