Recommended application rates for RS-1 and CRS-1 tack coats

vary, but are typically between:

• 0.01-0.05 liters/m^2
• 0.05-0.10 liters/m^2

or F - ---Answers---True

A leveling course (also known as truing and leveling) may be appropriate when the pavement cross section has deformed

due to failing mixture:T or F - ---Answers---False

Milling typically removes most surface cracks 3-3.5 inches

deep caused by aging and surface stressed: T or F - ---

Answers---False

The rate at which HMA mixture is delivered to the jobsite should be balanced with the paving crew's ability to place and

compact the mixture within the specified requirements: T or F

• ---Answers---True

If no blue smoke is rising from a load of HMA it is an indication

that the plant is not heating the material sufficiently: T or F - --

-Answers---False

Tarps are required on all haul units: T or F - ---Answers---

True

It is acceptable if HMA to not be uniform if it is smooth and

dense: T or F - ---Answers---False

segregation by remixing the material from the haul unit: T or F

• ---Answers---True

Best practice is to maintain the level of material in the paver hopper so that the hopper drag slats are visible between

loads: T or F - ---Answers---False

common cause for joints to open up: T or F - ---Answers---

True

• / 4

Prior to paving the screed should be set to a null position and

the angle of attack should be induced: T or F - ---Answers---

True

When hot material is placed against the first mat, an overlap between 1"-1.5" of fresh mixture onto the cold mat is used to

ensure adequate material for compaction at the edge: T or F -

---Answers---True

If there is excessive material at the joint, the loot operator

should broadcast material across the mat: T or F - ---

Answers---False

The pull of the paver, the head of material, the angle and mass of the screed are the main factors in determining how the

screed reacts to a smooth and uniform riding surface: T or F -

---Answers---True

Longitudinal joint densities are on average between 1-6%

higher than the density of the mat: T or F - ---Answers---

False

Ultimately, it seems the method of the joint constructed is more responsible for quality joints than the experience and
