Mixing of hot-mix colored asphalt concrete
, hot-mix The mixing methods and technical requirements of colored asphalt concrete are basically the same as those of ordinary asphalt concrete.
Before producing colored asphalt concrete, the mixing tank should be cleaned, and the cement transportation pipeline should be set up separately to prevent the original black asphalt from being contaminated.
In order not to affect the use quality of R bright asphalt, before construction and mixing, the storage temperature should be controlled at ℃ when the storage days are less than 3 days, and the storage temperature should be controlled at ℃ or normal temperature when the storage days are greater than days. When cooling and hardening to normal temperature and reheating with a burner, in order to prevent the cement from being locally heated, please use interval heating until half of the stored cement is dissolved. (For example: heating up every hour, extinguishing fire every hour).
The construction temperature of colored asphalt binder should be determined by measuring the viscosity temperature curve under the conditions of &℃ and &℃. In the absence of viscosity-temperature curve data, you can refer to the following ranges for selection: RⅠ colored asphalt binder heating temperature &~℃, & stone heating temperature &~℃, mixing temperature ~℃, discharging temperature &~℃, paving temperature not lower than ℃, the initial pressing temperature is ~ ℃, and the final rolling temperature should not be lower than ℃. The heating temperature of R colored asphalt binder is &~℃, the stone heating temperature is &~℃, the mixing temperature is ~℃, the discharging temperature is &~℃, the paving temperature is not lower than ℃, the initial pressing temperature is ~℃, and the final rolling temperature is not below ℃.
In order to make the pigment evenly distributed, the mixing time should be reasonably determined. The mixing time is generally longer than that of ordinary asphalt concrete.
Strictly control the mixing temperature and mixing time. The difference in mixing temperature of each plate of materials is less than ℃, and the difference in mixing time is less than.
2. Construction of cold-mix colored asphalt
Cold-mix colored asphalt is also called cold-paved colored asphalt and cold-patched colored asphalt. This kind of cold-mix colored asphalt pavement can be constructed without heating. Cold-mix colored asphalt The price is much more expensive than hot-mixed colored asphalt, and the construction of this material relies entirely on labor, so the construction cost is relatively expensive. The selling point of cold patching is that it is easy to operate and does not require as large a machinery as hot patching. It also has relatively loose requirements on the environment, traffic control and surface treatment. First, draw a cordon to enclose the area that needs to be repaired, then clean the road surface to remove all foreign debris (soil, gravel, sand, etc.), sweep it with a broom, and then use a hair dryer to blow away the dust, sand, etc. and dry the road surface thoroughly. Then spray the colored asphalt mixture
&. After cleaning, according to the owner's requirements, if you want to retain the original markings, use tape of a specific size to protect the markings, arrows, text, etc. In order to protect the curb stones For cleaning, greening and pollution-free, etc., it is necessary to use a baffle to cover the edge of the spray boom to prevent pollution caused by mist-like fine materials splashed under strong pressure.
&. Use an artificially adjustable speed motor and a stirring blade to stir each barrel of asphalt emulsion, stir it evenly, and then add emery at a constant speed. According to different road conditions, the proportion of sand can range from a minimum of no sand to a maximum of % emery (put a paper cup at room temperature, no more than one pound at most). After adding, set the mixing speed to the fastest setting and keep stirring at high speed for minutes. , let the mixture be mixed thoroughly, and let the asphalt emulsion fully coat every grain of silica sand
&. There are two methods of construction:
& direct spraying by machine (put curing agent), (recommended for heavy traffic),
&Manual pushing and scraping method (put curing agent and emery), (recommended for light traffic such as sidewalks, bicycle lanes, etc.)
&Machine direct spraying: add the mixture at room temperature Go to the container of the spraying equipment, flow through the pipe into the spray gun, and spray directly and evenly.
&. After spraying or scraping, be sure to remove the tape quickly to avoid sticking to the road surface
&. Hours after the construction is completed After that, it can be opened to traffic
Three: Colored permeable concrete construction technology
Generally, the standard is used as the benchmark thickness of the sidewalk. On this basis, different thicknesses are designed according to different functions. To reduce costs, layered design can be used. When constructing the above-mentioned single-layer or layered permeable concrete pavement, the key construction technology is the guarantee of the quality of the permeable concrete pavement. Biaomei Colorful Stone provides the following construction plans.
. Preparation before construction: Three major preparations, including organization, material and technology, should be made before construction.
.Organizational preparation: Establish a sound construction project organization structure and staffing structure, based on the principle of being able to achieve the tasks required by the construction project. Staffing must be strictly controlled, and strive to have one person with multiple functions and one person with multiple positions.
B. Material preparation: The construction of permeable concrete is essentially similar to the construction of cement concrete. The raw materials only lack sand, and high-quality gravel of a certain particle size replaces the aggregate. There is a certain amount of materials in the construction ( cementing material, high material).
Material preparation should be on-site preparation, such as accommodation of personnel, required water and electricity supply, sheds for stacking engineering materials (work sheds that require waterproofing measures for cementing materials), setting up sites for mixing machinery, etc. Preparation.
In the installation site of the mixing machinery, a small horizontal mixer is used for mixing permeable concrete. The best installation plan for the mixer is in the middle section of the construction site. Since permeable concrete is dry material and its initial setting is fast, the transportation time should be as short as possible to ensure that the transportation time is as short as possible. In order to prevent concrete from sticking to the construction site, a certain range of the lower part of the mixer needs to be fortified with protective boards.
. Construction machinery, carts, bricklaying tools and other necessary tools, wood or steel for molding, etc. are equipped with water and electricity facilities in place, including domestic water and electricity as well as construction water and electricity. Construction electricity: three-phase electricity, construction water: ordinary tap water connected to the mixing equipment.
D. Technical preparation before construction: Understand and analyze the characteristics and progress requirements of the project, understand the objective conditions of the construction, familiarize yourself with the design drawings according to the design requirements, rationally arrange the construction forces, and formulate a construction plan to ensure the smooth completion of the project. Make technical preparations.
. Cooperate with the civil engineering team doing the foundation work to lay the special permeable pipes while building the ground base. In addition to being laid according to the requirements of the drawing, the permeable pipes must be connected to the original road drainage system and become an integral part of the road drainage system. part.
.Construction: Only on the basis of sufficient preparations, personnel and equipment can enter the site for construction.
. Formwork erection:
Constructors must first carry out separate and regional formwork erection work according to design requirements. During formwork erection, attention must be paid to issues such as height, verticality, flooding slope, etc.
B. Mixing:
Mixer: According to the size of the project, mechanical mixers with different capacities are configured. The ground within a certain range of the mechanical mixer should be equipped with a material catcher to prevent water and materials from scattering. Equipment (such as square plate buckets) can protect the hygiene of the construction environment and reduce the cleaning work after construction.
Permeable concrete cannot be mixed manually, and ordinary concrete mixing machinery is used for mixing. When mixing, the materials are put into the mixer according to the specified proportion and feeding order of the materials. The cementing material and gravel are first stirred for about a second, and then they are initially mixed. , then add the specified amount of water one at a time and continue stirring for about 1 minute. Depending on the uniformity of the mixing, the mechanical mixing time can be appropriately extended, but it is not advisable to mix for too long.
Notes:
A dedicated person must be responsible for the proportion of materials at the construction site.
Strictly control the water-cement ratio, that is, control the amount of water added. Water is added in batches during stirring, and is not allowed to be added at one time.
In order to stir the materials evenly, the mechanical stirring time should be appropriately extended, but not too long.
.Transportation
Permeable concrete is a dry concrete material, and its initial setting is fast. The transportation time of the mixture is generally controlled according to climatic conditions. Transportation is generally controlled within minutes. Do not stop during transportation, and the trolley must be stable.
D. Paving and pouring:
Permeable concrete is a dry concrete material with fast initial setting, so it must be paved in time. For sidewalks, large-area construction uses the method of paving materials in blocks and silos, and its loose paving coefficient is. Spread the mixture evenly on the work surface, use a ruler to check the flatness and control a certain degree of flooding, and then use a flat vibrator (use a flat vibrator if the thickness is thick) or manually tamp. High-frequency vibrators should not be used for tamping. Finally, smooth it out with smoothing. There should be no exposed water when applying.
Notes:
The loose paving coefficient is the ratio of the material paving height to the actual height. According to the dry humidity of permeable concrete, it is generally between.
The vibration time of the flat vibrator should not be too long to prevent it from being too dense and causing segregation.
When paving, try to be quick and correct.
Because permeable concrete has large porosity and loses water quickly, when the temperature is higher than ℃, the construction time should be avoided at noon, and it is suitable to carry out construction in the morning and evening.
. Health care:
Permeable concrete has similar properties to cement concrete, so after paving, it is inspected that the elevation and flatness meet the requirements. When the temperature is high, in order to reduce the evaporation of water, it is advisable to cover it immediately with plastic film to retain moisture. Spraying water can also be used for health care, and all health care periods should not be less than d, so that the strength gradually increases during the curing period.
Sprinkling and curing: watering and curing of permeable concrete begins the day after pouring. When the temperature is high, curing begins after an hour. However, it is not advisable to use pressure water to directly shower the concrete surface when pouring water. Water should be sprayed directly from top to bottom. The wet curing time of permeable concrete should not be less than 3 days.
The curing time should be determined according to the construction temperature. Generally, the curing period is days. When the temperature is high, it should not be less than days. When the temperature is low, the curing period should be no less than days. For construction below ℃, the curing period should be no less than days.
. Apply transparent sealer:
After the surface concrete is molded and dry, apply a transparent sealer in about a day to enhance durability and aesthetics. Prevent the pores of permeable concrete from being contaminated and blocked over time
