What Is a Bitumen Base?
A bitumen base is formed by compacting layers of aggregates, sand, mineral filler, and hot bitumen binder to create a strong, flexible, and long-lasting foundation for outdoor sports courts. It acts as a durable blacktop layer designed to support acrylic coatings, offering the stability and smoothness required for professional sports performance. In simple terms a bitumen base is a flexible, weather-resistant bitumen foundation engineered to deliver consistent playability and reduced surface cracks under acrylic sports flooring.
Unlike road bitumen, a sports court bitumen base requires:
Smoother finish
Sports courts require a finer, more polished bitumen finish to ensure the acrylic layers adhere evenly and the final surface feels uniform underfoot. This smoothness eliminates bumps or surface irregularities that can affect ball speed, bounce, and player safety.
Finer aggregates
Finer aggregates are used so the surface stays compact, tightly bound, and free from loose stones that could damage acrylic coatings or disrupt play. This results in a cleaner, denser surface specifically suitable for tennis, basketball, pickleball, and other precision-based sports.
Tighter tolerances
Sports courts demand precise leveling and thickness control, allowing the bitumen layer to remain perfectly even across the entire playing area. This accuracy ensures consistent performance, preventing dead spots, dips, or uneven bounce.
Precise slope (1%)
A strict 1% slope is required to drain rainwater quickly without affecting gameplay or causing waterlogging during monsoon conditions. This engineered slope helps maintain the lifespan of acrylic layers and prevents standing water from damaging the surface.
Better compaction
High-density compaction ensures the bitumen base remains stable, crack-resistant, and capable of withstanding continuous player movement. Proper compaction strengthens the surface and prevents future depressions, waviness, or structural failure.
This ensures the surface is ready for synthetic acrylic flooring on bitumen, which requires superior uniformity for ball bounce and performance.
Where Is Bitumen Base Used in Sports Court Construction?
Tennis Courts
Bitumen base is ideal for outdoor tennis courts because it offers a smooth, uniform, and flexible surface that supports consistent ball bounce. Its lower cracking rate makes it more durable under India’s heat and monsoon cycles.
Basketball Courts
Outdoor basketball courts often use bitumen because its flexibility absorbs surface stress, reducing cracks and undulations. The smooth bitumen finish also supports better traction and long-term performance.
Volleyball Courts
Volleyball courts in schools, societies, and clubs prefer bitumen base due to its excellent drainage and weather resistance. It ensures a safer, non-slip foundation for acrylic coatings in outdoor settings.

Step-by-Step Process: How a Bitumen Base Is Constructed
1. Earthwork & Marking
The site is cleared of vegetation, debris, loose soil, and obstacles to create a clean working surface. Accurate boundary marking ensures the court dimensions and layout are aligned with the final sports flooring plan.
2. Sub-Grade Preparation
The natural ground is compacted to 95% Proctor density to provide a stable base that prevents future settlement or unevenness. Proper grading ensures the ground is level and ready to support the upper structural layers.
3. Sub-Base Construction
A GSB/WMM layer is laid to provide load-bearing capacity and distribute weight evenly across the court foundation. This layer also helps in achieving uniform compaction and long-term structural strength for the sports court base.
4. Base Course Application
A 40–50mm bitumen base course is applied using a hot mix to form the first strong structural layer of the bitumen court base. This layer is compressed while hot using an 8–10 ton roller to reach maximum compaction and density.
5. Wearing Course Application
A fine bitumen wearing course (25–30mm) is applied to create a smooth, uniform, and crack-resistant surface layer. This layer must be perfectly leveled and seamless, as it directly impacts the performance of the acrylic sports flooring system.
6. Slope Correction
A precise 1% drainage slope is maintained across the surface to ensure efficient water runoff during rain. This prevents waterlogging, puddles, and long-term damage to acrylic coatings.
7. Cooling Time
The newly laid bitumen must cool and cure for 24–48 hours to stabilize before applying acrylic coatings. This ensures proper bonding of resurfacer, cushion layers, and color coats and prevents trapping of heat or moisture.
8. Acrylic Sports Flooring System
The system begins with primer and acrylic resurfacer to fill pores and create bonding with the bitumen surface. Cushion layers, color coats, and precise line marking are then applied to deliver a professional, durable, and high-performance sports court.
