Advantages of Screed Bottom Plate

Maximum Wear Life

Outlasts OEM materials with harder, abrasion-resistant carbide overlay

Increased Production

Longer service life means fewer stops and more consistent output

Reduced Friction

Lower Heat Demand: Ideal for use with polymer-modified mixes

Quick Installation

Factory-mounted studs simplify mounting and reduce install time

Direct OEM Replacement

Custom-engineered to fit your existing equipment with zero modification

Basic Principles of Screed Bottom Plate

The screed bottom plate operates on the principle of floating on the asphalt mat. As the paver moves forward, asphalt flows from the hopper through the augers and under the screed bottom plate. The screed bottom plate's weight, combined with vibration or tamping action, creates initial compaction.

Tow Point Control

The tow points connect the screed bottom plate to the paver's main unit. These pivot points determine screed bottom plate angle and height. Most modern pavers use automated grade and slope controls at the tow points. Sensors and hydraulic cylinders adjust the screed bottom plate position thousands of times per minute to maintain target elevation and cross slope.

Heating Systems

Screed bottom plate heating keeps asphalt from cooling too fast or sticking to the plate. Gas burners, electric heaters, or both keep the screed bottom plate at an even temperature across its width. Proper heating ensures smooth material flow and reduces drag.

Vibration and Tamping

Screed bottom plates use either vibration, tamping bars, or both to consolidate asphalt. Vibratory screed bottom plates create high-frequency oscillations that help particles settle.

Screed Bottom Plate Ideal For

Coarse aggregate mix specs
Contractors needing extended wear life with fewer interruptions
Plants using modern asphalt blends with polymer additives

Maintenance of Screed Bottom Plate

● Regularly cleaning the screed bottom plates is the first step in maintenance.

● Regular inspections are crucial to identify any signs of wear, damage, or misalignment in the screed bottom plates.

● Proper alignment of the screed bottom plate is vital for achieving uniform mat thickness and smoothness.

● Appropriate lubrication of the screed bottom plate components is crucial for smooth operation and longevity.

● Screed bottom plates have a limited lifespan due to the harsh operating conditions and continuous wear they endure.

Packaging and Shipping

Optimized Packaging:	Customized packaging solutions protect against damage during transit.
Global Logistics:	Efficient shipping options, including air and sea freight, ensure timely delivery worldwide.
