In recent years, as green mining construction has made substantial progress, dust control and wastewater discharge management in nonferrous metal mines have been continuously strengthened, with road maintenance investment increasing year by year.

In nonferrous metal mines, haul roads are the “arteries” of production — from mining sites to processing plants, from waste dumps to stockyards, mining trucks operate from dozens to hundreds of trips daily. Under heavy-load rolling, road surfaces easily loosen, generate dust, and develop potholes. For enterprises, mine road maintenance is a “fixed cost.” Cement pavement has poor impact resistance, cracking and breaking within 2-3 years, with long repair cycles and high costs. Asphalt pavement softens and ruts in high heat, suffers water damage and peeling in rain, requiring at least one repair annually. Stabilized soil roads have limited load-bearing capacity. Road maintenance consumes significant operational time, affecting normal mine production.

Goodroad New Material Technology Co., Ltd.’s Flexible Film-Forming Technology breaks through the limitations of traditional mining road technologies that cannot simultaneously meet high load-bearing, water damage resistance, long life, and low maintenance requirements. “Traditional rigid pavement is like a ceramic bowl — hard but brittle. Flexible film-forming is like a car tire — it dissipates force through micro-elastic deformation under heavy pressure, making it much less prone to damage,” explained Liu Yi, General Manager of the company.

The core concept of Goodroad Flexible Film-Forming Technology is not simply “using a different material to pave roads,” but fundamentally changing the road’s failure mode through structural innovation. Its structure has three key features:

Dense Waterproofing: The flexible film layer forms a dense barrier, effectively blocking water from seeping into the subgrade, fundamentally preventing softening and mud-pumping issues.

Stress Distribution: The high ductility of the film structure enables it to absorb and distribute heavy-load impact stress, stably bearing single-axle loads of over 40 tons, avoiding the through-cracking and slab breakage common in rigid pavement.

Long-Lasting Dust Suppression: The film layer adheres and solidifies loose road surface particles, forming an integral membrane shell with a dust suppression rate of over 80%. No frequent watering is needed after construction.

Liu Yi noted that this “allows deformation without failure” characteristic means that after one application of Goodroad Flexible Film-Forming pavement, it can stably serve for 5–10 years, with only localized wear-area quick repairs needed — no large-scale reconstruction required.

Currently, Goodroad Flexible Film-Forming Technology has been practically verified in multiple mining scenarios. In the steel industry, after application on main haul roads at Jigang and Laigang, road service cycles were significantly extended, watering frequency dropped by over 80%, and transport efficiency improved notably. In the building materials industry, after Shandong Shanshui Group adopted the technology for its mining area roads, maintenance costs decreased by over 50% compared to traditional solutions.
