GR (GOODROAD)

MiningRoad GR (GOODROAD) Type Flexible Pavement Film-Forming Agent

FPF technology is a novel road construction technique that uses physical and chemical methods to treat the surface layer of compacted earth-rock roads, forming a flexible film-forming layer with functions including pressure resistance, wear resistance, waterproofing, and dust suppression.

This technology employs a "wet film formation" process, using locally sourced aggregates as a base and adding a film-forming agent developed from new mining road materials to rapidly form a composite structure film-forming layer.

The flexible film-forming layer not only possesses the pressure resistance and wear resistance of rigid pavements but also retains the advantages of low cost and rapid construction of earth-rock roads, becoming a third road construction mode between traditional hardened pavements and mud-bound gravel roads.

Features of Flexible Pavement Film-Forming Technology

On the basis of the original road surface, the flexible film-forming agent is gradually infiltrated into the original road surface through the "wet film-forming" construction process. The flexible film-forming agent reacts with the soil and stone particles or waste residues of the original road surface and gradually forms a flexible film-forming layer that is both flexible, tough and waterproof.

The flexible film-forming agent has certain biological activity characteristics: it can "press", "grow", and "resist pressure". As the vehicles continue to roll over, the sand and gravel aggregates and dust are pressed into the layer and become part of the layer, and the thickness gradually reaches more than 10mm. The increase in aggregates can resist the heavy pressure and friction of heavy-loaded vehicles.
The flexible film-forming agent also has the function of "slow release of dust suppressants". It contains bio-based dust suppressants and has a slow release function, which prolongs the use effect of dust suppressants.

Comparative Analysis of Benefits of Flexible Pavement Film-Forming Technology

Flexible Pavement Film-forming Technology

Differences Compared to Traditional Cement/Asphalt Pavement

Q: What are the advantages of flexible pavement film-forming technology compared with traditional cement/asphalt pavement? What are the main problems it solves?
A: Traditional cement/asphalt pavement has the following limitations:
1) High cost (40-100 USD/㎡).
2) The construction period is long (at least 1 month), which seriously affects road traffic.
3) Cement pavement is easily damaged by heavy vehicles (usually can use 2-3 years) and is not suitable for temporary roads such as mines.

Advantages of flexible pavement film-forming technology:
1) Based on the original foundation construction, it has both flexibility and strength, and excellent pressure resistance and waterproofperformance.
2) Low construction cost and fast forming speed.
3) Effectively solve the problems of dust, water damage, and uneven road surface on earth and stone roads.
4) Particularly suitable for temporary road needs, economical and efficient.
Service Life

Q: What is the service life of flexible film-forming pavement?
A: The service life depends mainly on the vehicle load and traffic frequency.
1) Under normal conditions: 10-15 years.
2) Heavy vehicles (over 50 tons) shorten the life of all types of pavement.

Compared with traditional pavement:
1) Cement pavement will develop irreparable cracks in 2-5 years under heavy load; when crushed by heavy vehicles, cement pavement is like glass, once broken, it cannot be repaired and can only be rebuilt.
2) Flexible film-forming pavement is made ofpolymer resin and bio-based materials, has self-healing functions, and can extend its service life through repair. Its principle is similar to the self-repair mechanism of the skin.
Routine Maintenance

Q: How to do daily maintenance? Is the maintenance cost high?
A: The maintenance method is simple and low cost.
1) Regularly clean up large pieces of debris from the road.
2) If there is foreign dust, clean it regularly or use a water truck to clean it.
3) If damage is found, repair it promptly with local materials (sand + GOODROAD agent).
4) Heavy-loaded sections need to strengthen daily maintenance.
Environmental Certification

Q: Is the material environmentally friendly? What certifications does it have?
A: Material composition: Environmentally friendly polymer materials and bio-based materials, non-toxic and non-flammable.
Certification status: The product has passed certification by the Chinese authoritative organization.
Dust Suppression Effect

Q: How effective is the dust suppression? How long is the effectiveness period?
A: Dust suppression is achieved in two ways:
1) Physical covering: The flexible film-forming pavement layer seals out dust.
2) Chemical dust suppression: The membrane contains a slow-release dust suppressant.
Note: It has a limited effect on large amounts of foreign dust, but it is better than traditional cement/asphalt pavement.
Material Properties

Q: What is the film-forming material? What road surfaces is it suitable for? How does the color change?
A:
1) Main ingredients: Polymer resin + crushed stone aggregate/waste residue material.
2) Applicable scenarios: Non-standard soil, stone and sand pavements.
3) Color change: Dark brown at the beginning of construction, gradually turning into light black with oxidation and rolling.
4) Packing specifications: Ton barrels.
What is the specific amount of flexible film-forming agent used in different transportation environments?

Standard Layer:
Technical specifications for flexible film-forming technology, the thickness of one film-forming layer shall be 8-10mm.
What Is The Basic Process Of Flexible Pavement Film-forming Technology Application?

1. Working condition review
2. Program formulation
3. Contract signing
4. Products preparation
5. Pavement maintenance
6. Pavement membrane
7. Uniform traffic
8. Post-maintenance
Why Does The Flexible Pavement Film-forming Technology Better Than Other Solutions For Mining Road Construction?
What Is The Thickness Of Flexible Pavement Film-forming Technology?

Initially forming a membrane layer with a thickness of 2-4mm. With continuous spraying, it possesses a strong dust suppression function, gradually thickening to 4-5mm, and in some areas reaching 6-8mm thick.
Why Is Road Quality Is Important In Mining?

First repair the road before repairing the vehicle; a mining road is better than a good vehicle, this is a saying often mentioned by mining transport owners.
1. Fuel consumption accounts for 35-40%
2. Tire replacement costs account for 10 - 13% (directly related to pavement smoothness and amount of water spraying)
3. Labor costs account for 10 - 15%
4. Equipment maintenance and parts costs account for 5-7 % (excluding tires)
5. Direct and indirect costs of road repair and maintenance account for 0.5-1.6%
6. The quality of the road directly and indirectly affects transportation efficiency by approximately 6 % or more
