Marshall Stability Test Procedure
Marshal test is extensively used in routine test programs for the paving jobs The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C The flow is measured as the deformation in units of 025 mm between no load and maximum load carried by the specimen during stability test (flow value may also be...

A survey of soils for aggregate stability ,
Aggregate stability was linearly correlated (p < 0001) with all measures of glomalin (mg/g of aggregates) in these soils The best predictor of aggregate stability (AS) was immunoreactive easily extractable glomalin (IREEG) according to the following relationship: AS = 427 +613 × log 10 IREEG (r 2 = 086; p...
