What is the function of polyethylene road mats ?

Polyethylene road mats (usually also known as temporary road pad or subgrade plate) is a very important engineering auxiliary material, mainly made of high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMW-PE).
Its core function can be summarized as: quickly creating a temporary, sturdy, and reliable passage on weak and uneven ground, providing support for the passage of heavy equipment and vehicles, while protecting the surface environment below.
The following is a detailed breakdown of its specific function:
1、 Core function: Provide temporary access platform
Supporting heavy loads
Application scenarios: In construction sites, oil fields, gas fields, wind power projects, outdoor concerts, celebration events, etc., the ground may not be able to withstand the pressure of heavy machinery (such as cranes, excavators, cement pump trucks) or dense pedestrian traffic.
Function: Polyethylene road mats disperse the concentrated load of vehicles or equipment over a larger area, preventing them from getting stuck in mud, sand, grass, or soft soil, ensuring operational safety and efficiency.
Create a stable workspace
Application scenario: During construction or survey on soft foundation road sections, swamps, riverbanks, etc.
Function: After laying the road mat, it instantly transforms the unstable surface into a flat and sturdy work platform, providing safe and reliable operating space for equipment and personnel.
2、 Protective function: to protect the surface and ecological environment
Protecting vegetation and soil structure
Compared with traditional gravel paving, polyethylene road mats are directly laid on the ground, greatly reducing soil compaction and vegetation damage. After the event, remove the road mat and the surface can quickly restore its original appearance.
This is crucial for areas such as farmland, golf courses, parks, and nature reserves that require protection of the surface environment.
Prevent soil compaction and soil erosion
Repeated crushing by heavy equipment can severely compact the soil, damaging its breathability and permeability, and affecting subsequent ecological restoration. Roadmats avoid this.
On rainy days, it can effectively reduce the agitation of vehicles on muddy ground, prevent soil erosion and muddy roads.
3、 Economic and efficiency advantages: cost and time savings
Rapid deployment and recycling
Polyethylene road mats adopt a modular design, usually with connecting pins, which can be quickly assembled and disassembled like a puzzle, greatly saving labor and time costs for laying temporary roads.
It can be reused hundreds of times, and the comprehensive cost of long-term leasing or purchasing is much lower than repeatedly laying and cleaning gravel roads.
Reduce cleaning and maintenance costs
After the event or project is completed, it can be directly lifted and transported away without the need to clean up a large amount of gravel and debris, and there is almost no cost of environmental restoration in the later stage.
Reduced the cost of lost time and rescue expenses incurred when equipment gets stuck in a quagmire.
