Dominant paving segment to face budget constraints Paving accounted for the largest end use for asphalt
in 2014 with 74 percent of consumption.
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.
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.

Sixteen new methods that distinguish behavioral characteristics of compositionally diverse petroleum asphalts
were developed or refined into new methods during this project.
According to Alon, the facility will be the first in West Texas to use ground tires to manufacture premium road asphalts
