3.1.0 Shoulder Construction
3.1.1 Description
3.1.2 Materials
This work shall consist of constructing shoulders on either side of the
pavement, in accordance with the requirements of this specification and in
conformity with the lines, grades and cross-sections shown on the drawings
or as directed by the Engineer.
Shoulder may be of selected earth or grannlar material conforming to the
requirements of embankment construction or granular sub-base construction
respectively.
3.1.3 Construction Operations
3.2.0 Kerb
3.2.1 Material
Except in the case of bituminous constructions, shoulders shall be
constructed in advance of the laying of pavement courses. The compacted
thickness of each layer of shoulder shall correspond to the compacted layer
of pavement course to be laid adjacent to it. After compaction, the inside
edges of shoulders shall be trimmed vertical and included area cleaned of all
spilled material before proceeding with the construction of the pavement
layer.
In the case of bituminous courses, shouldering operations shall start only
after the pavement course has been laid and compacted.
Regardless of the method of laying, all shoulder construction material
shall be placed directly on the shoulder. Any spilled material dragged on to
the pavement surface shall be immediately removed, without damage to the
pavement and the area so affected thoroughly cleaned.
During all stages of shoulder construction, the required cross-fall shall be
maintained to drain off surface water.
Kerb, if required for construction of footpath, shall consist of precast
concrete blocks with a concrete grade of M-15. The blocks shall be 100 mm
wide and of suitable length. The depth of blocks unless otherwise mentioned
elsewhere, shall be 375 mm considering 225 mm height of footpath from the
road level.
