More details Abstract: The collaborative project was funded by
Highways England, Mineral Products Associations and
Eurobitume UK and was specifically aimed for
reviewing bitumen based surfacing materials,
drawing upon international experience, with the view
to developing new asphalt surfacing materials which
offer enhancement to durability, whilst balancing
other performance demands such as noise and
safety. AECOM led the project delivery team and
completed a successful international workshop and
construction of demonstration trials on two sets of
the next generation asphalt surfacing materials.
These materials comprised modification to Clause
943 polymer modified hot rolled asphalt and a
bespoke performance based polymer modified
Premium Asphalt Surfacing System (PASS). The mix
design principle for these materials is based on a low
voided, dense body, durable asphalt material with
improved surface characteristics (low noise and good
macrotexture). During the laboratory and field
assessments, the test results were benchmarked
against those expected for Clause 942 thin surface
course systems. This presentation details the mix
design, construction and road trials experience,
including recommendations for the implementation
of these materials on the Strategic Road Network in
England.
