Description
Technical field
The present invention relates to pavement construction material technical fields, more particularly to a kind of acidity aggregate asphalt that is used for be modified
Reinforcing agent and application.
Background technique
The common building stone of asphalt concrete pavement has caustic lime rock and partial neutral basalt, these materials because its with
Pitch has preferable adhesiveness and is widely used.Since the very fast development speed of the finiteness and highway of natural resources makes
The high-quality situation for having reached that supply falls short of demand of gathering materials largely used is obtained, brings great pressure to the exploitation and supply gathered materials,
Basalt and limestone become more and more in short supply as the ideal coarse aggregate of bituminous concrete.However, acidity aggregate and pitch
Adhesiveness does not often reach requirement, using under the corrosion function of water, making through alternate load after the pavement forming of acidity aggregate
Pitch and mineral aggregate are detached from, until loosely falling grain, pit slot occur, lead to pavement destruction, and then influence communications and transportation.
Summary of the invention
The present invention provides a kind of reinforcing agents and application modified for acidity aggregate asphalt, solve existing skill
The problem of art.
Used technical solution is the present invention to solve above-mentioned technical problem:
A kind of reinforcing agent modified for acidity aggregate asphalt, including the modifier A and modifying agent being used cooperatively
B；The quality of modifier A is the 0.2%-2% of acidity aggregate asphalt mesostroma asphalt quality, and the quality of modifying agent B is
The 0.4%-1% of acidity aggregate asphalt gross mass；
The modifier A is silane coupling agent；Modifying agent B is bitumen solid powder.
The partial size of the modifying agent B bitumen solid powder is 300-600 mesh.
The silane coupling agent is KH550 or KH570.
The bitumen is the bitumen of asphaltenes and glial component.
Application of the reinforcing agent modified for acidity aggregate asphalt in acidity aggregate asphalt,
Including following operating procedure:
(1) it according to acidity aggregate asphalt total amount to be prepared and prepares acidity aggregate matrix used for asphalt mixture and drips
Green quality, determines the quality of modifier A and modifying agent B；Prepare matrix pitch, acidity aggregate, miberal powder, modifier A and modification
Agent B, it is spare；
(2) matrix pitch is heated to 140-160 DEG C, then the modifier A of step (1) is added in matrix pitch and is mixed
Time 20-60min is closed, modified pitch is obtained；
(3) modified pitch of step (2) is added in acidity aggregate by 160-200 DEG C of computer heating control acidity aggregate temperature,
Mix 90s obtains product 1；
(4) modifying agent B is added to together with miberal powder in the product 1 that step (3) obtains, in 150-170 DEG C of mix 90s,
Up to the molding acidity aggregate asphalt that can pave at 120-150 DEG C.
Beneficial effects of the present invention:
The reinforcing agent modified for acidity aggregate asphalt is relative to other common modifying agent, bulk composition
For bitumen, cost is more advantageous；It is asphalitine and glial component that bitumen, which selects 300-600 mesh, ingredient, with base
Matter bitumen compatibility is good, low to the quality requirement of matrix pitch；Wet-process modified pitch can effectively be avoided using dry mixed
Generally existing isolation, the problems such as stability is poor.
The asphalt modified compared to rock asphalt, mineral etc., the present invention using silane coupling agent to matrix pitch into
Row is modified, then mix acidity aggregate and modified pitch, then by bitumen and above-mentioned material mix by the way of dry method, this
Sample can fully play bitumen and the respective performance advantage of coupling agent, and forming properties are complementary, solve acidity aggregate not
The problem of asphalt aggregate can be used as.Silane coupling agent can make the acidity aggregates such as pitch and granite with chemical bond phase
Even, contain Si-OH in the asphalt component specially after admixture silane coupling agent, there are HO-Si, the two combination shapes for granite face
At Si-O-Si chemical bond；Contain a large amount of asphalitine component in bitumen, the high-temperature behavior of pitch can be improved.
The mix temperature of currently used asphalt reinforcing agent is higher, increases the cost of fuel consumption；Except this it
Outside, heat ageing reaction, the discharge of toxic gas and exhaust gas of pitch result in environmental pollution.This is used for the mixing of acidity aggregate pitch
Modified reinforcing agent is expected when being applied to laying of roadway, and mix temperature and forming temperature are reduced compared with ordinary hot mix asphalt
It tens degree, saves energy consumption, the effective degree of aging for weakening pitch, while the reduction of mix temperature can reduce poison gas
The discharge of body reduces the harm to human and environment to the greatest extent, has ideal social benefit, economic benefit and Environmental Effect
Benefit.
