Roller-Compacted Concrete Pavement

Quiz Questions

1. RCC mixtures have "positive" slump.
2. Which of the following components typically are considered to develop a mixture with the greatest density and strength at the lowest cement content?
Water content
Sand content
Aggregate size
All the above
3. A variety of subbase types can be used under an RCC pavement structure, but due to the tightness of the transverse cracks in RCC, it is not always necessary to use a stabilized base layer.
4. Vertical Cold joint, Angular Cold Joint, Fresh Joint are examples of _______________?
Traverse joint
Longitudinal joint
Cross joint
None of the above
5. The continuous-type horizontal shaft mixer provides a higher range in production rates up to 500 cy/hr, with most around__________.
100 cy/hr
200 cy/hr
500 cy/hr
1000 cy/hr
6. The batch-type horizontal shaft mixer can yield production rates up to approximately ___________ while providing excellent mixing efficiency for dry materials.
100 to 140 cy/hour
150 to 180 cy/hour
210 to 260 cy/hour
260 to 320 cy/hour
7. RCC is placed without forms, reinforcing steel, or surface finishing.
8. Which of the following are the most important benefit of RCC?
Cost effectiveness
Ease of Construction
Long lasting
All the above
9. RCC mixtures have suffered only minor spalling distress under freeze/thaw action and typically are not susceptible to freeze/thaw damage. Therefore, air entrainment typically is not required in RCC mixtures.
10. RCC pavement has been used in which of the following applications?
Military installations
Minor arterials
Highway frontage roads and shoulders
All the above
