Surfix C
Surfix C is a conventional grade cationic
bitumen emulsion for surface dressing.
By using selected emulsifying agents with a
suitable emulsion grade penetration bitumen
it has been specifically designed for use as a
hot applied surface dressing binder.
Being an emulsion of bitumen in water, Surfix C,
when compared with the traditional anhydrous
binders has the following advantages:
• It is applied at the lower, therefore safer
temperature range of 80º to 90ºC
• There is a negligible fire risk and the hazards
of fuming are minimal
• The wetting and adhesion to chippings and
road surfaces is excellent
• It is more tolerant to dusty chippings and
lightly coated chippings are never required
or indeed recommended
• The higher residual viscosity in the early life
of the dressing provides a greater resistance
to traffic stresses
• The stabilised dressing is less prone to
flushing up in hot weather conditions
• It is more ‘user-friendly’
Surfix C is loaded into clean road tankers at or
near the spraying temperature. Care must be

taken during subsequent heating to ensure that
the binder is thoroughly circulated and that the
temperature does not exceed 90ºC. Above this
temperature there is a danger of severe frothing
which may result in spillage and possible noncompliance
with the specification.
Application
Surfix C should be applied at the correct rate of
spread to the road surface by calibrated spray
tankers to conform to BS1707 (Hot Binder
Distributors for Surface Dressing).
The surface dressing works should be in
accordance with the recommendations
contained in Road Note 39 and the Road Surface
Dressing Associations Code of Practice and
Guidance Notes. As a guide, rates of spread are
generally in agreement with Road Note 39,
Chippings must be uncoated, of good quality,
dust free and conforming to BS EN13043.’
Standards
Surfix C complies with BS EN 13808:2005 for
C69B3 or C69BF3 (formerly K1-70 to BS 434 - 1).
