Foam Bitumen: What Are the Appropriate Uses?
There is a constant need to keep roads and paved surfaces in good shape. It makes movement fast, safe and easy. When good roads extend into residential areas, they not only facilitate fast movement but also maximise the value of your property. Sadly, certain materials no longer meet the requirements of a sustainable road or paved surface. Cracking problems can occur when mixtures that are dominated by stuff like fly ash, lime and cement are used for driveways. Replacing the materials with foam bitumen is your best bet. Foam bitumen contains water, bitumen and air. Introducing jets of cold water into the hot bitumen causes it to expand significantly, and you can stabilise it to make roads. The following piece outlines the most appropriate ways of using foam bitumen.
Addressing Extreme Flushing Problems
Have you ever heard of bleeding roads? If not, then this is your chance to learn. A bleeding or flushing road occurs when a shiny, dark film of asphalt covers the surface of the road. It happens because the asphalt in the layers of the road moves upwards and creates an undesirable surface that jeopardises the safety of road users.
Flushing is a huge problem because you cannot correct it using conventional resealing methods. You can avert this problem by using foam bitumen. When laying the pavement, you incorporate bitumen mist, which binds the materials firmly and keeps them from popping towards the top surface.
Delivering Excellent Shear Strength
When you think about a driveway, you need to consider the high levels of stress that vehicles will impose on that surface. Loaded vehicles will tear your pavement apart unless you equip it with materials that can withstand all the stress. Foam bitumen has excellent granular compaction achieved through in situ stabilisation. Foam bitumen roads are the best when building roads where you cannot control the tonnage carried by the vehicles driving over it.
Handling Repeated Patches
Potholes are a nuisance for many driveways. They result from structural damage of the material used to make the driveway. Lots of water seeping into the driveway's structure is another recipe for pothole problems. When they occur, most people patch the surface to keep the road in good condition. However, the damage can be severe to an extent where patching does not work. You need to replace ordinary concrete mixtures with foam bitumen when patching your roads. Foam bitumen forms a material that binds well to preexisting materials on the surface.
