Heavy Duty Ground Protection Mats
BKM manufactures two heavy-duty systems for demanding sites: 38 mm solid composite UHMWPE road mats and 102 mm large-format hollow-core polyethylene roadway panels. Both are built for temporary access roads, heavy equipment routes, work pads and all-weather construction access.
Heavy Duty Ground Protection Mats for Temporary Roads and Heavy Equipment
Heavy duty ground protection mats create a stable, reusable running surface where trucks, excavators, cranes and tracked equipment must cross mud, soft soil or sensitive ground. The panels spread traffic loads over a wider area, keep vehicles on a defined route and reduce the deep rutting that increases recovery time and site reinstatement costs.
BKM offers a solid plate system for configurable tracks and pads, plus a deep hollow-core composite system for connected full-width roadways. The correct choice depends on the ground, axle or track load, number of passes, turning behavior and required road layout.
Two Heavy-Duty Access Mat Systems for Different Ground Conditions
Choose the panel structure around the site and roadway layout—not from a single tonnage number.
Solid Composite UHMWPE Heavy Duty Road Mats
BKM-01 and BKM-02 are one-piece composite UHMWPE road mats made for tracked vehicles and heavy construction traffic. Both use a 38 mm solid body and measure 48 mm overall with the molded traction texture, with a reference load capacity of 120 tonnes under the stated product conditions.
BKM-01 measures 3000 × 2500 mm and weighs 293 kg; BKM-02 measures 4000 × 2000 mm and weighs 312 kg. Their different footprints allow the road layout, handling plan and container utilization to be matched to the project.
- Composite UHMWPE construction
- 38 mm body thickness
- 48 mm overall with texture
- 120-tonne reference capacity
- Black standard color
- 2-way and 4-way connectors
Hollow-Core Heavy Duty Composite Roadway Mats
BKM hollow-core composite mats use a deep cellular body with internal reinforcement. The structural section is designed to increase panel stiffness without using a completely solid block at the same overall depth, while large-format coverage reduces the number of joints across a temporary road.
Each panel has transport dimensions of 4350 × 2430 mm and provides a usable installed surface of 4160 × 2240 mm, equal to 9.31 m². Eight mechanical connection bolts secure each panel within the roadway layout.
- Polyethylene construction
- 102 mm total thickness
- 465 kg panel weight
- 9.31 m² usable coverage
- 8 connection bolts per panel
- Beige standard color
Solid Composite UHMWPE Access Mats in Greater Detail
The confirmed solid range comprises two composite UHMWPE formats with the same 38 mm body, 48 mm textured overall thickness and 120-tonne reference load capacity. These 293–312 kg panels require mechanical handling and are intended for industrial routes—not lightweight hand-laid lawn protection.
Each 293 kg panel covers a nominal 7.50 m². Reference loading is 26 panels in a 20GP or 72 panels in a 40HQ, equal to 195 m² or 540 m² of nominal panel area.
Each 312 kg panel covers a nominal 8.00 m². Reference loading is 43 panels in a 20GP or 87 panels in a 40HQ, equal to 344 m² or 696 m² of nominal panel area.
The specification distinguishes the structural body thickness from the overall thickness measured across the traction texture, preventing the two figures from being confused during comparison and inspection.
The material and molded surface are specified for tracked-vehicle applications. Black is standard; custom colors are available subject to minimum order quantity.
Large Hollow-Core Composite Mats as a Connected Road System
The hollow-core range uses a 102 mm structural depth and internal reinforcement to create a large-format polyethylene roadway panel. Each 465 kg panel is installed mechanically and joined with eight connection bolts.
Internal ribs support the upper and lower skins and help transfer rolling loads through the panel footprint without using a fully solid block at the same overall depth.
The specified bolt quantity must be included in roadway planning, spare-accessory quantities and installation checks so adjacent panels remain secured throughout use.
The selected BKM model is reviewed for shell construction and sealing requirements. Polymer panels do not rot like timber and can be pressure-cleaned, inspected and prepared for reuse.
Forklifts, excavators or cranes position each panel. The 4350 × 2430 mm transport footprint becomes a 4160 × 2240 mm usable surface in the installed layout.

Solid vs Hollow-Core Heavy Duty Composite Mats
Both systems create reusable heavy equipment access, but they solve different route and ground-condition requirements.
| Decision Factor | Solid Heavy Duty Mat | Hollow-Core Composite Mat |
|---|---|---|
| Construction | Solid composite UHMWPE plate | Polyethylene hollow-core body with reinforced internal structure |
| Format | 3000 × 2500 mm or 4000 × 2000 mm | 4350 × 2430 mm transport size; 4160 × 2240 mm usable size |
| Road layout | Wheel tracks, lanes, turning zones and pads | Continuous full-width roads and platforms |
| Connection | External 2-way / 4-way links | 8 mechanical connection bolts per panel |
| Ground conditions | Prepared, firm or moderately soft ground | Soft, wet, muddy and variable subgrades |
| Main advantage | 120-tonne reference load capacity with documented container quantities | 9.31 m² usable coverage from each connected panel |
| Handling | Mechanical handling; 293–312 kg per panel | Mechanical handling; 465 kg per panel |
The project needs defined wheel tracks, prepared-to-moderately-soft ground, localized turning areas or one of the confirmed 3000 × 2500 mm and 4000 × 2000 mm solid UHMWPE formats.
The priority is a large-format, full-width continuous road over soft, wet or variable ground with repeated heavy rolling traffic and controlled seams.
A hollow-core main route needs solid custom transition panels, expanded work zones or project-specific pieces at entrances, intersections and equipment areas.
How Heavy Duty Road Mats Carry Equipment Traffic
A temporary roadway works by spreading tire or track pressure through the panel into a larger area of supporting ground. Gross vehicle weight is only the starting point: axle load, contact area, turning, braking, repeated passes and soil strength determine how the system behaves.
Multiple axles do not load every panel equally. BKM reviews the heaviest axle group and tire contact footprint.
Track width spreads vertical load, while grousers and counter-rotation can introduce high local wear and lateral stress.
Steering, braking and acceleration create shear forces that require wider layouts and secure connections.
A single controlled pass differs from hundreds of daily passes or long-term parking on the same area.
Load Path Through a Temporary Road
The mat distributes pressure; it does not manufacture bearing capacity or safely bridge an unsupported trench. Model ratings must always be read with the installation and subgrade assumptions.
Heavy Duty Temporary Roadway Layouts
Quantity planning starts with the whole route: usable connected coverage, traffic direction, turns, passing points, work areas, transitions and spare panels.
Single-Lane Temporary Access Roads
A full-width one-way route keeps wheels or tracks within the connected mat surface. Road width is set from vehicle width, steering movement and a safe edge allowance—not from panel width alone.
Straight routes · controlled direction · defined entryTwo-Way Roads and Passing Bays
High-traffic sites may need a wider two-way road or planned passing bays. Extra coverage is allowed at waiting points so stopped vehicles do not load an unsupported shoulder.
Two-way traffic · passing areas · waiting zonesHeavy Equipment Work Platforms
Panels can expand from a road into equipment staging, laydown, maintenance or general working areas. Platform geometry follows machine movement and the location of concentrated loads.
Staging · laydown · maintenance · general work padsTransitions, Turns and Road Ends
Entry ramps, braking areas, intersections and tight turns receive more shear force than straight travel. These zones need additional width, secure connections and more frequent inspection.
Entry ramps · intersections · braking · turning
Interlocking Systems for Heavy Duty Temporary Road Mats
Connectors keep the temporary road aligned as vehicles cross panel seams. BKM matches the connection method to the panel structure and the width of the required roadway or work platform.
2-Way Connectors for Straight Access Roads
Join solid road mats edge to edge along a linear wheel path, equipment track or single lane.
4-Way Connectors for Work Pads and Wide Roads
Secure four panel corners where the layout expands into passing areas, turning zones or equipment platforms.
Eight-Bolt Connections for Hollow-Core Panels
Each hollow-core panel uses eight mechanical connection bolts. The specified quantity must be installed and checked to control gapping, drifting and panel movement.

Ground description changes the panel recommendation, base preparation, supported road width and inspection plan. The full-width site image remains fixed while the conditions below move across it.
Mud and Saturated Soil
Hollow-core first evaluationUse a connected full-width route, control drainage and assess whether geotextile or a prepared layer is needed beneath the panels.
Sand and Loose Fill
Wide solid or hollow-core layoutIncrease the supported width and limit edge loading, sharp steering and sudden braking that can displace loose material.
Wetlands and Marshes
Hollow-core continuous roadwayPlan access, environmental separation, retrieval and cleaning before installation; follow all project-specific environmental requirements.
Grass and Sensitive Surfaces
Select by load and durationKeep vehicles on the planned route and consider heat, moisture, duration and recovery requirements as well as the machine weight.
Frozen Ground and Snow
Impact-resistant formulationReview low-temperature material performance, traction, hidden voids and the change in bearing condition when the ground thaws.
Uneven or Prepared Subgrade
Solid mats often suitableRemove sharp projections, fill major depressions and prevent panels from rocking across unsupported high and low points.
Slopes and Crossfalls
Project-specific assessmentEvaluate lateral movement, anchoring, runoff, braking and rollover risk. Mats do not make an unsuitable slope safe by themselves.
How to Install Heavy Duty Temporary Road Mats
Both systems on this page require planned handling. The construction background remains fixed while the nine installation stages scroll through the foreground.
Survey the route
Record soil condition, drainage, slope, soft spots, underground constraints and environmental limits.
Plan traffic and layout
Define travel direction, road width, turns, passing bays, work areas, entrances and exits.
Prepare the surface
Remove sharp debris and fill major voids; add geotextile, drainage or a prepared layer when required.
Set the first panel row
Square and align the starting row because every following seam follows this reference.
Connect each panel
Install the specified 2-way or 4-way links for solid mats, or all eight connection bolts required for each hollow-core panel, before opening the route.
Build transitions and turns
Widen and reinforce entrances, road ends, intersections, braking zones and tight turning areas.
Complete a test pass
Use a low-speed controlled pass and check rocking, seam movement, edge support and traction.
Inspect during operation
Adjust the inspection frequency to rainfall, traffic volume, turning, braking and ground movement.
Remove, clean and stack
Lift with approved points, clear connectors, wash the panels and stack them evenly for the next project.
Cleaning, Inspection, Storage and Reuse
Reusability depends on what happens after the road closes. Cleaning the tread and joints, identifying damage and stacking panels on even support protects the next installation and the long-term return on the mat fleet.
Remove mud, aggregate and organic material from tread, overlaps, connector holes and lifting points.
Check cracking, permanent deformation, deep wear, damaged edges, distorted holes and loose internal components.
Clean and count links, bolts and anchors; replace bent, cracked or excessively worn hardware before redeployment.
Support the panel stack evenly and keep damaged or unverified mats separated from ready-to-use inventory.
Use the approved lifting points and equipment; avoid dropping panels or dragging connection edges across hard ground.
Project markings, serial identification and inspection records help dealers and contractors manage reuse between sites.

Shipping and Project Quantity Planning for Heavy Duty Road Mats
A useful quotation combines the roadway layout, effective connected coverage, connectors, spare panels, packing method and unloading resources.
Calculate the Connected Route, Not Just the Ground Area
Then add panels for entrances, road ends, corners, intersections, passing bays, work pads and site spares. Nominal transport footprint can overstate coverage where connected edges reduce usable dimensions, so BKM uses the approved installation drawing.
Use 9.31 m² per installed hollow-core panel. For solid mats, nominal panel area is 7.50 m² for BKM-01 and 8.00 m² for BKM-02.
Include 2-way or 4-way connectors for the solid layout. The hollow-core specification requires eight mechanical connection bolts per panel, plus an agreed spare quantity.
Add turning zones, passing bays, equipment platforms, transitions and replacement panels to the straight route.
BKM-01 loads 26 pcs in a 20GP or 72 pcs in a 40HQ. BKM-02 loads 43 pcs in a 20GP or 87 pcs in a 40HQ.
Confirm pallet, timber separator, strap, edge protection, accessory crate and unloading sequence.
Verify forklift capacity, crane reach, lifting accessories, laydown space and the order in which roadway panels are needed.
