2.03 BEDDING AND JOINT SAND
Note: If pavement will be exposed to heavy traffic with trucks i.e. a major thoroughfare with greater than 1.5 million 80 kN equivalent single axle loads, contact ICPI for test method and criteria for assessing the durability of bedding sand.
A. Provide bedding and joint sand as follows:
a. Washed, clean, non-plastic, free from deleterious or foreign matter, symmetrically shaped, natural or manufactured from crushed rock.
b. Do not use limestone screenings, stone dust, or sand for the bedding sand that does not conform to the grading requirements of [CSA A23.1] [ASTM C33].
c. Do not use mason sand or sand conforming to [CSA A179] [ASTM C144] for the bedding sand.
d. When concrete pavers are subject to vehicular traffic, the sands shall be as hard as practically available.
e. Sieve according to [CSA-A23.2] [ASTM C 136].
f. Bedding Sand Material Requirements: Conform to the grading requirements of [CSA A23.1-FA1] [ASTM C33] with modifications in Table 1 below:

Note: Coarser sand than that specified in Table 2 below may be used for joint sand including [CSA A23.1] [ASTM C33] material as shown in Table 1. Use material where the largest sieve size easily enters the smallest joints. For example, if the smallest paver joints are 2 mm (1/16”) wide, use sand 2 mm (1/16”) and smaller particle size. If bedding sand is used for joint sand, extra effort may be required in sweeping material and compacting the pavers in order to completely fill the joints.
B. Joint Sand Material Requirements: Conform to the grading requirements of [CSA A179] [ASTM C144] as shown with modifications in Table 2 below:
