About this document
Lignin Isolates as Natural Asphalt Binder by Mas Pram is a document available to read on EtoBox.
The document discusses utilizing lignin isolates from pine wood (Pinus merkusii) as a natural binder to reinforce asphalt. Lignin is extracted from pine wood and used as a polyol in polyurethane synthesis with MDI. Nine mixtures of lignin isolates and asphalt are made at varying ratios and tested for mechanical and thermal properties. Test results show the optimum mixture is 40% lignin isolates and 60% asphalt, which improves density, compressive strength, and water resistance compared to pure asphalt. SEM
