Asphalt tapes are used to cover and seal joints and cracks in asphalt pavement. The main component of these tapes is asphalt itself, but there are different types of asphalt available with varying compositions. There are three common compositions: modified bitumen, butyl rubber, and acrylic adhesive. Modified bitumen is commonly used in hot climates since it has a high melting point, but butyl rubber is known for its flexibility and long-lasting properties. Acrylic adhesive, on the other hand, is used in cold temperatures due to its ability to remain pliable in extremely low temperatures.
Performance and Durability
The performance and durability of asphalt tapes are highly dependent on the materials used and the environmental conditions they are exposed to. The adhesion and cohesive strength of the tape is what determines its overall effectiveness. A higher adhesion strength means the tape can resist shear and peel forces, while a higher cohesive strength means it can resist splitting and tearing. The durability of the tapes depends on the nature of the environment as well as the volume and type of traffic that it regularly undergoes.
However, when it comes to performance and durability, modified bitumen asphalt tapes are the clear frontrunner. They are highly flexible and can conform to any joint or crack, which helps prevent water infiltration. This type of asphalt tape also has high-temperature stability thanks to its high melting point, which prevents it from melting and losing adhesion in hot climates. On the other hand, butyl rubber tapes have a highly flexible composition and offer superior waterproofing properties that can withstand heavy rain activity, while acrylic adhesive tapes possess more weather resistance for colder climates.
Another distinguishing factor in asphalt tapes is how they are installed. There are three main methods of installation: torch-applied, peel-and-stick, and heat gun-applied. Torch-applied asphalt tapes are the most demanding method and require a high level of skill and proper safety measures. This method involves using an open flame torch to heat the tape and apply it to the surface. Peel-and-stick tapes are the easiest and the most popular method of installation, as they can be easily applied in just one step. Lastly, heat gun-applied tapes require a heat gun to apply the tape, which offers a faster and more secure option for installation in larger areas.
Cost and Maintenance
It’s no secret that asphalt tapes come in at different price points. The cost of installation is typically influenced by various factors, including ease of installation, quality, durability, and even the brand. Modified bitumen asphalt tapes have a slightly higher cost when compared to butyl rubber and acrylic adhesive tapes due to their superior properties, but it’s important to note that they are a considerably cost-effective investment. In terms of maintenance, these tapes don’t require much upkeep nor can they be easily removed once installed, making them a long-term asset in the paving industry.
While there are various types of asphalt tapes available in the market, each with their unique composition and properties, the ideal choice for a successful installation ultimately depends on your particular application. Modified bitumen asphalt tapes offer the best in terms of performance and are ideal for hot climates, while butyl rubber has superior waterproof properties, especially in heavy rain areas. Acrylic adhesive tapes work best for cold temperatures.
