Longitudinal joint sealant market seen reaching $2.15 billion by 2030

The global longitudinal joint sealant market is projected to grow from $1.43 billion in 2025 to $2.15 billion by 2030, driven by road expansion, urbanization and infrastructure maintenance. North America led the market in 2025, while Asia-Pacific is expected to grow fastest through the forecast period.

Why it matters: - Longitudinal joint sealants help extend pavement life by blocking water, dirt and other contaminants from entering road joints. - Demand is rising as governments and builders focus on more durable roads, lower lifecycle costs and climate-resilient infrastructure. - The market is tied to spending on highways, airports, bridges and urban transport corridors.

What happened: - The Business Research Company projected the global longitudinal joint sealant market will grow from $1.43 billion in 2025 to $1.55 billion in 2026. - The report expects the market to reach $2.15 billion by 2030. - The forecast implies an 8.3% compound annual growth rate from 2025 to 2026 and an 8.5% CAGR through 2030. - The report was published July 18, 2026 as part of The Business Research Company’s Longitudinal Joint Sealant Global Market Report 2026.

The details: - Longitudinal joint sealants fill and seal joints that run parallel to pavements or structural elements. - The materials are designed to resist water intrusion, dirt buildup and damage from temperature-driven movement and mechanical stress. - Market growth is being driven by road construction, public infrastructure investment, pavement repair and maintenance, expressway projects and airport construction. - The report also points to demand from polymer-modified sealants, cold-applied sealants and other climate-resilient materials. - The report highlights a shift toward environmentally sustainable and low-emission construction chemicals. - A free sample report is available here.

Between the lines: - Road maintenance spending is a clear signal for sealant demand, since sealing joints can reduce cracking and slow pavement deterioration. - In April 2025, the UK Parliament reported local authorities spent $6.0 billion on road maintenance in 2023/24, including $3.75 billion for structural treatments and $1.63 billion for routine maintenance. - Urbanization is expanding the addressable market because denser cities need stronger roads to handle heavier traffic volumes. - Our World In Data projected in December 2024 that the global population will reach about 9.8 billion by 2050, with nearly 7 billion people living in urban areas. - Heavy-duty vehicle growth is adding more wear to roads, increasing the need for durable joints and better pavement protection. - Truck & Bus Builder Publishing Ltd. reported in March 2024 that new commercial truck registrations in Britain rose from 40,716 in 2022 to 46,227 in 2023. - North America held the largest market share in 2025 because of advanced infrastructure and ongoing maintenance activity. - Asia-Pacific is expected to post the fastest growth during the forecast period, supported by urbanization, infrastructure investment and expanding transportation networks.

What's next: - The report expects continued demand from highway, airport and bridge projects. - Aging road networks in developed countries are likely to support replacements and repairs. - Smart city and transport corridor programs should add more demand for sealing materials. - The report also includes new 2026 features such as market attractiveness scoring, TAM analysis, company scoring matrices, Excel forecasting dashboards and hotspot infographics.

The bottom line: - The market is moving from maintenance-driven demand to a broader infrastructure upgrade cycle, with durability and sustainability shaping the next phase of growth.
