Description
Technical field
The present invention relates to slag mastic rubble bituminous concrete and preparation method thereof.
Background technology
Stone mastic asphalt (being called for short SMA) is the coarse aggregate skeleton gap that a kind of bitumastic of being made up of pitch, a spot of fine aggregate, fiber stabilizer and breeze is filled gap grading, forms the asphalt of one.Present this pavement structure form can be widely used in engineering circle, mainly is because SMA has good performance at aspects such as resistance to permanent deformation, splitting resistance and weather resistance.We can say that SMA has solved in China's Road construction between the anti-rut performance of ubiquitous road surface high temperature and crack resistance at low-temperature, the contradiction between cling property and the pavement durability energy.
The coarse aggregate that is used for SMA should adopt quality hard, surface irregularity, and shape is near cubes and have the fragmentation of the crowded ability of good embedding to gather materials.Otherwise whole advantages of SMA asphalt will be difficult to show.In order to find the difference of SMA Pavement Performance under situation is gathered materials and generally gathered materials to the use high-quality, we have chosen two kinds of different coarse aggregates of diabase and limestone, prepare AC-13I type and SMA-13 type asphalt respectively and carried out the test comparison of dynamic stability, heavy traffic paving asphalt and SBS modifying asphalt have been adopted in test respectively, and comparing result as shown in Figure 1, 2.
Test shows, no matter is for SMA or any asphalt of AC type, and no matter whether asphalt modification, adopts doleritic compound dynamic stability all to be greater than to adopt limestone; For adopting limestone as the asphalt that gathers materials, no matter whether asphalt modification, the dynamic stability of SMA and AC compound does not almost have any difference, do not see the superiority of SMA type compound, and its excellent performance has just showed behind the diabase when having adopted at all.This point explanation limestone quality is not hard, can't satisfy the requirement of SMA to gathering materials, even adopted SMA type grating, but under loading action repeatedly, gathers materials and can't bring into play embedding owing to pulverized at all and squeeze effect.The explanation that this test is lively have only quality hard, surface irregularity, shape is gathered materials near cubes and the fragmentation that has good embedding to squeeze ability and just be can be used as gathering materials of SMA asphalt.
Along with the fast development of China's motorway cause, the consumption of broken building stones significantly increases, and the high-quality deficient problem of gathering materials is more and more outstanding.Because the place of production that gathers materials of production high-quality is few, just must increase the cost of material for using high-quality to gather materials, and to drop into be very large, the gather materials production capacity in the place of production of high-quality is descending at present, and the homogeneity of material will be difficult to assurance.The use properties of the express highway pavement of building in order to guarantee requires again farthest to reduce cost, and utilizing broken slag to become gathering materials of SMA asphalt has been exactly the thing that when the water comes, a channel is formed.
Slag is the byproduct that produces in the steelmaking process, good, not only wear-resisting, the grain composition shapeliness of rubble that the mechanical property of slag is more rolling, and broken slag is multi-angular, has extremely strong lock knot power.The internal friction embedding of slag is squeezed power and is better than most of natural sandstone.And good adhesivity is arranged with pitch, can prevent the expansion of slag behind the pitch parcel.Its specific heat of combustion is very big, and very suitable aggregate as bituminous concrete is used for the making on road surface.The external relatively advanced country of metallurgical industry, tackling the exploitation of slag mutually uses early, according to United Nations the investigation of the national steel slag utilization situation of the U.S. and other more than 20 industry prosperities is shown, these national slags have 50% to be used for road engineering, but China is under the situation that output of steel climbs up and up at present, the utilization ratio of slag is but very low, therefore rationally utilize slag not only can reduce pollution on the environment, the more important thing is that building materials industry enlarges the important material source that resource is developed production.At the national conditions of China, the development and use metallurgical slag has crucial meaning especially to China.
Summary of the invention
In order to improve the long-term pavement performance of bituminous concrete, alleviate the high-quality deficient problem of supply of gathering materials simultaneously, the objective of the invention is to by selecting for use slag to gather materials, develop a kind of slag mastic rubble bituminous concrete (being called for short slag SMA bituminous concrete) and preparation method thereof as road engineering.The anti-rut of this slag SMA bituminous concrete, cracking resistance and good endurance, material cost reduces greatly.
Slag mastic rubble bituminous concrete of the present invention is made up of coarse aggregate, fine aggregate, limestone dust filler, fiber stabilizer, bituminous cements.Be characterized in that particle diameter is slag greater than coarse aggregate and the particle diameter of 4.75mm less than the 4.75mm fine aggregate, it contains by coarse aggregate 60-75% (weight) in forming, fine aggregate 16%-30% (weight), 100% (weight) that limestone dust 9%-12% (weight) forms is gathered materials, the pitch that contains the weight 6-7% that gathers materials contains and gathers materials and pitch gross weight 0.2%-0.3% mineral fibre or 0.3%-0.4% lignin fibre or 0.2%-0.4% polyester fiber.
Described fiber stabilizer is a lignin fibre, mineral fibre and polymer chemistry fiber loose wadding fibrous, or in advance with pitch blended particulate state fiber.
Described bituminous cements is selected heavy traffic paving asphalt or modifying asphalt for use, and its modifying asphalt is the pitch with properties-correcting agent SBS, SBR, SIS, APP, TLA, CBR, EVA modification.
The preparation process of this slag mastic rubble bituminous concrete is as follows:
1, material is prepared
(1) slag as aggregate drying.Because slag is porous material, must guarantee before mixing and stirring that the drying property of gathering materials just is unlikely to pitch because with pitch bonded process in because the volatilization of internal moisture, and the decline with the agglutinate viscosifying power of causing gathering materials.
(2) the breeze Wingdale is levigate, keeps dry;
(3) get heavy traffic paving asphalt or modifying asphalt ready;
(4) get ready undamped loose wadding fibrous, or in advance with pitch blended particulate state fiber.
2, mix and stir material and measure material by each composition of the slag mastic rubble bituminous concrete composition of setting, pitch is heated between 160 ℃ to 165 ℃, slag as aggregate is heated between 180 ℃ to 190 ℃, and with the two mixing and stirring, add breeze again and fiber stabilizer stirs, keep the first pressing temperature to be not less than 150 ℃.
3, moulding. adopt the Marshall compaction method moulding, respectively hit 50 times slag pitch mastic macadam-aggregate mix is two-sided, three precompressed are carried out in perhaps rolling method moulding earlier, come and go then and roll 18 times.
Slag SMA bituminous concrete of the present invention belongs to a kind of of bituminous concrete, and the material composition of its slag SMA bituminous concrete and constitutional features are as shown in Figure 3.
The constructional feature of slag SMA bituminous concrete makes it possess outstanding road surface use properties.SMA type bituminous concrete, the consumption of general coarse aggregate accounts for more than 60% in the SMA mineral aggregate is formed, and has good embedding between the particles of aggregates and squeezes effect, and asphalt will have the ability of good opposing tension set; Breeze and combine fiber stabilizer, pitch has formed bitumastic and has had good cohesive action, makes asphalt possess good anti-cold cracking performance again.Because slag is a porous material, combine with bituminous and want closely common the gathering materials that compare, the asphalt asphalt membrane that forms just is not easy to peel off, and increased the cohesiveness between the material, make the internal voids rate very little (about 4%) of slag SMA bituminous concrete, seep water hardly in the road surface that forms, strong improvement the water stability of asphalt.And because porousness, the quality of slag are hard and wear resistance good, be mixed with the bituminous concrete that is rolled into after this discontinuous form grating of SMA, there is bigger hole on the surface, construction depth is big, can improve the cling property on road surface greatly, preferably resolve the contradiction of antiskid and pavement durability aspect.The inside of slag SMA asphalt is fully filled by bitumastic simultaneously, and agglutinate and air bonded possibility reduce, so the ageing-resistant performance of asphalt is good, has improved the weather resistance on road surface.
Target Mixture Ratio, production mix proportion and the production mix proportion checking three phases that designs about the hot-mix asphalt mixture proportioning in the current specifications followed in the proportioning design of slag SMA asphalt of the present invention, determines mineral aggregate gradation and best asphalt content.What slag SMA Bitumen Mix Design adopted is marshal piece volume method of design.
Because of must having mutual embedding, SMA squeezes coarse aggregate skeleton closely.Since slag particularly raw granulate fraction to have a physical and mechanical property outstanding, therefore can play good skeleton embedding and squeeze effect.Slag as aggregate after the fragmentation is by sieving the characteristics of " big centre, two is little " that can meet the SMA grating, and promptly the usage quantity of coarse aggregate and breeze is all very big, and intergrade particulate consumption is less.
Mostly asphalt content is an outstanding feature of SMA type bituminous concrete, and this is because pavement durability and asphalt content relation are very big.So SMA wishes that asphalt content has a minimum limit value.But because the usage quantity of the coarse aggregate of SMA grating and breeze is all very big, bigger asphalt content of inevitable requirement.Therefore summer SMA road surface bellding, the problem that high temperature rut and pavement structural depth diminish appears.And the use of this porous material of slag can overcome this problem.Steel slag particle surface after the fragmentation has the pore structure of a lot of macroscopic views and microcosmic, and the effect to pitch absorption can be played in these holes.If be to utilize slag as the I type or the II type dense-graded asphalt concrete that gather materials, so the result of slag adsorptive pitch will make asphalt content increase and cause cost to rise.But because SMA type asphalt itself is exactly a kind of compound of high bitumen aggregate ratio, and summer, bellding was one of its subject matter, therefore the use of slag reaches the effect that subtracts oil by effective adsorptive pitch, stops the possibility that summer, bellding phenomenon in road surface occurred.
The preferred check that needs through tests such as Marshall stability, rut, freeze thawing splittings of asphalt content, comprehensive more definite best asphalt content scope.Asphalt content has a minimum limit value, and the codes and standards that fulfil various countries differ, and this index suggestion is 5.5% in the middle of the standard of China, and the asphalt content that is lower than this index can not be used for engineering.It is 6% that the present invention selects the bituminous minimum amount.
The invention has the beneficial effects as follows, use SMA type bituminous concrete can obviously improve the long-term pavement performance of bituminous pavement, slag then can be alleviated the high-quality deficient problem of supply of gathering materials as the use of gathering materials, and can reduce the cost of engineering.The preparation technology of slag bituminous concrete is simple, is convenient to promote.
