24-Year Expert: Tongda Highway’s Road Maintenance Solutions & High-Quality Road Sealant for Global Clients

For road contractors and municipal engineering teams across Europe, the Middle East, and Southeast Asia, finding reliable road maintenance solutions is a constant priority. As infrastructure projects expand and existing roads age, the need for durable, cost-effective materials and equipment only grows—and that’s where Tongda Highway comes in. Founded in 2001, Xinxiang Tongda Highway New Technology Co., Ltd. (www.tdasphalt.com) has spent 24 years refining our road maintenance products, becoming a trusted partner for businesses worldwide looking to fix pavement cracks, potholes, and aging issues efficiently.

At Tongda Highway, our focus is on delivering products that solve real-world problems for our B2B clients. Our core lineup includes road sealant, crack filler, joint tape, cold patch asphalt, and pavement repair machines—covering every stage of the road maintenance process. Unlike generic manufacturers, we prioritize “technology-driven quality”: we hold over 80 national patents, are ISO certified, and every product we make meets international standards like JT/T 740-2024. Our most popular product, road sealant, is available in 5 temperature grades (ranging from -40℃ to 0℃), making it perfect for any climate. Whether you’re working in the 45℃+ heat of the Middle East, the freezing winters of Northern Europe, or the humid tropics of Southeast Asia, our sealant maintains strong elasticity, adhesion, and waterproofing—keeping water out and extending pavement life by 5 to 8 years.

What truly sets us apart as a B2B road maintenance manufacturer isn’t just our high-quality products—it’s our one-stop customized solutions. We understand that every region has unique road conditions and needs: highways require large-scale, efficient road repair equipment; municipal roads need quick, low-disruption construction; and rural roads call for affordable, easy-to-use options. That’s why we’ve designed complete matching solutions: self-propelled crack filling machines paired with hot-applied road sealant to cut labor costs and speed up projects; self-adhesive joint tape that’s ready to use without heating for small cracks; and all-weather cold patch asphalt that works in rain or snow, letting you fix potholes fast and reopen roads immediately.

Our “global brand, localized service” approach has helped us export to over 50 countries, with our products used in highway maintenance, municipal construction, airport runways, and parking lots. One of our recent success stories?

A 50km highway crack repair project in the Middle East, completed in just 15 days using our high-temperature road sealant and crack filling machines—earning rave reviews from the local engineering team. This project is just one example of how we deliver on our promise of reliability and efficiency.
