How to Construct Polymer Cast Diamond Tactile Paving for Colored Asphalt Pavement

Product Advantages: Aesthetic, durable, short construction period, the entire road surface can be formed in one go (cast-in-place tactile paving can be directly laid on the finished road surface, avoiding the hassle of secondary paving typically caused by traditional tactile paving bricks), significantly reducing road construction costs and material waste. Various colors and styles are available, offering flexible combinations.







Product Description: Polymer cast-in-place diamond tactile paving is a continuous tactile paving system made from inorganic high-strength polymer materials combined with specialized molds, constructed on existing road surfaces through cast-in-place methods. It is divided into two types: guidance strips and guidance points. Standard widths include 300mm, 400mm, 500mm, and 600mm, with flexible customization available based on actual needs. It forms a permanent bond with asphalt concrete or cement concrete base layers, offering wear resistance, slip resistance, stain resistance, and synchronous expansion and contraction with asphalt pavement.

II. Construction Process and Operating Methods

Polymer cast-in-place diamond tactile paving is a new tactile paving technology that can be constructed on-site on traditional black asphalt concrete and gray cement concrete road surfaces.

2.1 Construction Process

Base layer inspection - Base layer cleaning and treatment - Layout marking - Tape application - Base leveling and mortar spreading - Mold placement - Filling with diamond tactile paving mortar - Leveling and finishing - Curing to specified time - Surface cleaning - Application of sealant for surface sealing - Drying and curing - Acceptance inspection - Opening to traffic - Final acceptance.

2.2 Construction Equipment and Tools

The construction process for diamond tactile paving is relatively simple, requiring only the following equipment and tools: one mixer, one disperser, several tactile paving molds, one material transport vehicle, rolling rollers, specialized serrated rubber screeds and flat rubber screeds, one powerful blower, one generator, brooms, and other general equipment and tools.

2.3 Construction Personnel

One team leader and 5-6 construction workers per group.

2.4 Construction Preparation

4.1 Review drawings and layout marking

Carefully review construction drawings and verify positions on-site one by one. If necessary, mark points and apply tape.

4.2 Material inspection

Polymer cast-in-place diamond tactile paving is an on-site constructed ground system involving multiple processes and materials. Before construction, ensure material consistency and compatibility. Emulsion materials should show no significant skinning, clumping, or abnormalities; powder materials should be free of clumps. 2.4.3 Trial mixing and sample preparation

Different base layers and environments can affect the curing time of polymer diamond tactile paving. Therefore, before formal construction, conduct on-site trials strictly following the mix ratio and methods set for batch operations. Proceed with batch operations only after ensuring no significant defects in curing.

2.4.4 Base layer conditions and treatment

The base layer should be solid and clean. Asphalt concrete surfaces should be free of bleeding, loose dust, delamination, or aggregate loss.





For cement concrete surfaces with strength below C25, treat the surface by milling, scabbling, grinding, sandblasting, or roughening (for newly poured concrete) to expose aggregates over a large area. Additionally, apply 1-2 coats of PM-101 penetrating sealant for sealing treatment.



Clean, dry asphalt surfaces in good functional condition require no sealing treatment.
