Asphalt Compactors
Typical Application Description
(relative to work application)
Low
Asphalt mix, 25-50 mm
(1-2 inch)
lifts. Static finish rolling, all lifts.
Medium Asphalt mix, 51-100 mm
(2-4 inch)
lifts.
High
Asphalt mix, 101-150 mm
(4-6 inch)
lifts. Prepare granular base lifts.
Vibratory Soil Compactors
Typical Application Description
(relative to work application)
Low
Granular soil not compacted to high density (<95 Proctor). Residential street work with lift
thicknesses up to 150 mm
(6 inch)
working the initial compaction. Level ground, minimal
slopes and intermittent periods of waiting for base work completion or material delivery.
Speeds in the middle of the low range (2-3 km/h
[1-2 mph]
). Minimal start and stop of the
vibe function.
Medium Granular soil compacted to density (>95 Proctor). Cohesive soils with padded drum and low/
normal moisture content, blading <25%. Continuous operation on thicker lifts 150-350 mm
(6-14 inch)
or doing the final passes on stiffer materials or working at the top end of the low
speed range. Working on slopes greater than 5% or rapid directional changes combined
with start and stop of the vibe function.
High
Cohesive soil with padded drum and high moisture content. Combined high load factors
from the medium duty application. Working on thick lifts greater than 350 mm
(14 inch)
,
slopes greater than 15%, or applications requiring significant blade work. An example
would be trench work with backfilling.
