When we think of asphalt, we don’t imagine it to be rough and bumpy. Asphalt is known for its smooth finish and durability, which is why the bumps on their asphalt pavement come as a surprise to many homeowners. After spending a significant proportion of their savings on asphalt pavement, homeowners are left disappointed when they see bumps and cracks emerging soon after installation.
An experienced paving contractor like Resource Pavement Group in St. Petersburg will consistently deliver a smooth asphalt surface free of any defects.
Although repairs might eliminate the cracks, the question still remains as to why your asphalt pavement is not smooth enough?
This blog post will clear the air regarding rough asphalt surfaces and list various factors that cause them to turn out uneven.
1) Using the Wrong Aggregate Mix
If you’ve heard people insist that the quality of the aggregate mix is crucial for forming a smooth asphalt pavement, they weren’t exaggerating. The problem lies in the fact that not all aggregates are created equal. Using the wrong aggregate mix means that the surface of your asphalt will wear out faster, and this is a surefire way to make it uneven.
The best aggregate mix for an asphalt pavement should contain sandstone or crushed stone that’s smooth in texture and size. If necessary, the larger stones can be used as fillers, but they have to be inert to disintegrate under pressure with time. In any case, you need to steer clear of using contaminated aggregates because these are no good for forming a stable base for paving purposes.
Another crucial aspect worth considering before selecting an aggregate mix is its load-bearing capacity. Some mixes do not fare well under heavy traffic loads over long periods.
2) Not Compact Enough
One of the possible reasons why your asphalt surface is not smooth is that it wasn’t compact enough. When paving a new parking lot, you need to ensure that the layer of aggregate material on top of the base is well-compacted so that it can form an even and level surface for cars to drive over it. Compacting an asphalt pavement is challenging because the aggregate is usually less dense than concrete or cement. As a result, you’re left with a bumpy texture on your pavement due to uneven protruding stones sticking out just below its surface.
3) The Contractor Miscalculated the Aggregate Requirement for the Pavement
A contractor can also be guilty of miscalculating the aggregate requirements of an asphalt surface. Contractors need to consider several factors when determining the aggregate quantity and quality. This includes the slope and existing soil structure. Miscalculations can result in insufficient surface material as rough patches will emerge in areas that use less asphalt.
