Abstract
The invention discloses an asphalt mixture mineral powder. The asphalt mixture mineral powder is prepared from the following raw materials in parts by weight: oil shale, limestone and an additive. Oil shale serves as mineral powder of an asphalt mixture for the first time, the binding force and the strength of mucilage formed between mineral powder and asphalt, as well as between mineral powder and the additive, the interspace of asphalt concrete is reduced, and relatively high dispersibility is realized. Key indexes such as the high-temperature rut resistance, the low-temperature cracking resistance and the water encroachment resistance of the asphalt mixture are improved, and the probability of 'looseness' of a traditional asphalt pavement is effectively reduced. Waste of oil shale resources is reduced, and the transport cost is lowered. The asphalt mixture mineral powder provided by the invention is simple in process, low in cost, high in performance and environment-friendly, and the invention also provides a production method of the asphalt mixture mineral powder.
Description
Technical field
The invention belongs to Chemical Engineering Technology, resource circulation utilization and road and bridge construction field, be specifically related to a kind of asphalt breeze and preparation method and resinous shale and preparing the application in asphalt breeze.
Background technology
Because China has been in the rapid economic development phase, road engineering there occurs earth-shaking change, and bituminous pavement even spreads into country lanes.In some atrocious weather area, especially the northern area of China, due to round the clock and Seasonal Temperature Difference huge, pitch shrinks repeatedly, result in traditional asphalt road surface " loose ".The key solving road surface " loose " is the composition of asphalt.The three-dimensional scatter system that asphalt is made up of coarse aggregate, fine aggregate and rubber cement, the rubber cement wherein comprising breeze and pitch is then the key factor determining asphalt high and low temperature performance, more and more comes into one's own in recent years.Breeze is normally obtained through levigate processing by alkaline building stones such as limestone, and what in asphalt, play filler effect take calcium carbonate as the mineral powders of main component.Breeze plays filling effect in asphalt, and object is the space reducing bituminous concrete.Breeze and pitch form asphalt mastic jointly, improve the strength and stability of bituminous concrete.So, require between breeze and pitch, there is stronger avidity.At present, the demand of traditional breeze is increasing, and cost increases gradually.Finding a kind of type material replaces traditional breeze just to seem particularly urgent and important.
China's oil shale reserves is huge, can prepare shale oil through high temperature carbonization method.But dry distillation can only extract the shale oil of about 70%, residue more than 20% heavy shale oil backfills with oil shale residues, causes resource and manpower waste, has certain environmental pollution simultaneously.Resinous shale and dry rectificating oil shale waste residue become to be grouped into kerogen and mink cell focus primarily of the inorganic oxide such as silico-aluminate and Ca, Mg, K.The resinous shale (<6 mm) that particularly some granularities are little is unwell to distillation process, causes ample resources to waste.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of asphalt breeze is provided, solve the bonding force of rubber cement in prior art and the relatively low problem of intensity, and provide cost savings.
Another object of the present invention is to provide a kind of preparation method of asphalt breeze and resinous shale preparing the application in asphalt breeze.
Technical scheme of the present invention is as follows:
Asphalt breeze, is prepared from by following raw materials in parts by weight number ratio, resinous shale: Wingdale: additive=20-50:20-60:2-20.
Oil shale residues after described resinous shale comprises resinous shale raw ore, distillation process and be unwell to the resinous shale small-particle of distillation process.
Described resinous shale meets China's industry standard: " standard specification for construction and acceptance of highway asphalt pavement " JTG F40-2004 relevant regulations.
Described resinous shale pulverizes and sieves to granularity and is less than 0.60 mm.
Described Wingdale meets China's industry standard: " standard specification for construction and acceptance of highway asphalt pavement " JTG F40-2004 relevant regulations.
Described Wingdale pulverizing is screened to granularity and is less than 0.60 mm.
Described additive is one or several in diatomite and hydrophober.
The preparation method preparing this asphalt breeze comprises the steps: resinous shale, Wingdale to be carried out pulverizing and being screened to targeted particle size by above-mentioned ratio of weight and number; Mix with additive again and carry out the configuration of uniform stirring for road oil rubber cement.
Advantageous effect of the present invention is as follows:
The inventive method is in traditional asphalt mixture process, first using the breeze of resinous shale as asphalt.The asphalt breeze prepared of the method is adopted to utilize the organic compositions such as the bituminous matter of resinous shale periphery, mink cell focus and kerogen, mixed and hydrophobic principle by similar, significantly improve the bonding force and the intensity that form rubber cement between breeze and pitch and additive, reduce the space of bituminous concrete simultaneously, there is higher dispersiveness.Improve the key indexs such as the high temperature Rut resistance of asphalt, low temperature cracking resistance and water resistant infringement, effectively reduce traditional asphalt road surface " loose " situation.Described asphalt breeze can be used for, in the construction of all bituminous coat projects, having compatibility to all pitch.
The inventive method adopts oil shale powder to decrease the waste of oil shale resources as asphalt breeze, especially in northern China part shale oil producing region, remains oil shale residues after a large amount of destructive distillation, can gather materials on the spot, decrease transportation cost.The invention provides that a kind of technique is simple, cost is low, the breeze of the asphalt of high-performance and environmental protection and production method.
Resinous shale and through the composition and property of distillation process oil shale residues due to self, has suitable hardness, is applicable to carrying out by pulverizer the solid granule being ground into target order number, and has good mobility, can freely flow out from mineral powder bin.Meanwhile, the composition burning-points such as the kerogen adhered to around resinous shale and heavy oil are high, can increase rubber cement and other bonding forces of gathering materials simultaneously, have higher hydrophobic nature.So this small-particle is particularly suitable for being used as the breeze in asphalt.
