Abstract
The Cause of Pavement Failure in Tropical
countries like Nigeria and the factors responsible
for best-performance asphaltic concrete surfacing
are reviewed. Consequently appropriate laboratory
tests consisting of both Marshall and Indirect
tensile tests were conducted in order to determine
the desirable optimum binder content, which maximises
all the desirable properties of good-performance
asphaltic concrete. To evaluate the effects of each
factor, it's influence on the following performance
parameters of asphaltic concrete were measured and
monitored:- Marshall stability and stiffness,
Indirect tensile strength and compressive modulus
of the specimens and compacted density of the mix.
The factors considered and varied to appropriate
levels for this study included the:- Testing
temperature, compactive effort, binder content;
and Aggregate gradation; shape and surface texture.
It was found out that testing temperature which
simulatet
the ambient temperature have an adverse
effect on the performance of asphaltic concrete.
It was also found out that for Nigerian type of
climate and traffic loading a high binder content
of optimum value of 7% and stone content of Optimum
range of (50-6590 are needed for best performance
asphaltic concrete
