Heatec Polymer Blending Systems

Astec provides equipment and services to build polymer blending systems. We were an early pioneer in producing systems to blend polymer with asphalt cement to make PMAC (Polymer Modified Asphalt Cement). PMAC is used as a binder in HMA (Hot Mix Asphalt). PMAC is also used to make asphalt roofing shingles to increase their life.

We can build your polymer blending system to meet your exact needs. Astec makes a variety of systems for blending polymers (including ground tire rubber) with virgin asphalt cement. Our systems are available in both fixed and portable configurations.

We can also upgrade an existing blending system. You may want to replace old or unreliable controls and equipment with new products. You may need to expand your plant to increase production volume.

Astec occupies a unique position for building polymer blending systems. We are virtually the only company that provides a full range of services, including system design, manufacturing, setup, startup, maintenance, etc.

This provides significant advantages for you, the buyer. You only have to work with a single source for the diverse products and services involved. And it greatly reduces the likelihood of costly reworks due to incompatibility and miscommunication.

The polymer most commonly used for HMA is SBS (Styrene-Butadiene-Styrene), which must be ground in a mill during the blending process. The blending process requires unusually high temperatures and constant agitation.

A stationary system that blends SBS polymer pellets with virgin AC (asphalt cement) is most commonly used at asphalt terminals.
