PD 6692:2018

This standard PD 6692:2018 Asphalt. Guidance on the use of BS EN 12697 “Bituminous mixtures. Test methods” is classified in these ICS categories:

• 93.080.20 Road construction materials

This Published Document gives guidance on the use of each of the European test methods for asphalt given in BS EN 12697. The tests are divided into five groups:

1. test methods required for testing the constituent materials, as identified in BS EN 13108‑20:2016, Annex A;

2. test methods called up in at least four of the standard specifications for the different types of asphalt, BS EN 13108‑1 to BS EN 13108‑7, as identified in BS EN 13108‑20:2016, Annex B (see Table 1);

3. test methods called up in only specific standard specifications, as identified in BS EN 13108‑20:2016, Annex B;

4. test procedures used to support the test methods in BS EN 12697‑30 to BS EN 12697‑33, as identified in BS EN 13108‑20:2016, Annex C, plus BS EN 12697‑35; and

5. test methods and procedures not called up in the asphalt standards.

Where standards fit into more than one category, they are described in the first and subsequently cross-referenced. The subclauses describing each of the tests are listed in Table 1.
