with verified answers
asphalt binder Ans✔✔✔-modified and unmodified asphalt cements
asphalt cement Ans✔✔✔-Dark brown or black cementitious material in which the
predominant constituents are components that occur in nature or are obtained in
petroleum processing. NOT modified
Asphaltenes Ans✔✔✔-A fraction of asphalt cement that is large in molecular size
and highly polar. When searated, dark brown solid.
Blown Asphalt Ans✔✔✔-Asphalt Cement that has been oxidized and hardened by
passing air through at an elevated temperature
Certificate of Analysis (COA) Ans✔✔✔-A document issued by the supplier of the
asphalt binder certifying that the asphalt binder meets the appropriate
specification requirements
Cross-Link Ans✔✔✔-process by which many small molecules combine to form a
single large molecule
Elastomers Ans✔✔✔-a natural or synthetic polymer having elastic properties,
e.g., rubber. Recover size and shape after removal of a deforming force
Fractional distillation Ans✔✔✔-process of separating a volatile liquid into
fractions based on its boiling point
, HMAC Ans✔✔✔-Hot-Mix Asphalt Concrete
Long Crude Ans✔✔✔-The residue from atmospheric distillation. (whats left after
the first fractional distillation
Morphology Ans✔✔✔-Implying the molecular structure of an asphalt binder
oils Ans✔✔✔-A very fluid( low viscosity ) somtimes colorless fraction of asphalt
cement that is non-polar
Plastomers Ans✔✔✔-asphalt cement modifiers that are plastic-like. typically solid
at room temp and melt when added to asphalt cement at mixing temperatures.
Resins Ans✔✔✔-the largest fraction of an asphalt cement, when separated dark
in color highly viscous and polar
Short Crude Ans✔✔✔-Residue from a vacuum distillation
Compression Ans✔✔✔-implies compressing, pushing, or shortening. occurs when
load is applied parallel to the direction of displacement
Consistency Ans✔✔✔-the resistance of a material to deformation (strain) caused
by the application of force( stresses)
Creep Compliance (Pa^-1) Ans✔✔✔-Ration formed by dividing the strain at a
specified time by the corresponding stress. ( inverse of stiffness)
