Asphalt rubber joint sealant formula, also known as rubberized asphalt or rubberized joint sealant, is a specialized type of sealant used for filling and sealing joints in asphalt pavements and concrete structures. It is designed to provide a flexible, durable, and watertight seal that can withstand the stresses and movements typically encountered in these applications.

Asphalt joint sealing formula key features

  1. Composition: Asphalt rubber joint sealant is typically made by blending asphalt cement, which is a petroleum-based binder, with crumb rubber obtained from recycled tires. The crumb rubber is finely ground to a specific size and then mixed with the asphalt cement to form a rubberized binder.
  2. Benefits: The addition of crumb rubber to the asphalt cement enhances the properties of the sealant. It improves flexibility, elasticity, and resistance to cracking, making it ideal for sealing joints that experience movement and stress. The rubberized properties also provide better adhesion to the substrate and improved resistance to water infiltration.
  3. Application: Asphalt rubber joint sealant is applied to the prepared joint or crack using various methods, such as pouring, troweling, or using specialized equipment like hot-applied melters. The sealant fills the joint or crack, forming a continuous and flexible seal when it cools and solidifies.
  4. Compatibility: Asphalt rubber joint sealant is compatible with asphalt pavements, concrete structures, and other common construction materials. It can be used to seal joints in roadways, highways, airport runways, parking lots, bridge decks, and other similar applications.
  5. Durability: Rubberized asphalt joint sealants are known for their durability and long-lasting performance. They can withstand a wide range of temperatures, weather conditions, and traffic loads without deteriorating or losing their sealing properties.
  6. Maintenance: Over time, asphalt rubber joint sealants may experience wear and degradation due to exposure to UV radiation, chemicals, and traffic. Regular inspection and maintenance are important to ensure the sealant remains intact and effective. Damaged or worn-out sealant should be replaced to maintain the integrity of the joint or crack seal.

Safety Considerations

During the application of asphalt rubber joint sealant, it is important to follow safety guidelines, including wearing appropriate personal protective equipment (PPE) and working in well-ventilated areas. The heating process used for melting the sealant may generate fumes, so proper precautions should be taken.

This asphalt rubber joint sealant formula is mention clearly when a  space between concrete slabs is filled using polypropylene tow saturated with cationic asphalt emulsion. The tow can be saturated before or after it is inserted into the joint or crack. Several layers of tow can be used to fill up to about A-inch below the floor surface and cationic asphalt emulsion can be added to bring the packed joint level to about an inch above the floor surface.

A polymer-modified asphalt composition consists of asphalt, an oil, a polymer additive and an ionomer. The compound can be used in sealants to seal cracks or joints in concrete or asphalt structures. The sealant is applied to the crack or joint in an amount sufficient to fill the crack or joint and the sealant is cured to bond the crack or joint. The mixture can be prepared by heating a mixture of asphalt, oil, a polymer additive, an aggregate and an ionomer, and mixing the mixture until the ingredients are evenly mixed.
