The Basic Screen Screed Kit (Part No. 2436327) is an essential paving component designed for the AB220-3TV asphalt paver, ensuring proper material distribution and surface smoothness
during road construction. This kit plays a fundamental role in
forming the asphalt mat by leveling and pre-compacting the mix
before final rolling. Below is a detailed exploration of its
purpose, key characteristics, and operational significance.
1. Introduction to the Basic Screen Screed Kit
The screed is the rear assembly of an asphalt paver that shapes and
partially compacts the hot mix asphalt (HMA). The Basic Screen Screed Kit for the AB220-3TV model provides a simplified yet effective solution for contractors who
require reliable performance without complex adjustments.
Key Functions
Material Spreading: Evenly distributes asphalt across the paving width.
Initial Compaction: Provides slight density to the mat before roller compaction.
Surface Smoothing: Helps eliminate minor irregularities for a uniform finish.
2. Key Features and Design Attributes
A. Simplified Yet Effective Construction
Durable Frame: Built to withstand continuous exposure to high-temperature
asphalt.
Standard Width Compatibility: Designed to match common paving requirements.
Bolt-On Design: Allows for straightforward installation and removal when needed.
B. Operational Efficiency
Consistent Mat Formation: Ensures uniform thickness across the paved surface.
Minimal Adjustments Needed: Ideal for projects requiring straightforward screed
functionality.
Compatibility with AB220-3TV: Engineered specifically for this paver model for optimal fit and
performance.
C. Wear Resistance and Longevity
3. Role in Asphalt Paving Operations
The Basic Screen Screed Kit contributes to paving efficiency in several ways:
A. Mat Formation and Consistency
B. Surface Finish Quality
C. Operational Flexibility
4. Importance in Paving Quality and Efficiency
A properly functioning screed is critical because:
Poor Leveling leads to uneven pavement, increasing roller passes and labor
costs.
Inconsistent Thickness causes premature road wear and potential failure.
Material Segregation (uneven aggregate distribution) weakens pavement structure.
The Basic Screen Screed Kit helps mitigate these issues by providing a reliable, no-frills
solution for consistent mat production.
5. Common Applications
This screed kit is typically used in:
Residential Street Paving: Where simplicity and efficiency are prioritized.
Parking Lot Construction: For smooth, uniform surfaces.
Road Repair and Maintenance: Quick patching and overlay work.
6. Maintenance and Best Practices
A. Routine Inspection and Care
Check for Wear: Examine screed plates and leveling bars for excessive wear.
Clean After Use: Remove asphalt buildup to prevent hardening and operational
issues.
Lubricate Moving Parts: Ensure smooth adjustment mechanisms.
B. Troubleshooting Common Issues
Uneven Mat Thickness: May indicate worn screed components or improper setup.
Streaking or Gaps: Often caused by clogged screed plates or misalignment.
Excessive Drag: Could mean incorrect angle settings or asphalt temperature
issues.
C. Replacement Considerations
Always verify compatibility with the AB220-3TV paver (Part No. 2436327).
Follow manufacturer guidelines for installation to ensure proper
function.
Consider upgrading to more advanced screed systems if project
demands increase.
7. Conclusion
The Basic Screen Screed Kit (Part No. 2436327) for the AB220-3TV
asphalt paver provides a cost-effective and reliable solution for standard
paving applications. Its durable construction, ease of use, and
compatibility make it a practical choice for contractors who need
consistent performance without complex adjustments.
By maintaining this component properly and addressing wear issues
promptly, paving crews can ensure high-quality asphalt mats, reduce
rework, and enhance overall project efficiency.
For optimal results, always use genuine replacement parts and
adhere to recommended operating procedures.
