POLYMER MODIFIED ASPHALT
|
REDD Engineering has special expertise in PMA blending for a wide variety of applications. Our design flexibility will reflect your company's needs regarding key design parameters such as capacity, level of automation, equipment preferences, etc. to ensure complete customer satisfaction. REDD's process utilizes our proprietary technology and most recent developments in chemical formulation and equipment configuration. Our design can be highly automated to allow blending a wide variety of polymers into a wide variety of asphalt basestocks. Our process has flexibility to minimize modifier and operating costs while maximizing product value. |
Key advantages of using a REDD system are as follows
:|
Proprietary Design - REDD's formulation and design provide the highest flexibility and efficiency available by minimizing the quantity of polymer and/or additives required to meet or exceed specification requirements. Flexibility - REDD's equipment configuration allows for a PMA plant capable of blending 3% to 15% of EVA or SBS polymer concentrates into a wide variety of asphalt basestocks at 200 0C, with 60 0C test viscosities of up to 200,000 poise. Our equipment can be designed to process from 250 to 1400 tons per day of PMA, and heats asphalt to the required mix temperature. Automated Process - REDD's design controls the polymer addition rate automatically, maintaining the desired polymer concentration based on the asphalt flow rate into the mixing tank. REDD's automated process provides improved metering and regulation versus manual versions. Thorough Polymer Dispersion - REDD's process incorporates a combination of high temperature, high-shear mixing, and automation that provide a thoroughly dispersed polymer. Avoiding Phase Separation - The chemical formulation used by REDD impedes phase separation. Both mechanical and chemical measures are used in REDD's design to provide a stable, homogeneous, blended PMA product. AST's proprietary design allows the polymer to "network" within the asphalt, creating a homogeneous mixture. |
