CONCRETE ROADS
Kerbs.—In Northbrook Street the kerbs (of concrete) were
laid in situ with |-in. joints, as in the case of the footways them-
selves.
the original footpaths were being retained, an outer form
only was required for the kerb. This was placed in position on
the road slab and about four or five inches from the edge, so that
the outer portion of the kerb rests upon the roadway itself.
Before placing the concrete for the kerb, a strip of tarred paper
was laid in the bottom of the trench formed by the edge of the
pavement and the outer form. This strip, which may be seen
Fig. 8.—Concrete road in Northbrook Street, Newbury. The kerb
is here seen under construction. In the foreground the strip of
tarred paper will be observed lying in the bottom of the trench.
The form is kept in position by spacers on the inside and blocks of
stone on the outside.
in Fig. 8, covered over the 2-in. space which has been mentioned
above and which acts as a longitudinal joint to the roadway.
The concrete was then placed in position up to the level of the
footpath, and finished off with a steel trowel. The appearance
of the finished kerb is very neat.
Cost.—The total cost cannot, at the time of going to press,
be given exactly, but is expected to work out at approximately
£1 2s. 6d. per super, yard. As prices rule to-day this is not high,
and in the present instance is regarded as eminently satisfactory.
