Tensar Pavement Interlayers
Tensar Pavement Interlayers
Load Support System for Heavy-Duty Pavements
Presto GEOWEB distributes loads, reduces aggregate needs, and supports sustainable stormwater practices.
Tensar pavement interlayers redefine asphalt reinforcement with systems designed to control cracking, strengthen overlays, and extend pavement life. Created for both new construction and rehabilitation, these geosynthetic solutions reduce maintenance frequency and improve long-term stability by redistributing stress, mitigating reflective cracking, and optimizing structural performance in demanding traffic environments.
Engineered Systems for Overlay Strength
Tensar offers two specialized reinforcement technologies that combine material precision with proven field performance. Both are engineered to deliver reliable bonding, enhanced tensile strength, and effective crack control across a range of pavement conditions. Together, they establish a durable, integrated layer that resists deformation and improves overlay longevity.
- GlasGrid Pavement Reinforcement System: uses a high-tensile fiberglass grid with an open aperture design that bonds directly through the asphalt layer. Its polymer coating ensures adhesion and stress absorption, preventing slippage and extending overlay life in heavy-duty applications such as highways, airports, and industrial routes.
- GlasPave Waterproofing Paving Mat: merges a polyester paving fabric with fiberglass reinforcement to form a waterproof, crack-resistant layer. This composite barrier stabilizes subgrades and maintains overlay durability in light to medium pavements exposed to moisture and temperature variation.
- Field performance validation: shows that both systems achieve up to five times greater crack resistance than conventional overlays, with significant reductions in rehabilitation frequency and lifecycle costs.
Design Factors for Reliable Results
Every reinforcement project requires precise evaluation of structural design, traffic demand, and environmental exposure. Tensar systems adapt to these variables to ensure consistent performance across all pavement types and service conditions. Proper selection and installation deliver measurable improvements in strength, bonding, and protection over time.
- Overlays should begin at a minimum of 1.5 inches of compacted asphalt, or 2 inches in rut-prone conditions, to achieve adequate structural capacity.
- Traffic intensity and wheel load distribution guide the choice of reinforcement type and placement depth.
- Surface condition and base composition influence how effectively the interlayer bonds and mitigates reflective cracking.
- Sites requiring moisture protection benefit from the GlasPave system, which preserves subgrade stability and prevents water intrusion.
When correctly integrated, these factors create a reinforced pavement system that increases durability, improves surface performance, and extends service life across the full pavement network.
Proven Results in the Field
Independent testing and long-term installations confirm the superior performance of Tensar pavement interlayers in strengthening overlays and extending their useful life. These solutions go beyond reinforcement to redefine efficiency, reliability, and sustainability in pavement design.
- Reflective cracking reduced by up to fifty percent in overlays incorporating Tensar systems.
- Structural performance equivalent to several additional inches of asphalt, optimizing cost and material efficiency.
- Reduced maintenance cycles that extend asset life and lower total ownership costs for municipalities and private operators alike.
Tensar technologies have demonstrated decades of consistent performance across diverse environments, earning the confidence of engineers and contractors for projects that require dependable, lasting results.
Upstream and Downstream Structural Balance
Tensar interlayers perform as part of a balanced system that manages both load distribution and moisture flow from subgrade to surface. Correct installation alignment ensures consistent stress transfer and directional drainage, maintaining structural integrity under repeated traffic and thermal cycles.
- Reinforcement alignment enhances tensile continuity, preventing localized strain and ensuring even stress distribution across the pavement.
- Polymer coatings allow controlled lateral moisture movement while protecting the base from vertical infiltration.
- Integrated material interfaces stabilize the overlay structure through seasonal and traffic-related expansion and contraction.
- Coordinated reinforcement creates balance between subgrade stability and surface flexibility, reducing fatigue over time.
Tensar geosynthetics unify structure, stress, and drainage into a cohesive system that sustains alignment, preserves performance, and extends the lifespan of every roadway.
