This British Standard specifies requirements for the transport, laying
and compaction of those asphalt mixtures conforming to
BS EN 13108-1, BS EN 13108-4 and BS EN 13108-5, described in
PD 6691, from the time that they leave the mixing plant until they are
placed on the road ready to receive a superimposed layer or traffic. It
also includes requirements for preliminary work at the laying site
needed to ensure that the substrate is fit to receive the asphalt and for
the application of tack coats and bond coats.
While this standard does not include explicit requirements for asphalt
materials covered in other parts of BS EN 13108 or other proprietary
asphalt mixtures, the general requirements of this standard may be
applied to those mixtures, in addition to special requirements for
particular mixtures as laid down in individual quality plans and/or
method statements.
NOTE 1 The term “asphalt” used in this standard is the generic term used
to describe the wide range of mixtures of aggregate and bituminous
binder individually known as asphalt concrete, coated macadam, hot
rolled asphalt, stone mastic asphalt (SMA), porous asphalt or mastic
asphalt and other proprietary materials which are available for use in
constructing and maintaining roads and other paved areas that are on
the market in the UK.
Protocols for the initial type testing of asphalt materials in accordance
with BS EN 13108-20 Type testing are included in Annex C, Annex D,
Annex E, Annex F and Annex G.
NOTE 2 BS EN 13108-20 Type testing details the way in which the
conformity of a mix composition to the requirements of the specification is
to be determined. This is similar to a mix design validation or job mix
trial. BS EN 13108-20 offers some choice in the way in which specimens
are to be prepared for the purposes of initial type testing. Since the results
determined will depend on the method of specimen preparation, a set of
protocols showing the recommended UK selection of such procedures,
linked to the recommended specification levels and classes, is included in
this standard.
In the case of hot rolled asphalt (HRA), requirements are specified
for providing a rough-textured surface on the surface course for
skid-resistance.
This standard does not include requirements for asphalt incorporating
bitumen emulsion binders.
