How to Construct Polymer Cast-in-Place Diamond Tactile Paving with Colored Asphalt Permeable Pavement

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


Product Description: Polymer cast-in-place diamond tactile paving is a continuous tactile paving system made on existing pavement using inorganic high-strength polymer materials and specialized molds, available in two types: guiding strips and guiding dots. Standard widths are 300mm, 400mm, 500mm, and 600mm, with flexible customization 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 pavements.

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 - Inspection - Opening to traffic - Final acceptance.

2.2 Construction Equipment and Tools

The diamond tactile paving construction process 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, multi-step, multi-material coordinated construction system. Before construction, check the consistency of materials and compatibility among various materials. 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 according to the mix ratio and method set for batch operations. Proceed with batch operations only after ensuring no obvious defects in curing.

2.4.4 Base layer conditions and treatment

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





For cement concrete pavement with strength below C25, the surface should be treated by milling, scabbling, grinding, sandblasting, or roughening (for new concrete), preferably exposing the aggregate over a large area. Additionally, apply 1-2 coats of PM-101 penetrating sealant for sealing treatment.



Clean, dry asphalt pavement in good functional condition does not require sealing treatment.
