Study on How to Improve Asphalt-modified with SBS-added Carbon-nanotubes-material

摘要

Years recently,materials with Nano-techniques on highway-works have been studied.Asphalt modified with Carbon-nanotubes-material can be one of them.There are a great deal of π-type-conjugate bond and circled construction in them,they can easier bind to asphalt together with SBS than any other Nano-Inorganic material.This paper advances that a series of tests by putting SBS added with Carbon-nanotubes-material into asphalt are done at lab.The data show that the range of Carbon-nanotubes-material can be acceptable from 0.02-0.08％,meanwhile the asphalt-modified in the test can be comfortable with both the heat and the cold environment.Carbon-nanotubes-material can play a key role in the case of SBS added with it.
