Dowel Bar Retrofit
Dowel Bar Retrofit systems supplied by Kasko Makine for concrete pavement rehabilitation, using epoxy coated dowel bars to restore load transfer across joints and cracks with high corrosion resistance.
Overview
Dowel Bar Retrofit is a proven pavement rehabilitation method used to restore effective load transfer across joints or cracks in concrete pavements. Kasko Makine supplies epoxy coated dowel bars manufactured with Fusion Bonded Epoxy powder coating to ensure high corrosion resistance and long service life.
Product & Manufacturing (As Provided)
Kasko Makine produces high-quality dowel bars specifically designed for retrofit applications. The epoxy coating protects the dowel bars from corrosion, making them suitable for long-term use in aggressive environmental conditions.
Retrofit Method & Purpose (As Provided)
Retrofitting dowel bars involves cutting slots across existing joints or cracks to install new dowel bars. The primary objective is to repair faulted joints or cracks and prevent the recurrence of pavement distress.
Load Transfer Principle (As Provided)
Load transfer refers to the ability of a pavement joint to distribute a portion of an applied load from one concrete slab to an adjacent slab. Higher load transfer results in more uniform load distribution to the subbase and subgrade, which significantly improves pavement performance and durability.
Performance Impact (As Provided)
Effective load transfer reduces pavement distress such as faulting, pumping, corner breaks, and spalling. Poor load transfer, by contrast, accelerates structural damage and shortens pavement service life.
Application Limitations (As Provided)
- Not recommended for joints or cracks that are already severely spalled
- In such cases, full-depth or partial-depth concrete patching is required before retrofit
Applications (As Provided)
- Concrete road and highway rehabilitation
- Airport pavements and industrial yards
- Joint and crack repair in rigid pavements
- Infrastructure projects requiring extended pavement life
Operational Benefits (As Provided)
- Restores and improves load transfer efficiency
- Enhances pavement structural performance
- Epoxy coating provides superior corrosion resistance
- Extends pavement service life
- Cost-effective alternative to full pavement replacement
