Access roads are often built in remote regions, where aggregate is scarce and must be imported at high cost. Haul roads need to support very heavy loads/vehicles without failure. Temporary service roads need to be built fast in all-weather conditions, yet with sufficient strength for heavy vehicles. The relative weakness of unbound granular material used for infill often necessitates thick pavement layers and extensive earthworks. PRS-Neoloy™ is stronger, greener and more cost-effective than any other ground stabilization solution for unpaved access road construction.
PRS-Neoloy access road solutions improve the structural integrity of soils in roadways, slopes by reinforcing and confining fill materials and distributing load forces. Hi-strength geocells are the answer for geotechnical engineers, road designers, developers and contractors facing the challenges posed by heavy loads that need to pass over soft subgrades.
Unmatched by other ground improvement solutions, access roads constructed with PRS-Neoloy reinforcement are ideal for transporting heavy equipment and vehicles to remote sites. Service roads for transportation to power project sites, oil and gas pipeline and utility maintenance. Temporary roads used for infrequent access or for road construction projects
Advantages of PRS-Neoloy Geocells for Access Roads
- FAST DEPLOYMENT – simple logistics, fast, all-weather installation
- TOUGHNESS – strongest and most durable geocell available
- ANY SOILS – use locally (low quality) available granular material for infill
- ANY ENVIRONMENT – deploy on any subgrade type, peat, sand, permafrost
- ANY CLIMATE – withstands hottest and coldest temperature extremes
- PHOTOCHEMICAL DURABILITY – highly resistant to UV, oxidation, leaching
- MULTI-FUNCTION – asphalt roads, temporary bypass and construction roads, embankments, drainage ditches, flyover slopes, retaining walls
SUSTAINABLE – low cost, use local materials, long lifespan, no or low maintenance
- Reduce road layer thickness and infill (by up to 50%)
- Improve elastic modulus of road base layer with inferior infill by 3x or more
- Increase design life of road
- Loads distributed over a wider area
- Decrease settlement by up to 50% and reduce vertical stress to the subgrade by up to 50%.
- All weather construction and all-weather use
- Reduce aggregate, hauling and placement costs
- Reduce repairs, long-term maintenance, operating costs
- Lower initial construction costs and Total Cost of Ownership
- Use of marginal and recycled infill reduces quarrying, hauling and carbon pollution
- Reduce road dust and sedimentation – low environmental footprint
- Self-draining system for reliable transport
