02


Chloride Content

Specifies the determination of the chloride content in aggregates which can have a negative binding effect in some construction applications.

03


Water Soluble Salt Content

This standard specifies a method for determining the total water-soluble salt content of fine aggregates and of fines in aggregates for base courses.

04


Deleterious Clay Content

This method determines whether the clay content of the fines of an aggregate contains deleterious swelling or active clay minerals.

05


Initial Stabilizer Content

Determines the percentage of stabilizer that will first be absorbed by material to neutralize acidity levels before stabilizing takes effect.

Category Image

06


Moisture in Asphalt

Used to determine the percentage moisture in a freshly mixed hot mix asphalt (HMA) mix.

Category Image

07


Plasticity index Hydrometer test

To determine the particle size distribution of materials to detail the silt and clay percentages.

Category Image

08


Rock Durability Using 10% FACT

Used to determine the strength of the aggregate sample after it has been exposed to a weathering agent.

Category Image

09


Back-titration

To determine the percentage of stabilizer added during the construction phase to assess design and proper mixing.

Category Image

10


Particle & Relative Density

The ratio of mass to the mass of an equal volume of water, which defines the weight or density of a material.

Category Image

11


Methylene Blue

Determines whether the clay content of the fines of an aggregate contains deleterious swelling clay minerals which could adversely affect the quality of the asphalt mix.
