Transcribed Image Text:Fill the blanks in the following statements about HMA construction.
a) In a paver the
receives HMA from the conveyor
and spreads it out evenly over the width to be paved. The paver provide
compaction between
and
percent of maximum density.
b) In cold weather paving the
Available for
compaction is limited because HMA
rates increases.
c) As a rule of thumb the depth of the compacted lift should be at least
the maximum aggregate size of
the nominal maximum aggregate size.

Transcribed Image Text:d) For compaction of thick lift (beyond 2.5 in) vibratory compactors
settings should be set at
frequency and
amplitude
