Abstract: in recent years, along with the economy of the
total amount of ascension, highway in China for goods
transportation with a huge help, however, because design
construction personnel comprehensive quality is low, or the
highway
by
dynamic
load
vehicle
larger,
at
present
our
country
many highway appeared different degree of damage. Through the
analysis of copper yellow freeway roadbed packing CBR test,
granule analysis test, liquid plastic limit experiment test
results, the study soil particle composition, mineral
composition
and
content
of
factors
such
as
subgrade
filling
CBR
value
influence,
and
put
forward
the
effective
improvement
and
optimization measures to improve the strength of the highway
subgrade and carrying capacity, ensure highway the overall
quality and safety has the important practical significance.
Keywords:
highways;
