Description
Technical field
The present invention relates to a kind of preparation methods of emulsifying warm-mixing agent, belong to warm-mixing agent technical field.
Background technique
Currently, the bituminous pavement in road construction is most of using traditional hot-mix asphalt mixture, for common
Hot-mix asphalt mixture, it is that matrix pitch is heated to 140 DEG C or so from room temperature, and mineral aggregate is heated to 150~180 from room temperature
DEG C, then pitch and gathering materials is mixed and stirred at a high temperature of 150~180 DEG C again, the asphalt temperature after mixing and stirring is not low
In 150 DEG C；Temperature when paving and rolling is not less than 140 DEG C.For modified asphalt mixture, modified pitch and gathers materials and heat temperature
Degree will also improve 10~20 DEG C again, and mixing and stirring temperature will also correspondingly improve.It needs to gather materials and is heated to so high temperature with pitch
Degree, mainly solves the problems, such as the workability of asphalt, and temperature is too low, and mixture will be difficult to mix and stir, pave and roll, and influences
Laying of roadway effect and service life.
In view of the factors Shortcomings such as hot-mix asphalt mixture and construction environment, Warm-Mix Bitumen Mixture is come into being.
Warm-Mix Bitumen Mixture is a kind of high energy conservation, low emission, ep-type material, mixes and stirs temperature between hot-mix asphalt mixture and cold
It mixes between asphalt.For current technology is horizontal, Warm-Mix Bitumen Mixture mix and stir temperature be generally kept in 100~
140 DEG C, paving with compacting temperature is 80~120 DEG C, and relative to hot-mix asphalt mixture, its temperature reduces 10~30 DEG C.Its mine
Expect that gradation, the mix-design of mixture, mixing apparatus etc. can correlation technique entirely by reference to hot-mix asphalt mixture and rule
It is fixed, some lesser changes need to be only done to original mixing apparatus.Make a general survey of the developing history of warm mix technology, Warm-Mix Bitumen Mixture
Advantage be mainly reflected in the following aspects:
(1) each construction link temperature is reduced, it is energy saving.Warm-Mix Bitumen Mixture can reduce by 30~50 DEG C of construction temperature, because
And the consumption of 30% or more the energy can be saved.
(2) discharge of pernicious gas and dust is reduced, environmental pollution is small, is conducive to the health of construction personnel.
(3) durability on road surface is improved.Mix and stir and roll that temperature is lower, and pitch is being applied due to Warm-Mix Bitumen Mixture
Degree of aging during work significantly reduces, to reduce the generation of early disease, extends the service life on road surface.
(4) extend construction seasons.Since the construction temperature of Warm-Mix Bitumen Mixture is lower, even if its in cold snap
Temperature loss is slow, Warm-Mix Bitumen Mixture can compacting temperature range it is wide, therefore the construction time can be made to extend to winter.
(5) tunnel construction environment is significantly improved, visibility when improving construction.
