All forms of highway need regular maintenance to keep them in optimal condition.
SPE Contracting have a wealth of experience in this area and can offer exceptional
service when it comes to surface preparation projects involving all forms of highways
- including pedestrian walkways...
Some of the more common processes undertaken by SPE Contracting are provided below.
Surface re-texturing using captive shot blasting techniques is
a process where small steel shot is propelled at speed onto the asphalt surface,
removing deeply embedded surface contaminants, dirt and grit. This dust free,
environmentally friendly process restores the asphalt surface texture
without damaging the surface structure with speed and efficiency.
Line markings on asphalt surfaces can be similarly removed using
the captive blasting technique, preserving the integrety of the underlying asphalt
surface structure.
Cleaning & removal of surface contaminants is a common task
on concrete surfaces and is primarily achieved using dust free, environmentally
friendly captive shot blasting techniques. A keyed surface also results for the
application of thick coatings if required. Captive shot blasting is also the method
of choice for removing laitance on newly laid concrete surfaces,
and also the removal of line markings.
Anti skid / anti slip surface removal is necessary when performance
has degraded and the anti skid surface is to be renewed or removed altogether. Because
of the nature of such surfaces, surface planing is often the technique of choice,
allowing for the removal of the surface to a greater depth whilst also leaving a
keyed surface ready for the new surface coating.
Surface levelling / removal of high spots on concrete surfaces
can be achieved using surface planing techniques. This can often be quicker and
more cost effective than using more complex levelling compounds. In cases where
significant depths of concrete need to be removed, cold planing (or milling) becomes
the surface preparation technique of choice, leaving a keyed surface with anti-skid
properties that can be used as a temporary highway.
Asphalt & concrete removal to much greater depths is often
required when a complete, new flexible / asphalt surface is to be reapplied on roads
and highways. Cold Planing (or Milling) is the primary method of
choice in such tasks, eliminating the need for complex levelling courses whilst
leaving a highly skid resistant surface that can be used by traffic until the new
surface can be applied.
