Study on the Effect of Different Warm Mix Asphalt Additive on the Performance of Regeneration Asphalt and Its Mixture
Abstract
At present,the traffic development of our country has entered a new era,the resources waste and environmental pollution at highway engineering is gradually ing the history, when pavements are built or discarded old mate五al has gradually been recycled and is all important embodiment,when the people pursuit a beRer life。focusing on the solution to the harmony between mall and on the green development and exploring the new mode of sustainable development of highway engineering,for our country
from the large traffic nation to the powerful traffic nation to lay a solid foundation.
In this paper,old material,milied and recycled from an expressway surface in the Liaoning province,is the research object to do the tests of Warm—Recycled Mix meet road performance as the prerequisite,maximizing the blending rate of old material by designing different test using Warm Mix Asphalt technology to prevent causing new pollution to the environment and achieve a multiplier effect.
The laboratory test is the main research in this the aging asphalt from old material and make the recycled asphalt,three kinds of warm modified asphalt and three kinds of warlTl-recycled modified do the tests like ration,softening point,the rotational viscosity and infrared spectrum test for a11 the kinds of
analyze the mechanism of aging asphalt,recycled asphalt,warm modified asphalt and warln—recycled modified ,do the bending beam rheological test,and use Burgers mechanics model to fit creep stiffness data of BBR test with MATLAB software. analyze the low temperature performance of all the kinds of asphalt.
Extract and analyze the recycling of the old asphalt mixture,making AC一1 6 as target regeneration grade,tO determ
