Roads Maintainence TRIZ Cases

Continuous vehicle-position detection automatically adjusts conveyor angle and speed to keep milled material on the truck bed and avoid collisions.

Stored transverse inclination models let road-milling machines control depth accurately without a reference surface on one side.

Vehicle detection automates hopper opening and closing on a road paver, reducing operator workload and preventing material supply delays.

A pre-driven stake with a disk and support bar fixes screed-board depth, preventing dips and simplifying concrete leveling cleanup.

Real-time surface texture sensing lets a road construction machine vary asphalt placement by location, reducing waste and uneven application.

Continuous milling, heating, oil coating, and mixing create a uniform recycled asphalt mix that improves repaved road quality and lifespan.

An adjustable channel plate extension forms a defined screw trough to stop asphalt mix flowing forward while preserving road paver ground clearance.

Steering-based screw speed adjustment keeps paving material distribution uniform during direction changes, improving road surface quality.

A sealed vibrator assembly with resilient bands, fins, and grooves limits oil leakage and overheating while maintaining concrete tool vibration.

On-site mixing with helical stirring and integrated paving cuts road space use, prevents concrete setting, and speeds polyurethane pavement work.

Total station prism data maps paving mat edges so compactor machines can follow precise pass plans that improve compaction efficiency and accuracy.

A non-coplanar screed levelling member uses the laid slab as a guide to set depth and direction for uniform paving and drainage.
