Roads Maintainence TRIZ Cases
- Mobile Road Repair Unit With Adjustable Blade-Cylinder Gap Control
A displacement-reduction mechanism controls the blade-cylinder gap to spread 1–3 mm aggregates accurately while limiting waste.
- Reactive Cold-Applied Thermoplastic Bond Coat for Asphalt Adhesion
A reactive polyacrylate bond coat cures cold, remelts during asphalt compaction, and limits interface voids and water penetration.
- Sensor-Guided Road Construction Machine Steering for Curved Alignment
A lever sensor and controller automate steering along roadway structures, improving contour alignment and reducing operator burden.
- Path-of-Travel Slope Control for Stable Asphalt Compactor Vibration
A grade sensor guides vibration, speed, and braking changes to stabilize asphalt compactors and improve mat uniformity on slopes.
- Road Paving Machine Pivoting Side Plates for Bend-Leveling Access
A pivoting side plate lets the screed align with road boundaries and level paving material near bends without obstruction.
