Research on Quantitative Evaluation Method for Permeability of High Permeability Temperature Regenerants
摘要
Abstract
At present,the permeability evaluation method of regenerator is not systematic,the test method is not accurate and the operation is complicated.Firstly,the aging asphalt was prepared by RTFOT delay aging method.Then,the data obtained from the contact angle test were used to make the scatter plot of the contact angle changing with time,and the key index of evaluating the permeability of regenerator,spreading rate b was obtained.Finally,the permeability test of two regenerants with known permeability was carried out to evaluate the permeability effect quantitatively,and the feasibility of the test method was demonstrated.It is suggested that the permeability of regenerant in RAP aged asphalt should be considered while verifying the regenerant's regeneration effect.关键词
