Description

Introduction Bitumen Extraction

A Bitumen Extraction Apparatus determines the exact percentage of bitumen binder present in an asphalt paving mixture. Road construction laboratories rely on this centrifuge extractor to separate bitumen from aggregate through controlled spinning action and solvent washing. Engineers use the extracted data to verify mix design compliance before a contractor lays asphalt on site. This apparatus delivers fast, repeatable results.
