Probabilistic assessment of asphalt pavement design
In Chile, as in many South American countries, AASHTO-93 is the current official method for the design of asphalt pavements. The method gives an estimated number of 80 kN standard axle loads (W18) that the pavement can ...
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 ...
Ageing and performance of warm mix asphalt pavements
(Elsevier B.V., 2017-08-01)
This paper presents results from investigating the ageing behaviour and performance of different warm mix asphalt (WMA) pavement mixtures also called energy reduced pavements. The mixtures were either prepared in the ...
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 ...
Adherence in a pavement rehabilitated with a polymeric grid used as interlayer
A polymeric grid was placed between layers of a pavement with the aim of preventing the reflection of cracks from the base material to the upper layer. Results explain why the usual faults that occur in rehabilitated ...
Wheel tracking rutting performance estimation based on bitumen Low Shear Viscosity (LSV), loading and temperature conditions
The development of new technologies and road pavement materials require the evaluation of the asphalt mixture performance. Rutting is one of the main modes of failure of asphalt mixtures; it is typically studied at the ...
