The present work seeks to identify the changes on the rheological, physical properties of the SBR- and SBR/sulfur-modified asphalts
by short-term and long-term ageing, to compare the SBR-modified asphalt
with the SBR/sulfur-modified asphalt
with the suitable sulfur content (0.
org as downloadable PDF files, each document summarizes a particular agency's asphalt
is one concern, as it contains coal tar pitch, a recognized human carcinogen, as well as polycyclic aromatic hydrocarbons (PAHs) including benzo[a]pyrene, another carcinogen.
The nonresidential building market for asphalt
will enjoy the best growth prospects over the forecast period, as construction activity rebounds from 2002 levels particularly in the office, commercial and industrial segments.
In addition to this resistance to change, Amirkhanian says that a lot of the hesitancy toward rubberized asphalt
has to do with the ISTEA Act of 1990.
concrete mix samples were prepared using the tire rubber modified asphalts
to evaluate the resistance to rutting and low temperature cracking.
Researchers, though, have found some good news about cracking: Asphalt
can actually repair itself to a certain degree.
Under this agreement, effective at closing during the second quarter 2011, Ergon A&E will continue to market all retail paving asphalt
from the Lion refinery in El Dorado, AR as well as from the asphalt
terminals in Henderson, TX and Muskogee, OK.
The applications of DSC analysis of asphalts
blends to evaluate interaction of the asphalt
components have previously been reported , and a comparison of DSC thermograms of polymeric materials and their asphalt
blends is shown in Fig.
The new plant will use Wright's Tire Rubber Modified Asphalt
Cement and Liquefied Tire Rubber technologies to combine recycled ground tires and asphalt
to create products that will be used to pave roads throughout West Texas and eastern New Mexico.
The binder qualities of conventional asphalts
cements) now produced by refineries need to be enhanced by adding chemical modifiers which improve performance under many types of loads and climactic stresses.
emulsions, cutback asphalts
, built-up and roll roofing, modified bitumen roofing, asphalt
shingles), new construction and maintenance/repairs markets, and geographic region.
At the Turner-Fairbank Highway Research Center (TFHRC), research on chemically modified asphalts
is an ongoing project that has already resulted in furfural-modified asphalt
, compatibilized crumb rubber asphalt
(CCRA), and chemically modified crumb rubber asphalt
(CMCRA), all of which were developed by the authors of this article.
By using chemically modified crumb rubber to improve the low-temperature rheological performance of CMCRA made from regular asphalts
, refiners potentially can save millions of dollars; savings that inevitably make CMCRA a more attractive product to users.
