plant. Plant type and environmental controls all have an effect on the HMA properties and may produce HMA with different characteristics than those designed in the lab. For these reasons, specimens are prepared by the Technician from plant produced HMA to verify proper density, air voids and VMA from the original laboratory design.
A small asphalt plant producing 100 thousand tons of asphalt a year may release up to 50 tons of toxic fugitive emissions into the air. [Dr. R. Nadkarni] Stagnant air and local weather patterns often increase the level of exposure to local communities. In fact, most asphalt plants are not even tested for toxic emissions.

The modification by polymers and nanomaterials can significantly improve different properties of asphalt. However, during the service life, the oxidation affects the constituents of modified asphalt and subsequently results in deviation from the desired properties. One of the important properties affected due to oxidation is the adhesive properties of modified asphalt. In this study, the ...
