The pavement in your driveway, on your street, or in front of your business is wet. You might think it rained a little earlier, and the water is still seeping through the ground. Something strange is going on with the pavement – is it wet because the water is oozing from below? If you’re unsure, don’t worry, you’re not alone. The liquid on the pavement is most likely bitumen pumping seeping up from underground. While the wet spots may seem minor, they can cause some real problems for pavement owners.
What is Bitumen Pumping?
Bitumen Pumping – or asphalt pumping – describes the action of asphalt binder rising to the surface through pavement cracks. It occurs when the asphalt binder, the sticky substance that holds asphalt together, starts to seep or ooze through cracks in the pavement. The asphalt binder can be either petroleum-based or asphalt cement.
Why does Bitumen Pumping Occur?
There are a few reasons why bitumen pumping may occur. Improperly compacting the asphalt mixer during initial installation is a very common cause. If there are voids or gaps in the asphalt, water will start to seep in and break down the asphalt binders, causing them to become soft and gummy.
Another reason for bitumen pumping is asphalt oxidation. Asphalt oxidizes when it is exposed to oxygen and sunlight, which causes it to become stiff and brittle. This can cause cracks to form in the asphalt, allowing water to seep in and start to break down the asphalt binders.
How Can I Prevent Bitumen Pumping?
The best way to prevent asphalt oxidation is to seal coat your pavement every two to three years. A seal coat creates a barrier between the asphalt and external elements, which helps prevent asphalt oxidation.
If you have cracks in your asphalt pavement, it is essential to repair them as soon as possible. By repairing cracks, you can help prevent water from seeping in and causing damage to the foundation.
What Are the Dangers of Bitumen Pumping?
Neglecting bitumen pumping is a recipe for disaster. If left unchecked, asphalt oxidation will lead to cracks, potholes, and, eventually, pavement failure.
Not only are the resulting asphalt repairs expensive, but the damage can also be dangerous. Cracks in asphalt pavement can cause trip and fall accidents. If you have bitumen pumping on your property, it is essential to take action to prevent further damage and keep your property safe.
How Do I Repair Bitumen Pumping?
The two main ways to repair bitumen pumping are asphalt resurfacing and asphalt patching. Asphalt resurfacing involves installing a new layer over the existing asphalt surface. This new layer will seal any cracks and prevent water from seeping in and causing damage. Asphalt patching is a more localized repair in which asphalt fills in individual cracks or potholes.
