Abstract

A semi-rigid asphalt concrete that can be produced under ambient temperature by applying traditional cement concrete production method. A high temperature heating and great pressure rolling that are necessary for producing asphalt concrete in conventional skills are never being constraints while producing the semi-rigid asphalt concrete. The method of producing the semi-rigid asphalt concrete generates less air pollution than the traditional method for producing hot mix asphalt concrete. The semi-rigid asphalt concrete consists of cationic emulsified asphalt, type-I cement, F-type superplasticizer, Na-Carboxymethyl Cellulose (Na-CMC), calcium chloride (CaCl2), stone dust, and IIId, IVb, or VII a gradation aggregates. By applying the procedure of producing cement concrete, the semi-rigid asphalt concrete is completely produced after mixing, placing, and curing. The cationic emulsified asphalt and the F-type superplasticizer are first mixed to generate a mixture, and then pour the prepared CaCl2 and Na-CMC solution for continuous mixing. After the mixture is mixing evenly, the cement, stone dust, fine aggregate, and coarse aggregate are sequentially pouring to the mixture for mixing. While the mixture is mixed evenly, the mixture is placing and curing, and it can be used after harden enough.

Description of the Invention (5-1 Field of the Invention The present invention relates to a kind of semi-rigid asphalt concrete, which is based on the technology of interfacial chemical adjustment and is assisted by the concept of emulsion stability. 'Using cationic emulsified asphalt, Typej Cement, F_Type superplasticizer, slow methylcellulose steel, gasification, stone powder, and sand and gravel grades ⅠΠ d, IV b, and wa grades are used as raw materials, and the materials are mixed according to the method of cement concrete manufacturing It is formed by combination, placement and curing, which completely changes the traditional asphalt concrete that must be manufactured using high-temperature mixing and sub-compacting manufacturing methods and hot mix construction methods. ----------. ¥- zi. \ (Please read the precautions on the back before filling this page) In addition, the semi-rigid asphalt concrete disclosed by the present invention is not only easy to mix and construct, but also can replace the traditional asphalt concrete hot mix method, and can also reduce the pollution of exhaust gas. It can also use the existing cement concrete mixing plant equipment 'and rigid pavement construction machinery for material manufacturing and construction. Because semi-rigid asphalt concrete has the characteristics of factory manufacture or on-site mixing, pouring, and compaction-free, the construction is less restricted by terrain and landforms, and it is not affected by weather during construction. In addition, in general road pavement, road, Parking semi-rigid asphalt concrete pavement, improvement of grass-roots soil site improvement, waterproof waterproof step-by-step floor, labor-resistant non-slip layer 'sports flooring, repair of flooring, etc.' It can be regarded as a very practical and commercial invention ^ Tu 5-2 Background of the invention: The paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) η 5. Description of the invention () (Please read the notes on the back before filling this page.) In the process of economic development, the country ’s economic development often leads to an increase in animal traffic and wheel load as the industry develops, and the load on road paving also increases. In the past, in the construction of pavement projects, the asphalt concrete surface was made of hot-greenish concrete, and the asphalt concrete was compacted by gravity to achieve the desired design strength. The green paving surface laid in this way is called flexible paving. 'Flexible paving has better flexibility' and can get a more comfortable driving feeling. However, due to the inherent limitation of the material, the hot-sampling paving surface is prone to rutting deformation, cracks, and surface slippage due to the weight of the wheel, which can damage the paving structure. Later, because cement concrete was used for road paving, this cement mixed soil paving is called rigid paving, and the mechanical damage of the road paving was reduced. However, due to the high strength and rigidity of cement concrete, vehicles running on rigid paving have greater bumps, poor driving comfort, higher engineering costs, and difficult construction techniques required. Moreover, the maintenance of paving is not easy, so it becomes The drawback of using cement concrete for paving. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints traditional hot-mixed asphalt concrete with occasional addition of cement, but most of them are used as a filler. 'Cement has no cementation function in asphalt concrete, and the maximum amount of addition is about 1 〇 ~ 丨 5%, there is no significant increase in the mechanical strength of asphalt concrete after the addition of cement. B. National Central University Institute of Civil Engineering's master's thesis test in the Republic of China in 77, used cement with a weight ratio of 0.5 to 2%. As an additive for emulsified asphalt concrete, it was found in the test results that as the amount of cement added increased, the asphalt concrete's encapsulation decreased, its stability increased, and its fluidity increased. 5 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 40B089 5. Description of the invention () (Please read the precautions on the back before filling this page) It can be seen that 'if cement is used as emulsified asphalt Although the filling material of concrete can increase a little stability value or strength, but for the asphalt concrete as a whole, the addition of cement as a filler will make the filling effect of the fine particles in the asphalt concrete, which will be reduced due to the hydration of the cement with water. The ground increases its porosity and reduces its ability to resist water erosion and pavement displacement. Therefore, there is still a need to improve asphalt concrete. 5-3 Purpose and summary of the invention: In view of the above-mentioned background of the invention, "there are some problems with traditional flexible paving and rigid paving materials", the present invention proposes improvements for its disadvantages. Special treatment, and developed a flexible paving material that can be used at room temperature and has high strength, and named this paving material Semi-Rigid Asphalt Concrete. Another object of the present invention is to disclose a method for manufacturing and construction of materials that can use existing cement concrete mixing and corrosion: equipment, and rigid pavement construction machinery.

The liquid immediately reduced to asphalt cement and water. Because of the discovery of this key mechanism, the treated emulsified asphalt suspension can be uniformly mixed with cement and granules by external force 'to produce semi-rigid asphalt concrete of good quality. Furthermore, 'the higher the degree of dehydration of the cement asphalt mortar, the higher the viscosity of the cement, so that the aggregate can be controlled so that it does not segregate, so that the viscosity of the semi-rigid asphalt concrete will not hinder it during mixing. It is also a breakthrough obtained by the present invention in the A mixing technology. σ Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The second picture describes the process of finding a better material ratio for the semi-rigid asphalt concrete of the present invention. After all the materials are prepared (step 201), the cationic emulsified asphalt and F_Type are first controlled. The proportion of the plasticizer is poured into a stirring device for mixing (step 202). After the mixing is uniform, the calcium gas and Na-CMC solution prepared in advance are mixed (step 203). After mixing well, pour the cement and stone powder (step 204) to form a cement asphalt mortar. The ratio of cationic emulsified asphalt to cement can be determined according to the fluidity of the cement asphalt mortar and the compressive strength requirements of the hard solid specimen. After mixing, add the grading fine particles (step 206), and refer to the Marshall ratio design method to make an asphalt mortar sample to find out the content range of the fine particles (step 205).

The fourth figure describes the preferred embodiment of the present invention Flow chart of the manufacturing process of semi-rigid asphalt light condensate. First, the mixed solution of cationic emulsified asphalt and F_Type strong plasticizer must be uniformly distributed (step 41). If some milky products are generated during the stirring process, it must be continued. Perform the mixing operation until the milky substance disappears (step 42) ', and then pour in the pre-prepared calcium carbonate Na-CMC solution, and then let the mixing equipment continue the mixing (step 43). The calcium chloride M-CMC solution is obtained by dissolving calcium chloride in a Na-CMC solution with a concentration of i%, and then mixing them evenly. After mixing, add Type-I cement and stone powder to make the mixture. The equipment continues the mixing action (step 44). After mixing, add the fine granules and continue mixing (step 45). Finally, pour the coarse granules and stir (step 46). Wait until the mixture is uniform and then discharge the material for pouring.

Description of the invention () The soil still retains about 90% of its compressive strength after severe environmental erosion '. However, the thermal concrete asphalt is below 75% . In terms of stability, the amount of rutting deformation in the fifth figure can also be used. According to the fifth figure, under the condition of a temperature of 60 ° C and a pressure of 19.4 kg / cm2, the rut deformation of the hot-mixed asphalt concrete at the age of 7 days is about 7.25 legs; but the semi-rigid under the same conditions Asphalt concrete md, IVb, and Wa gradation are only 0.43im, 1.12 coffee! , And 1. 3 6 fine rut deformation. It can be seen that the stability of semi-rigid asphalt concrete is indeed higher than that of hot-mix concrete. The sixth chart uses the slump test data to compare the workability of semi-rigid asphalt concrete and cement concrete. Due to the use of rigid pavement construction equipment for semi-rigid asphalt concrete, the slump must be controlled at 10 cm or less. If compared with the slump of 3 ~ 8cm required for the construction of the North Second High Rigid Pavement in Taiwan, it can be seen that the semi-rigid asphalt concrete of the present invention has better workability than the cement concrete of the rigid pavement. And because the semi-rigid asphalt concrete can cause retardation of cement after adding Na-CMC, the initial setting time of semi-rigid asphalt concrete may be slightly longer than that of cement concrete, about 3.5 to 4 hours, so the material during construction The transport distance has greater flexibility, and its slump loss is also small. Therefore, semi-rigid asphalt concrete is more convenient than hot-mixed asphalt concrete and cement concrete in terms of workability. The seventh picture is a comparison of the strength of semi-rigid asphalt concrete and cement concrete, and hot-mixed concrete. Semi-rigid asphalt concrete can bear the load due to the addition of cement to the material 'solids produced by cement hydration 14 This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 public love) ---_--- .------- 1 '^ -------- tT.iT.1 ----- Green.

Description of the Invention () In addition to 'can also increase the effect of bonding with sand and gravel. As can be seen from the seventh figure, the strength of semi-rigid asphalt concrete is about 2 to 3 times higher than that of hot-mixed asphalt concrete, but the elastic modulus is only about 20% higher. Therefore, semi-rigid asphalt concrete has a capacity to bear traffic loads. And, it has pavement material which is similar to asphalt concrete. In addition, 'the test results from the heating box aging, freeze-thaw cycle aging, and dry-wet cycle aging' showed that the temperature, humidity, moisture, and heat energy of the environment, and the proportion of winter damage to the interface between the binder and the sand and gravel in the semi-rigid asphalt concrete. It is not high because the semi-rigid asphalt concrete is a high-strength and flexible multi-mortar concrete, and its water tightness is higher than that of hot-mixed asphalt concrete, so it has high financial and long-term characteristics. Furthermore, 'the properties of freshly mixed semi-rigid asphalt concrete are similar to that of cement concrete, and the maintenance and strength generation methods after construction are similar to that of cement concrete'. The strength needs to be generated by hydration of cement, which is similar to heat loss. ^ Concrete The method of generating strength by compaction and cooling is completely different. Therefore, semi-rigid asphalt concrete can be manufactured and manufactured using cement concrete mixing plant equipment in manufacturing and construction, and automated mechanical construction using rigid pavements.
