Addition of fibers to the mix in SMA pavements is done to control drain down.

Define complete street design and name two features of such design.

Jointed reinforced concrete pavements (JRCP) typically have longer slabs (larger spacing between joints) than jointed plain concrete pavements (JPCP).

Explain the Urban Heat Island phenomenon.

Recycling is an activity that can have favorable impacts on pavement sustainability. Name 2 impacts.

Porous Friction Courses (PFCs) consist of very coarse “open” gradation, in which materials passing certain sieve sizes are missing. The aggregates should be durable, rough textured, and resistant to abrasion and polish.

Recycled asphalt pavement (RAP) is the 5th largest recycled material in tons in the United States.

The three pillars of sustainability are: social equity (people), environment (planet), and economy (profit).

Keeping in mind what you know about the concept of sustainability in general, if you were appointed to a high federal level position overseeing tribal communities, how would you close the social equity gap? Be creative.

In jointed plain concrete pavement (JPCP), no slab reinforcement is used except for dowel bars placed at transverse joints or tie bars at longitudinal joints.
