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 ...
Improvements on asphalt mixtures rutting performance characterization by the use of low shear viscosity
The relationship between the rutting performance of dense asphalt concretes and the low shear viscosity (LSV) of different asphalt binders was analysed in a previous work. A LSV limit was found for the original asphalt to ...
The Pitch Lake of La Brea, Trinidad, B.W.I.
(Waterman, Trinidad, 2010-05-13)
Three men in hats linger on the pitch at the Pitch Lake, La Brea, south west Trinidad circa 1907. Numerous trees are spread across the horizon. The Pitch Lake is the largest natural deposit of asphalt in the world. It was ...
Reclaimed asphalt binder aging and its implications in the management of RAP stockpiles
Reclaimed asphalt pavement (RAP) is a granular composite geomaterial that is highly reactive to the environment under normal atmospheric conditions. The binder aging processes that contribute to pavement deterioration do ...
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 ...
Pitch Lake, Brighton, Trinidad
This is a photograph of the pitch lake, at Brighton, south west Trinidad. There is a pond on the pitch lake at left and patches of short verdant vegetation are growing on its surface. In the background there is a long ...
