Description
[technical field]
The invention belongs to technical field of road engineering materials, relate to a kind of asphalt and preparation method thereof.
[background technology]
Reform and opening-up is over 30 years, highway in China development is rapid, as the infrastructural industries of national economy, the development of highway construction to Accelerating The Construction united market, realize effective distribution of resources, promote the coordinated development of all regions, improve open degree, promote the national economic development and social progress to play important function.After the peak period of highway construction, substantial amounts of highway will be faced with reconstruction and maintenance, at this moment will produce substantial amounts of old asphalt mixture, environment and soil will be caused the biggest pollution by these old asphalt mixtures, how to utilize these old asphalt mixtures of recovery will become one and study a question.
Waste asphalt mixture simply functionally decreases, and Colophonium is the most aging, and performance of gathering materials can also utilize.Therefore, by the recovery to waste asphalt mixture, adding suitable new Colophonium and newly gathering materials, heating uniform mixing can be made new asphalt completely and be applied to pavement structure.So solve waste asphalt mixture and pollute environment, it is also possible to save substantial amounts of building stones and petroleum resources, building stones, Colophonium resource reuse the meaning sent out during the sustainable development to China has very.
Regeneration mainly mixes the method such as hot recycling, cold in-plant recycling in bituminous paving original place hot recycling, bituminous paving original place cold renewal, length.These methods have weak point to a certain extent and there is shortcoming, cold recycled asphalt mixture is compared with heated tool butt-welding asphalt, the quality of heated tool butt-welding asphalt is compared can be more preferably, but the aggregate heating temperature of heated tool butt-welding asphalt is all higher than common hot-mix asphalt mixture with mixing and stirring temperature, and therefore power consumption is big.Due to temperature height during mixing and stirring, Colophonium is the most aging, very big at work progress medium pitch cigarette, affects the health of workmen.In the today paying attention to energy-conserving and environment-protective, need to find a kind of better method to solve this problem.
Along with China GDP maintains sustained and rapid growth, total energy consumption persistently rises, and the discharge of China's greenhouse gases is paid close attention to by countries in the world, reduces the discharge of harmful gas to be the task of top priority, for China, the application of research and extension WMA technology has highly important realistic meaning.In conjunction with current situation both domestic and external and the specific requirement of engineering, and the practical situation of China, the shortcoming fundamentally changing heated tool butt-welding asphalt in the past, play warm-mixed recycled asphalt mixture energy-saving and emission-reduction and the effect of safety and environmental protection, accelerate to digest and assimilate research promotion WMA technology, there is significant economic benefit and social benefit.
[summary of the invention]
In order to realize the purpose of regeneration asphalt warm mix and solve the problem that reclaimed asphalt mixture hot asphalt is the most aging, the invention provides a kind of warm-mixed recycled asphalt mixture and preparation method thereof, what this warm-mixed recycled asphalt mixture reduced regeneration asphalt conscientiously mixes and stirs temperature, adopts the following technical scheme that for this present invention
A kind of warm-mixed recycled asphalt mixture, including: old asphalt mixture, Colophonium, newly gather materials, breeze, regenerative agent and warm-mixing agent；Warm-mixing agent be moisture content be 18%-23% inorganic silicon-aluminum hydrochlorate；It is in terms of 1 part by Colophonium parts by weight, old asphalt mixture 3-8 part, 5-28 part of newly gathering materials, breeze 0.3-1 part, regenerative agent 0.006-0.05 part, warm-mixing agent 0.06-0.12 part.
The addition of above-mentioned warm-mixing agent is the 0.3% of warm-mixed recycled asphalt mixture weight, and the 25% of above-mentioned breeze weight is slaked lime.
Meanwhile, present invention also offers the preparation method of a kind of warm-mixed recycled asphalt mixture, comprise the following steps:
A, old asphalt mixture and newly gathering materials is heated to 140-150 DEG C dry after join and mix and stir in pot, pre-mix 80-100s, mix and stir kettle temperature and be maintained at 140-150 DEG C；
B, Colophonium is heated to 145-155 DEG C after join and mix and stir in pot, regenerative agent and warm-mixing agent are sprinkling upon the surface of Colophonium, in mix pot, mix and stir 80-110s；
C, breeze is joined and mixes and stirs in pot, mix and stir 80-100s, obtain warm-mixed recycled asphalt mixture；
D, this warm-mixed recycled asphalt mixture is taken the dish out of the pot at 135-145 DEG C, at 130-140 DEG C of compacted under.
In above-mentioned steps c, the mixing time of breeze is 90s.
Warm-mixing agent selected by the present invention be a kind of moisture content be 18%-23% inorganic silicon-aluminum hydrochlorate, profile is white powder, warm-mixing agent is added during reclaimed asphalt mixture mixes and stirs, extend 15～30 seconds duration of mixings, thus in binder, produce foaming, this is due to the moisture in warm-mixing agent at about 100 DEG C with superfine state sustained release out, it is allowed to foam with asphalt grouting, reduce asphalt viscosity, make the Colophonium can be uniform with aggregate blending under relatively low temperature conditions, foamable reaction in liquid phase binder plays the effect of lubricant, play warm mix effect, the temperature of mixing and stirring making compound significantly reduces to 135～145 DEG C.
Warm-mixed recycled asphalt mixture of the present invention has the advantage that 1) reuse waste asphalt and building stones；2) add conveniently, it is not necessary to additionally increase equipment；3) applied widely, it is possible to for the compound of various gradation types；4) the aging of work progress medium pitch can be reduced；5) service life of bituminous mixture blending equipment is extended；6) warm-mixing agent used uses natural minerals to do raw material, does not results in environmental pollution；7) construction temperature at least can reduce by 30 DEG C with the construction temperature of grating hot asphalt relatively；8) consumption of fuel can be reduced, about can save the energy of 30% compared with HMA: 9) reduce CO2、SOx、NOx, VOC, the discharge of the harmful substances such as dust, thus reduce the destruction to environment and the health hazard to workmen；10) can more stably store the longer time, it is simple to storage characteristics produces, extend transportation range.
