342 Exam 1Absorption - correct answer ✔✔the ability of an aggregate to capture water or asphalt binder in surface
voids. Defined as the aggregate moisture content in the saturated surface-dry (SSD) condition
Angularity - correct answer ✔✔angular and rough-textured aggregates are usually more stable than
rounded, smooth-textured aggregates.
Flakiness - correct answer ✔✔Referred to as flat and elongated (Describes the dimensions of aggregates)
Soundness or Durability - correct answer ✔✔the ability of aggregate to withstand weathering
Toughness or Abrasion Resistance - correct answer ✔✔the ability of an aggregate to resist the damaging
effect of loads.
Aggregates exists in one of four moisture states - correct answer ✔✔- Bone dry
- Air dry
- Saturated Surface-Dry (SSD)
- Moist
Bone dry - correct answer ✔✔the aggregate contains no moisture. Achieved by drying the aggregate in
an oven
Air dry - correct answer ✔✔the aggregate has some moisture, but the saturation state is not quantified.
Saturated Surface-Dry (SSD) - correct answer ✔✔the aggregate's voids are filled with moisture but the
main surface area of the aggregate particle is dry
Moist - correct answer ✔✔the aggregate has a moisture content in excess of the SSD moisture content
, Free moisture - correct answer ✔✔the moisture content in the aggregate in excess of the moisture
content in the SSD condition
Specific-Gravity - correct answer ✔✔the mass of a material divided by the mass of an equal volume of
distilled water
Life Cycle Costs - correct answer ✔✔Deterioration and Initial costs
Deterioration - correct answer ✔✔all materials deteriorate with time and use
Initial costs - correct answer ✔✔the cost to construct the structure
life cycle costs - correct answer ✔✔the cost to maintain the structure and potentially renew the
structure in acceptable condition
composite materials - correct answer ✔✔Typically have a higher strength-to-weight ratio than
traditional materials
Typically manufactured to overcome corrosion limitation of traditional materials.
Mechanical behavior - correct answer ✔✔material response to external loads
static load - correct answer ✔✔sustained loading over a period of time. When this time frame is
extended, it is often referred to as dead load. The dead load is often the weight of the structure.
Dynamic load - correct answer ✔✔loads that generate a shock or vibration (can be periodic, random, or
transient)
Periodic - correct answer ✔✔repeats itself with time
