Compostos sulfurados em asfaltos: influência do processo de envelhecimento na composição das frações maltênicas e asfaltênicas
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-08-05)
The behavior of sulfur compounds in asphalt cements can be studied in a more comprehensive way through the separation of maltenes and asphaltenes and their respective fractions. Thus, the ASTM D4124 method was applied for ...
Degree of Influence of Active Fillers on Properties of Recycled Mixes with Foamed Asphalt
(SAGE PUBLICATIONS INC, 2009)
Active fillers in foamed asphalt mixes are added to modify the fine fraction of aggregate gradation or to reduce the moisture sensitivity of the mix. Some countries use cement as an active filler, and other countries use ...
