Lime Road New Materials
Product Overview
The material (Limi-Layer Thin Coating, abbreviated as) LMLIt is a water-soluble, two-component, high-wear-resistant modified waterborne polymer material specifically designed for asphalt surfaces. It is currently the global leader in specialized asphalt and concrete surface materials. Developed over eight years in collaboration with Dow Chemical Company of the United States by Shandong Limei Road, this material has undergone nearly seven years of application and tracking tests. Adjustments to the formula and material functionalities have been made based on the unique environmental and climatic conditions of Yantai, resulting in a long service life, colorfastness, and high wear resistance. Non-delamination, low-temperature resistance, salt spray resistance, and other superior functions that are not achievable by any materials on the market today. It can effectively cover road cracks and depressions, reflect ultraviolet rays, reduce rain erosion, delay asphalt aging, and at the same time, it is perfectly compatible with asphalt..Midea's compatibility ensures that the surface layer will not crack or delaminate due to asphalt shrinkage, effectively reducing the urban heat conduction effect and lowering road temperatures. 5-7 degrees.
Product Features: Easy to install, durable, eco-friendly, resistant to chemical corrosion, color stable, high wear resistance, and good anti-slip performance.
Primarily applicable to: parks, amusement parks, pedestrian walkways, riverbanks, parking lots, squares, and roadways.
Material Description: The colored road material is a water-based two-component paint, non-toxic and free of irritating odors, and has passed international authoritative green construction safety assessment institutions (LEED certification inspection.

3. Product Features
This product boasts unique design, vibrant colors, exceptional performance, environmental friendliness, and the ability to beautify surroundings. Its high reflectivity to sunlight reduces road radiative heat and mitigates the urban heat island effect, effectively conserving energy.
（1) Eco-friendly: Passed the international authority's green building safety assessment (LEED) certification, water-based materials, non-toxic and odorless.
（2) Exceptional Performance: Features UV protection, reduces heat island effect, lowers pavement temperature, delays asphalt aging, and extends pavement lifespan.
（3) Unique Design: Using specialized infrared heating equipment, various three-dimensional road surface effects and decorative designs are molded onto the existing asphalt pavement, significantly enhancing the road's aesthetic appeal.
（4) Rich in Color: The abundant colors effectively compensate for the single color deficiency of traditional asphalt roads, beautifying the road landscape environment.
（5) Easy Construction: Directly installed on the existing asphalt road surface, with a short construction period and quick restoration of traffic.
（6) Excellent anti-slip properties: sharp.The combination application of high molecular polymer and high-intensity wear-resistant bone material effectively improves the anti-slip performance of the road surface.
（7) High extensibility: The polymer has the same expansion coefficient as asphalt, effectively preventing coating cracking.
（8) Strong Adhesion: Features excellent adhesion, suitable for use on iron products and cement surfaces.
（9) Eliminate Color Discrepancies: Capable of removing the new and old color discrepancies that may arise after road repair, maintaining the consistency of the road color.
(3) Construction Plan
Construction Process Flow
Original asphalt pavement→ Basic cleaning of garbage and dust → Small road cleaning vehicle washes the pavement once → Apply protective tape before construction → Spray the first.A colorless base binder with one coat→ Second coat of wear-resistant layer → Third coat of reinforced wear-resistant layer → Fourth coat of abrasion and alkali-resistant surface coating → Fifth coat of salt and alkali-resistant, UV-protective agent → Daily cleanup of site waste, protective tape, etc.
