33   6 ( sity of warm mix asphalt.And
based on the results of Marshall test,the paper studied the influence of compaction temperature on the
porosity,stability,flow value of warm mix asphalt mixture.And it studied the rationality of determina-
tion method of construction temperature of warm mix asphalt mixture Research shows that:based on the
equiviscous principle,it is not reasonable to use the ordinary asphalt compaction viscosity to evaluate the
warm mix asphalt compaction viscosity,and the temperature taking stability as evaluation index is low It
is reasonable to determine the construction temperature of warm mix asphalt mixture with void ratio
as evaluation index.Sasobit makes the construction temperature of 90# asphalt mixture decrease by 20
℃ and SBS asphalt mixture decrease by 23℃.3Gmakes the construction temperature of 90# asphalt
mixture decrease by 26℃ and SBS asphalt mixture decrease by 15℃.5tabs,4figs,16refs.
Key words:road engineering;warm mix asphalt mixture;construction temperature;for determi-
nation method
