Highway and Roadway Trench Drain Systems

application image

High-Strength, Heavy-Duty, and Long-Lasting Linear Drainage for Transportation Infrastructure.

Highway drainage is a safety system first—and an asset-protection system second. When runoff isn’t captured fast enough, risks include hydroplaning, splash/spray visibility issues, and freeze-thaw damage that leads to early pavement failure. Linear trench drains are the essential tool for continuous interception in constrained, high-consequence locations like tunnels, bridges, and toll plazas.

Requirements Engineering for Highway Trench Drain Systems

Roadway drainage must be engineered for high-repetition wheel loads, dynamic impacts, and constant exposure to aggressive chemistry.

Functional Requirements

Continuous Interception:

Systems must provide capture where point inlets are constrained by barriers, utilities, or geometry.

Runoff Collection Efficiency:

Design focuses on capture spread and gutter flow to prevent hazards on the pavement.

Debris Tolerance:

Channels must maintain performance even when subjected to sediment, leaves, and road grit.

Environmental Requirements

Chemical & Deicer Resistance:

Must withstand constant exposure to chlorides and aggressive runoff chemistry.

Freeze-Thaw Stability:

Required to resist cycling at the grate and frame interface without structural failure.

Plow Abrasion:

Systems must include features to protect edges from snowplow blade strikes.

Mechanical Requirements

High Repetition Loading (Fatigue):

Engineered to withstand constant heavy wheel loads over decades of service.

Dynamic Impact:

Drains must remain stable during braking, expansion joint transitions, and roadway roughness.

Extreme Load Capacities:

Recommended Load Class D / E / F (per EN 1433) or HL-93 (per AASHTO) for highway traffic.

Material Selection Criteria

Roadway materials are selected for dimensional stability and the ability to act as a complete, pre-engineered assembly.

Channel Material (Polymer Concrete): Preferred for roadway work because it is durable, dimensionally stable, and integrates with heavy-duty frames.

Grate Material (Ductile Iron): The standard for heavy-duty traffic zones due to its impact resistance and longevity.

Secure Locking: Systems must feature positive grate locking (anti-rattle and anti-lift) to ensure safety under high-speed traffic.

Site Conditions to Evaluate

Hydraulic Spread

Evaluate how much water is on the pavement vs. the efficiency of the linear capture.

Sediment & Maintenance

Road runoff carries rubber fines, metals, and winter sand that require managed maintenance plans.

applications image

Pavement Interface

Trench drains act as a "hard discontinuity"; jointing and concrete haunch thickness must be evaluated to prevent cracking.

Typical Highway Configurations

Sag-Point Collection

Installed at low points and underpasses to prevent ponding and hydroplaning.

Toll Plazas & Weigh Stations

High-repetition zones that require maximum torsion resistance and continuous capture.

Bridge Approaches

Intercepts runoff before it enters critical structural zones or crosses expansion joints.

Barrier-Adjacent Runs

Used where curb inlets are unfeasible due to space or utility constraints.

Product Recommendation

Heavy-Duty Modular Polymer Concrete Systems

are the recommended choice for most roadway linear needs. These pre-engineered assemblies offer repeatable performance, consistent flow lines, and integrated accessories like in-line pits for sediment management.
