GPC/SECApplication note(PSS Polymer Standards Service GmbHPSS Polymer Standards Service -USA IncFax: +1 413-835-0354www.pssgpcshop.com #10002-Characterization of Bitumen Bitumen is made from mineral oil and contains high molecular weight hydrocarbon mixtures. It ismainly used for protection of buildings (roofing and waterproofing), for street construction materialsand in roofing paper. Sample Preparation The sample was dissolved for 12 hours. The sample solution was filtered through a 0.45 pmmembrane filter to protect the columns.
