| Conventional
wisdom has it that your choice is limited to just
two types of products when it comes to repurposing
asphalt millings or treating recycled pavement materials
during full depth reclamation (FDR) of failed pavements.
You can either treat the material with an asphalt
emulsion-based product, which produces relatively
small gains in strength and stiffness at considerable
expense, or you can cement the material together with
cement at the risk of constructing a rigid layer with
cracking problems. The other conventional option is
to use both categories of these two products in combination,
which further increases the cost. Fortunately, there
is a more cost-effective way to repurpose asphalt
millings as well as mixtures of pulverized asphalt
and concrete and recycled base into strongly bound
materials with pavement-like behavior. With over three
decades of field performance on record, the economical
EMC SQUARED System Stabilizer product has proven effective
as a sole treatment for recycled materials. As illustrated
by the graphs below summarizing the test results of
a study in a pavement materials testing laboratory,
the application of the EMC SQUARED Stabilizer treatment
resulted in a bound asphalt millings material that
had far higher density and strength than the same
asphalt millings materials treated with asphalt emulsion.
