Thus, storage stable SBS modified asphalt
was obtained by dynamic vulcanization.
Four kinds of AC-20 (Asphalt Concrete whose nominal maximum size of aggregate is 20 mm) asphalt mixtures and two kinds of AC-13 (Asphalt Concrete whose nominal maximum size of aggregate is 13 mm) asphalt mixtures (namely, AC-20 coarse-type modified asphalt
, AC-20 coarse-type matrix asphalt, AC-20 fine-type modified asphalt
, AC-20 fine-type matrix asphalt, AC-13 modified asphalt
, and AC-13 matrix asphalt) were designed according to highway project to research the influence of experimental conditions on APA rutting tests.
The 7th Rubber Modified Asphalt
Conference, organized by the Rubber Manufacturers Association (RMA), will take place November 2-3 at the Sheraton Ann Arbor Hotel in Ann Arbor, MI.
Based in Candeias (Bahia), Brazil, Betumat reportedly offers a full line of waterproofing products, including asphaltic membranes, cementitious grouts and modified asphalt
products, to professional contractors and builders primarily in northern Brazil.
Others have modified asphalt
with recycled polyolefins or crumb rubber particles produced from scrap tires (9-12).
In order to compensate for the weakening of the bonding force between the coarse aggregates due to the increase of voids, SBS modified asphalt
was used as the binder.
Many states have experienced a vast number of problems in preparing pavements using the crumb rubber modified asphalt
For the level of modification (10% EPDM in HDPE) used here to illustrate this route, it is found that on the basis of linear viscoelastic properties, morphology, TFOT aging, Ring-and-Ball softening point, and Fraass breaking point, the 1% HDPE/EPDM modified asphalt
presents the most promising results.
The dynamic moduli of the modified asphalt
mixtures were fitted by master curves .
The Association of Modified Asphalt
Producers (AMAP) will hold its 17th Annual Conference and Technical Workshop at the Grand Hyatt in Seattle, WA, February 9-11.
