What
is UHPC Phalt?
UHPC Phalt is a grouted macadam comprising
an open graded asphalt that is flooded with high
strength microsilica based mortars. The open
graded asphalt is mixed to a design mix at a
local asphalt plant and delivered to site in tipper
trucks. It is placed via traditional paving techniques.

The
UHPC Phalt mortars are delivered in
1 tonne bags and mixed via a continuous flow
pump machine. The mortar is mixed for a certain
amount of time to achieve correct viscosity then
flooded via a large hose onto the asphalt matrix.

UHPC Phalt can be laid at depths of 30 mm /
1,18 in upwards (typically maximum depth used
is 40 mm / 1,57 in). UHPC Phalt is the top layer
of the pavement that is supported by a basecourse
layer. The basecourse layer can vary dependent
on environment and loadings, internal or external
applications. Preferred basecourse materials to
support the UHPC Phalt topping are high modulus
macadam basecourse or Foamix recycled
binder
course. CBM bases are ideal for use for large
internal areas.
The UHPC Phalt pavement structure (DPH +
Basecourse) is laid onto varying depths of Type 1 stone/capping dependent on the CBR value of
the sub-grade.
