Bitucrete is a deferred set, storage macadam which has been
approved by the BBA for use as a first time permanent repair
material in footways; footpaths and cycle tracks (certificate
07/H128). It is also ideal for instant high quality temporary
repairs. Bitucrete is cold applied and therefore safe to
Available in a variety of grades, Bitucrete can be used for
footway repairs, patching, reinstatements and temporary
Bitucrete provides an immediate cure for potholes in car parks,
roads, drives, factory floors and many other surfaces.
Bitucrete is a combination of penetration grade bitumens,
additives and selected aggregates. High PSV granite or basalt
aggregate makes it suitable for all classes of road and footway.
Available in black and red.
Where to use?
- Fills worn areas in paths and drives
- Patches potholes in bituminous surfaces
- Reinstates trenches in lightly trafficked surfaces
- Provides temporary ramping off for high kerbs and exposed
ironwork Bitucrete has a storage life of up to six months in sealed
bags and under good storage conditions. Bags are batch numbered for
easy stock rotation.
Ensure that the surface to be repaired is clean and free from
loose material, oil, grease and standing water. Prime base surface
with Colas Leotak tack coat. Edges of the area to be repaired
should be formed vertically as far as possible and then treated
with Colas Bitukold or RS Bitukold edge sealant prior to forming
joints. For small potholes, Bitukold or RS Bitukold may be used
over the surface area of the hole as a tack coat. Workability can
be ensured even in cold weather by simply manipulating the
Bitucrete in its sealed bag.
N.B: To aid workability of bagged Bitucrete in winter, store
bags in a warm area (>10°C ambient temperature) for 24 hours
prior to use if possible.
Tip sufficient Bitucrete from the bag to over-fill the hole,
ensuring that all corners are filled. Compact the material to the
surrounding level using a compactor, roller or hand tamper
depending on the nature of the site. For large areas use a
vibrating plate or roller slightly wetting the drum with water. If
under-filling has taken place, simply add more product and compact
to level. Material should not be laid any deeper than 2½ times the
size of the nominal stone in any one layer. The repair will
withstand immediate heavy trafficking. However, where the repair is
to be crossed by fork-lift trucks and HGVs, extra compaction and
curing time must be allowed. Bitucrete remains flexible for some
time after application. As the material will take up the contours
of potholes naturally and form an immediate repair, it is ideal for
irregularly shaped potholes. Curing is brought about by both air
drying and compaction. The rate of cure is dependent upon
temperature as well as the weight and volume of traffic. However,
under normal traffic conditions, Bitucrete will not depress, track
or pick up during the curing process.
Spread Rate Guide
The table shows the approximate rate of spread of various
compacted thicknesses of Bitucrete. Please note that the covering
capacity of Bitucrete may be affected by such factors as the
density and grading of the aggregates, condition of the substrate
and final state of compaction. On more irregular substrates,
heavier rates of spread are to be expected.
