The purpose of this research was to assess the feasibility of constructing highperformance paving (Superpave) for Kazakhstan with only locally sourced ingredients.
Similarly, a standard Marshall technique combination that meets the technical requirements
of Kazakhstan was compared. One granite aggregate supplier, 2 aggregate grading,
and 2 types of asphalt binder made up the test design. Consensus and source aggregate
characteristics requirements met with the Superpave design mix method using locally
manufactured granite aggregate. Also, the mixtures volumetric parameters indicated that
the asphalt binder content of the superpave combination has shown lower than locallytraditionally Marshall mix. The combinations of Superpave fared better in rutting and
moisture resistance tests than those made in the conventional manner. After the ITS values
from both samples were averaged, the decrease in significance for the superpave mixtures
was 9.1%. It was below the 20% loss level required by the Superpave guidelines. Also
by rutting resistance results were significantly differences for 85.5% PG70 with 9.5mm
NMAS. All of these results point to the superiority of new method Superpave over the
Marshall method.
