Comparison of the n-Alkanes and Polycyclic Aromatic Hydrocarbons Concentrations in the Atmosphere during the Preparation of Warm and Hot Mixtures Asphalt for Pavements
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Asphalt binder is used in the production of hot mixes asphalt (HMA) for paving and, due to the high temperatures used, generates fumes thatcontainn-alkanes and polycyclic aromatic hydrocarbons (PAH). Asphalt mixes prepared ...
Marshall parameters for quality control of hot mix asphalt after pavement construction
(2019)
© 2019 Pontificia Universidad Catolica de Chile, Escuela de Construccion Civil. Highways have been and are built using Hot Mix Asphalt (HMA) as surface layer. The most common HMA design procedure is the Marshall Method, a ...
Performance characteristics of fiber modified hot mix asphalt
(Elsevier B.V., 2018-07-10)
A mixture of polypropylene and aramid fibers was used in this study to evaluate the performance characteristics of a modified asphalt mixture. A conventional dense-graded hot mix asphalt (HMA) used in Sao Paulo, Brazil was ...
Incorporation of synthetic macrofibres in Warm Mix Asphalt
(Lavoisier, 2018-06)
The reinforcement of asphalt concrete with fibres is not a common practice in the pavement field. Although some research papers refer to the use of microfibres, the behaviour of asphalt concrete incorporating macrofibres ...
Comparison of the n-alkanes and polycyclic aromatic hydrocarbons concentrations in the atmosphere during the preparation of warm and hot mixtures asphalt for pavements
(Sociedade Brasileira de Química, 2012)
O asfalto é utilizado na produção de misturas asfálticas a quente (HMA) para a pavimentação e, devido às altas temperaturas empregadas, gera fumos que contêm n-alcanos e hidrocarbonetos policíclicos aromáticos (HPAs). As ...
Study of Asphalt Binder’s Rheological Properties Extracted from Warm Mix Asphalts
(ASTM International, 2018-09)
The long-term performance of Warm Mix Asphalts (WMAs) is relatively unknown because this technology is fairly new. A critical question is how much the production temperature can be cut down in these mixtures without reducing ...
