1 Scope
This document describes three test methods for characterizing the compactability of a bituminous mix,
by the relation between its density or void content and the compaction energy applied to it, using an
impact (Marshall) compactor, gyratory compactor, or a vibratory compactor.
This document applies to bituminous mixtures, both those prepared in laboratory and those resulting
sampled from plant produced mixtures. The results of the test method serve to supplement the results of
mixture design.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

3.1
compactability
K, k
ability of an asphalt mixture to be compacted (K when evaluated by gyratory compaction and k when
evaluated by vibratory compaction)
Note 1 to entry: High values of K and k will indicate a mixture for which less compaction energy is required to
obtain a given void content decrease.
3.2
compaction resistance
C, T
resistance of an asphalt mixture to being compacted (C when evaluated by impact compaction of several
specimens with varied compaction energy and T when evaluated by impact compaction of one specimen
while measuring its thickness)
Note 1 to entry: High values of C and T will indicate a mixture for which high compaction energy is required to
obtain a given void content decrease.
4 Principle
The bituminous mixture is compacted at a prescribed temperature with varying compaction energies
using one of three optional types of compaction methods:
a) impact compaction
b) gyratory compaction
c) vibratory compaction.
Two methods of monitoring the compactability can be applied:
— Method 1: two or more specimen are compacted with different amounts of compaction energy and
their densities are measured.
— Method 2: one specimen is used and its increase in density during the compaction process is
determined from its decrease in thickness.
The following Table 1 defines the compaction type to use depending of the compactness of tracking
method and gives the clause of test procedure.
Table 1 — Compaction type
Procedure clause according to
compaction method
impact gyratory vibratory
Compaction of specimens with carried compaction energy 6.1.1 n. a. 6.3
Measurement of specimen thickness during compaction 6.1.2 6.2 n. a.
A graph is drawn of density (or voids content) against compaction energy. When the impact compaction
is used, the compaction energy is characterized by the number of blows, when the gyratory compaction
is used, by the number of gyrations and when the vibratory compactor is used, by the duration in seconds.
A mathematical formula is derived from the experimental results, the parameters of which formula
characterize the compactability of the bituminous mixture.
