Additional Tolerances

» The deviation from a 3m long straight edge placed anywhere on the surface of the base layer shall
not exceed 25mm for subbase and 15mm for base layer.

Transverse to the centre line and between any two points more than 2m apart, the crossfall shall not
depart from the crossfall shown in the documents by more than 0.5% absolute.

4.1.3 Final Trim

Following placement and compaction of the base course material, the whole of the surface of the base
course shall be final graded and trimmed to the specified tolerances so as to leave a hard, dense, tightly
packed surface free of lenses, compaction planes and caking.

Asphaltic concrete surfacing shall not be commenced until the profile, surface, compaction, quality and
finish of the pavement have been inspected and confirmed satisfactory.

4.1.4 Quality Control Testing

The cost of all testing of materials to ensure quality control during construction shall be borne by the
Contractor. If processed samples are unsatisfactory, cost of additional necessary testing will also be
bome by the Contractor.

The Contractor shall comply with the Quality Assurance requirements as specified herein.
» Pavement Quality Tests as follows:

~ Gradings, Atterbergs and Soaked CBRs (for each pavement course, 1 test for each 400m of
material);

- Tests to determine properties in accordance with Local Council specification (for each pavement
course 1 test for each source of material supplied).

» Pavement Compaction Tests:

— Test each pavement course layer at the rate of 1 test per 1,000m? with a minimum of three (3)
tests per sample area.

» Pavement Geometric Tolerances:

— Primary Level (along centreline at every chainage cross section given in plans or every 25m,
whichever is lesser of the two);

— Straight Edge Deviation (left and right hand side at every chainage cross section given in plans or
every 25m, whichever is the lesser of the two).

- Crossfall (ss above).
4.2 Subsoil Drains
