Updating Bituminous Stabilized Materials Guidelines Mix Design Report Phase II

Taking into account the stated TSR ranking criteria, and comparing these results with ravelling
depths from MMLS3 tests as well as previous triaxial analysis which provided Retained Cohesion
ratios, provides the comparisons in Figure 25. This highlights the empirical nature of the TSR in
measuring moisture related resistance of BSMs, as it is inconsistent with the other results.
Reasonable comparison is obtained from MMLS3 tests and triaxial tests in terms of moisture
sensitivity of BSMs. However, only limited results are available at present although more
research is in progress.
