Asphalt Extraction

Asphalt Extraction

Since 1994, Enviro Tech has continually aimed to become one of the top suppliers of safer, environmentally responsible, stabilized n-propyl bromide (nPB) solvents for industrial cleaning applications. And with EnSolv®, our versatile, EPA-approved nPB solvent cleaner, we have succeeded. Our signature product is ideal for use in a variety of asphalt extraction methods.

EnSolv®-EX Solvent for Asphalt Extraction

EnSolv-EX is a new-generation solvent for granular and bituminous extractions. It is an excellent choice as a safer replacement for hazardous solvents such as methylene chloride and trichloroethylene — and our EnSolv-EX is just as efficient and effective, if not more so.

EnSolv-EX is an azeotropic mixture that is 100 percent recyclable and reusable through numerous distillation cycles. In June of 2005, AASHTO approved n-propyl bromide, the key constituent of EnSolv-EX, as an asphalt extraction solvent per AASHTO T164. In addition, EnSolv-EX meets ASTM D2172 and has been exhaustively tested by the Federal Highway Authority as an alternative to more hazardous chlorinated asphalt solvents.
