Crack sealer combines bitumen, SBS polymer, asphaltum, rubber process oil, and crumb rubber under controlled heat and pressure. This high-quality mix effectively seals cracks and joints in asphalt pavements, parking areas, and cement surfaces. By using polymer-modified bitumen with natural asphaltum, it offers excellent flexibility, adhesion, and resistance to deformation under traffic loads and temperature variations.
Asphalt Sealer for Pavement Protection
Asphaltum-based sealers effectively seal expansion joints, long and cross cracks, and construction joints between concrete and asphalt shoulders. Because they are eco-friendly, many countries now use asphaltum crack sealers to maintain roads and extend pavement life.
Roof Seal Additive Applications
In construction and maintenance, asphaltum crack sealer is also used as a roof seal additive or adhesive. It efficiently fills cracks in asphalt or concrete surfaces — such as parking decks, driveways, and roofs — after cleaning with air or water. The modified bitumen rubber asphalt acts as a bonding agent, providing strong adhesion for roofing materials and waterproof protection against leaks and weathering.
Asphaltum for Road Pavement Sealing
Instead of replacing entire pavement sections, asphaltum offers a cost-effective and sustainable repair method. Cracks in asphalt surfaces can be effectively sealed using asphaltum-based crack sealers, preventing moisture penetration, surface degradation, and costly reconstruction. This process not only restores the appearance of the pavement but also strengthens it against thermal expansion and vehicular stress.
Crack Repair Additives and Challenges
Traditional asphalt sealers have shown certain limitations — such as melting at high temperatures, softening under vehicle pressure, and reduced durability. These issues often lead to the sealer moving away from the crack or becoming slippery, requiring repeated maintenance. The innovative asphaltum-based crack repair system addresses these weaknesses with superior thermal stability and elasticity.
Asphalt Sealcoat Performance
Conventional sealers may lose their filling capability when exposed to high heat. In contrast, asphaltum sealcoat retains its shape and adhesion, maintaining an effective seal even under hot conditions and traffic stress. This stability makes asphaltum sealers ideal for high-temperature regions and heavy-duty pavements, where ordinary products fail.
Grout and Surface Sealer Combination
In deep cracks, a grout or mortar base may be used before applying the asphalt sealer. This two-layer system ensures full crack filling and a smooth, level finish. However, traditional grout fillers can shrink over time, causing the sealer to drop into the crack. Asphaltum-modified sealers reduce this problem with enhanced bonding strength and minimal shrinkage, ensuring a durable, flush surface repair.
Advantages of Asphaltum Crack Sealer
The use of asphaltum in crack sealing provides several key benefits:
Superior Adhesion: Strong bonding to both asphalt and concrete surfaces.
High Softening Point: Maintains stability under hot climates.
Elastic Recovery: Flexibility prevents re-cracking due to thermal movement.
Long Service Life: Reduces maintenance frequency and repair costs.
Eco-Friendly Composition: Asphaltum is a naturally occurring bitumen, making it a sustainable alternative.
While some products attempt to improve performance by adding aggregates like sand or limestone, these fillers often detach over time. Asphaltum sealers, on the other hand, deliver natural cohesiveness without additives, ensuring long-term durability and weather resistance.
Improved Crack Repair System by asphaltum
The asphaltum crack seal system provides a breakthrough in pavement maintenance. It overcomes the shortcomings of older technologies by combining high-grade bitumen and natural asphaltum with SBS polymer modification. This formulation ensures strong flexibility, excellent adhesion, and high temperature resistance, ideal for use in:
Highways and airport runways
Parking lots and driveways
Concrete joints and expansion cracks
Roof sealing and waterproofing systems
In short
Asphaltum-based crack sealers represent a modern, efficient, and eco-friendly solution for road maintenance, roofing, and construction applications. They not only seal and protect pavement cracks but also enhance the structural integrity and longevity of surfaces under extreme conditions.
