EZIV Highway Class Screed

Overview
The Carlson EZIV is the industry’s leading asphalt screed for award winning mat quality and wide width ability. Helping contractors to earn multiple Sheldon G. Hayes Awards and other accolades, the EZIV provides contractors a reliable, heavy duty screed platform for commercial, municipal and highway-class applications. Along with its single slide extension support system combined with heavy-duty, adjustable wear components, it is no wonder why the Carlson EZIV is recognized as a leading front mount screed.
Features
Screed Plates
The EZIV features Carlson’s exclusive 2% screed taper, facilitating great outboard flow of material towards the endgates whether the augers are in operation or not. Its 1/2” (13mm) Hardox 450 main and extension plates are combined with state-of-the-art heating elements for efficient, clean and even heat through use of full-length element hold downs. And with its optimized pivot point location, the EZIV achieves increased screeding surface, enhancing the smoothness and ride quality of the mat while maximizing screed plate lifecycle.
Single Slide Extensions
Utilizing a unique single slide extension support system, the EZIV drastically reduces component replacement costs while achieving exceptional rigidity of its extensions. The 2” (51mm) diameter chrome rods provide fluid inboard and outboard motion while the heavy-duty 6” (152mm) tubular frame that the rods are firmly fixed to bears the weight and forces on the extensions. Combined with the industry’s largest adjustable slide block bushing for front-mount screeds, the EZIV’s extension support system truly sets itself apart from the field in performance, component lifecycle and mat quality.
Adjustable Slide Track Bushing
Utilizing the largest adjustable slide track bushing in its class, the EZIV extension maintains integrity of the slide track function for reduced lifecycle costs and superior performance
Adjustment Points
The hallmark of Carlson’s front mount screeds are the intuitive adjustment points that maintain their hold for exceptional mat quality. The EZIV features a heavy duty, machined power crown assembly with pull pins for adjustment of lead crown on the fly. Combined with an exceptionally strong slope plate bolt pattern and slope stop that allows greater periods between adjustments, along with tightly fitted adjustable strike-offs, the EZIV delivers award winning mat quality while maintaining its adjustments over longer periods of time
Crew Comfort
Creating a safer, more productive environment for crews, the EZIV continues to set the standard for contractor focus. Featuring rubber isolated 20” (508mm) deep foldable walkways, the EZIV provides a comfortable and safe operating platform. And with its conveniently located cup holders, 110v outlets for accessories, depth rods and holders, shovel holders, clip board holder and legendary Carlson oven, no other screed can match the attention to the needs and wants of contractors like the EZIV
Unparalleled Mat Quality
The Carlson EZIV delivers a superior quality mat due to its 2% tapered screed plate for enhanced material flow, state-of-the-art heating elements for fast, even heat, intuitive adjustment points for simple leveling and innovative V3 endgate platform.
Wide Width
With its uncompromising extension rigidity, innovative bolt-on designs and easy installation, the EZIV is able to tackle wide widths up to 22’ (6.7m) (EZIV08) or to 26’ (7.92m) (EZIV10). Bolt-on extensions include 12” (305mm), 18” (457mm) and 24” (610mm) wide bolt-on’s, all standard with state-of-the-art heating elements and Y-cables. Enabling operators to easily set up for wide width applications with its hydraulically adjustable match height and accessibility of additional power, the EZIV simplifies wide width paving while delivering unmatched mat quality.
Standard Shoe
Through use of a simple bolt system, the Carlson V3 Endgate enables easy change of endgate runners to suit the jobsite application. Standard on all Carlson screeds, the V3 enhances crew safety, reduces downtime and increases productivity. The endgate comes with the Standard Shoe, and can be enhanced with an optional heat kit.
Carlson Safety Edge
The patented Carlson Safety Edge is the contractor’s choice for creating accurate, 30º extruded edges for safer, longer lasting roadways. Easily adjustable when approaching curbs and driveways, the attachment is the only endgate mounted Safety Edge builder approved by the Federal Highway Administration (FHWA).
