High-Volume Portable Paving and Infrastructure

RexCon Model S Overview

The RexCon Model S is the heavy portable paving plant in the lineup. Astec describes it as a portable paving batch plant built for portability, volume production, and quality mixing, with modular sections that are pin-connected for fast installation on the job site.

For Texas DOT paving, airport paving, industrial slab work, and large infrastructure packages, the Model S is the page buyers should land on when they search for a high-production portable concrete batch plant rather than a compact mobile yard plant.

When This Plant Is the Right Fit

You need a portable plant for volume paving, not just occasional ready-mix backup.

You want central-mix concrete quality close to the project site.

You need fast setup compared with a fully custom stationary plant.

You are bidding DOT, airport, roadway, or heavy civil work where sustained production wins the job.

Texas Application

The Model S is a strong fit for Texas contractors working long highway pours, major metro infrastructure, airport work, and large industrial paving packages where trucking from a distant permanent plant hurts cycle time.
