Description
Technical field
The present invention relates to a kind of asphalt, particularly relate to a kind of high additive plantmix temperature regeneration asphalt and mix
Close material and preparation method thereof.
Background technology
High additive is hot in-plant reclaimed refers to that Bituminous concrete surface consumption accounts for more than the 25% of Colophonium total amount, current old drip
The blue or green volume plant-mix heat recycle technology less than 25% is the most ripe, and research to show that it has the poorest
In newly mixing the performance of asphalt, even to show more preferably at some aspect of performance；But for
Waste asphalt mixture (RAP) volume regenerating mixture more than 25%, to the evaluation of its performance and
Research does not the most draw conclusion that is definite and that generally acknowledge.Based on this, U.S. part state regulation is used as upper layer
Regenerating mixture in the volume of RAP do not allow more than 30%.Visible, for high RAP volume
Regenerating mixture cold cracking property and the worry of fatigue behaviour, regenerating mixture is applied to high
Level highway or in upper asphalt surface course time RAP volume receive strict restriction, this greatly constrains
The development of high RAP volume plant-mix heat recycle technology and application.
