木质素及其衍生物在道路沥青中应用的研究进展
Progress in the utilization of lignin-based compounds for asphalt pavement applications
摘要
Abstract
Biomass,as a sustainable and renewable natural resource,is considered as the fourth largest energy source after coal,oil and natural gas.Among them,lignin,as a biomass material with abundant reserves,is rich in phenolics and aldehydes that give it the potential to replace petroleum-based materials.With the development of the concept of green road materials,the application of lignin and its derivatives in asphalt pavements has received widespread attention.Based on this,this paper reviewed the compositional sources of lignin,the progress of the application of lignin and its derivatives in asphalt and the use of lignin as a modifier to increase the elastic component of asphalt,which helped to improve the viscosity and resistance to permanent deformation of asphalt.In addition,lignin had an inhibitory effect on the generation of carbonyl groups in the oxidation process of asphalt,which can improve the aging resistance of asphalt.Lignin-based synthetic resins can further cross-link with asphalt to form a network structure and promote the curing of asphalt,improving the storage stability and aging resistance of asphalt.In addition,lignin-based synthetic resins had excellent physicochemical properties and good compatibility with asphalt,suggesting that they had the potential to replace part of the asphalt.It was suggested that future research should improve the utilization rate of lignin in asphalt and the substitution rate of lignin-based synthetic resins in asphalt to help the sustainable development of new green asphalt pavement materials.关键词
