瀝青水泥撒布車施工路面怎么做?使用透水混凝土的施工步驟有那幾點?為了瀝青水泥撒布車施工路面的使用效果發(fā)揮大的作用，下面是詳細的介紹：

How to construct the pavement with asphalt cement spreader? What are the construction steps of using permeable concrete? In order to play a big role in the application effect of asphalt cement spreader, the following is a detailed introduction:

瀝青水泥撒布車施工路面就是把高標(biāo)號水泥（材料:粉狀水硬性無機膠凝材料)，6mm粒徑大小的小米石加上一些添加劑，按照一定比例攪拌攤鋪而成的。

Asphalt cement spreader construction road surface is made of high-grade cement (material: powdery hydraulic inorganic cementitious material), 6 mm grain size of millet stone and some additives, mixed and spread according to a certain proportion.

瀝青撒布車施工路面詳細施工步驟主要有五步：

The detailed construction steps of asphalt spreader are as follows:

攪拌：透水混凝土拌合物中水泥（材料:粉狀水硬性無機膠凝材料)漿的稠度較大，且數(shù)量較少，為了便水泥漿能保證均勻（jūn yún)地包裹在骨科上，宜采用強制式攪拌機，攪拌時間為5分鐘以上。彩色防滑路面是一種嶄新的路面美化技術(shù)，可讓傳統(tǒng)的黑色瀝青混凝土和灰色水泥混凝土的路面，通過彩化施工達到路面色彩賞心悅目，同時具有防滑效果

Mixing: the consistency of cement slurry (material: powdery hydraulic inorganic cementitious material) in pervious concrete mixture is relatively large, and the quantity is relatively small. In order to ensure that the cement slurry can be evenly wrapped in orthopedics, the forced mixer should be used, and the mixing time is more than 5 minutes. Color anti-skid pavement is a brand-new pavement beautification technology, which can make the traditional black asphalt concrete and gray cement concrete pavement, through the color construction, achieve the road color pleasing to the eye, and have anti-skid effect at the same time

澆筑：在澆筑之前，路基必須先用水濕潤。否則透水混凝土快速失水份會減弱骨料間的粘結(jié)強度。由于透水混凝土拌合物比較干硬，將拌和好的透水混凝土和好的透水混凝土材料鋪在路基上鋪平即可。

Pouring: before pouring, the subgrade must be moistened with water. Otherwise, the rapid water loss of pervious concrete will weaken the bond strength between aggregates. As the permeable concrete mixture is relatively dry and hard, the mixed permeable concrete and good permeable concrete materials can be paved on the subgrade.
              

振搗：在澆注過程中不宜強烈振搗或夯(hāng)實。一般用平板振動器(操作方式:氣動閥)輕振鋪平后的透水性混凝土混合料，但必須注意不能使用高頻振搗器，否則他會使混凝土過于密實面減少孔隙率，并影響透水效果。同時高頻振搗器也會使水泥（材料:粉狀水硬性無機膠凝材料)漿體從粗骨料表面離析出來，流入底部形成一個不透水層，使材料失去透水性。

It is not suitable to vibrate strongly during pouring. Generally, flat plate vibrator (operation mode: pneumatic valve) is used to gently vibrate the paved permeable concrete mixture, but attention must be paid not to use high-frequency vibrator, otherwise it will make the concrete too dense, reduce the porosity, and affect the permeable effect. At the same time, the high-frequency vibrator will also make the cement slurry (material: powdery hydraulic inorganic cementitious material) separate from the surface of coarse aggregate and flow into the bottom to form an impermeable layer, which makes the material lose its water permeability.

輥（gǔn)壓：振搗以后，應(yīng)進一步采用實心鋼管或輕型壓路機壓實壓平透水混凝土拌合料，考慮到拌合料的稠度和周圍溫度等條件，可能需要多次輥壓，但應(yīng)注意，在輥壓前必須清理輥子，以防粘結(jié)骨料。彩色防滑路面防滑涂料按施工方式分為熱熔型和冷涂型兩類；按抗滑性高低，分為普通防滑型、中防滑型、高防滑型三類。冷涂型按干燥速度分為快干型和慢干型。高摩擦系數(shù)的彩色防滑路面，有效地提高行車安全。

Roller (g ǔ n) compaction: after vibration, the permeable concrete mixture shall be further compacted and leveled by solid steel pipe or light roller. Considering the consistency of mixture and surrounding temperature, it may need to be rolled for many times, but it should be noted that the roller must be cleaned before rolling to prevent aggregate bonding. According to the construction method, the colored anti-skid coating for anti-skid pavement can be divided into two types: hot melt type and cold coating type; according to the anti-skid performance, it can be divided into three types: ordinary anti-skid type, medium anti-skid type and high anti-skid type. According to the drying rate, the cold coating type can be divided into quick drying type and slow drying type. The colored anti-skid pavement with high friction coefficient can effectively improve the driving safety.

瀝青水泥撒布車施工路面養(yǎng)護：透水混凝土由于存在大量的孔洞，易失水，干燥很快，所以養(yǎng)護非常重要.尤其是早期養(yǎng)護，要注意避免地坪中水分大量蒸發(fā)。瀝青罐特點是：加熱快、節(jié)能、生產(chǎn)量大、用多少出多少不浪費、不老化、操作方便，全部附件都在罐體上、移動、吊裝、維修特別方便，固定式非常方便，本產(chǎn)品加熱160度的熱瀝青一般不會超過30分鐘通常透水混凝土拆模時間比普通混凝土短，如此其側(cè)面和邊緣就會暴露于空氣中，應(yīng)用塑料（結(jié)構(gòu):合成樹脂、增塑劑、穩(wěn)定劑、色料)薄膜(薄而軟的透明薄片)或彩條布及時覆蓋路面和側(cè)面，以保證濕度和水泥充分水化。透水混凝土應(yīng)在澆注后1天開始灑水養(yǎng)護，淋水時不宜用壓力水柱直沖混凝土表面，這樣會帶走一些水泥漿，造成一些較薄弱（解釋:單薄而不堅強)的部位，但可在常態(tài)的情況下直接從上往下澆水。透水混凝土的澆水養(yǎng)護時間應(yīng)不少于7天。

Asphalt cement spreader construction pavement maintenance: pervious concrete due to the existence of a large number of holes, easy to lose water, dry quickly, so the maintenance is very important. Especially in the early maintenance, we should pay attention to avoid a lot of evaporation of moisture in the floor. The characteristics of asphalt tank are: fast heating, energy saving, large production capacity, no waste, no aging, convenient operation, all accessories are on the tank, especially convenient for moving, hoisting and maintenance, and fixed type is very convenient. The hot asphalt heated by 160 ℃ of this product generally does not exceed 30 minutes, and the time for demoulding pervious concrete is usually shorter than that of ordinary concrete, so the side and edge of the tank are very convenient Will be exposed to the air, the application of plastic (structure: synthetic resin, plasticizer, stabilizer, pigment) film (thin and soft transparent sheet) or color strip cloth in time to cover the road and side, to ensure the humidity and cement hydration. The pervious concrete should be watered for curing one day after pouring, and it is not suitable to use the pressure water column to directly flush the concrete surface during watering, which will take away some cement slurry and cause some weak parts (explanation: thin but not strong), but it can be watered directly from top to bottom under normal conditions. The watering and curing time of pervious concrete shall not be less than 7 days.
