沥青水泥撒布车施工路面怎么做?使用透水混凝土的施工步骤有那几点?为了沥青水泥撒布车施工路面的使用效果发挥大的作用，下面是详细的介绍：

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:

沥青水泥撒布车施工路面就是把高标号水泥（材料:粉状水硬性无机胶凝材料)，6mm粒径大小的小米石加上一些添加剂，按照一定比例搅拌摊铺而成的。

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.

沥青撒布车施工路面详细施工步骤主要有五步：

The detailed construction steps of asphalt spreader are as follows:

搅拌：透水混凝土拌合物中水泥（材料:粉状水硬性无机胶凝材料)浆的稠度较大，且数量较少，为了便水泥浆能保证均匀（jūn yún)地包裹在骨科上，宜采用强制式搅拌机，搅拌时间为5分钟以上。彩色防滑路面是一种崭新的路面美化技术，可让传统的黑色沥青混凝土和灰色水泥混凝土的路面，通过彩化施工达到路面色彩赏心悦目，同时具有防滑效果

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

浇筑：在浇筑之前，路基必须先用水湿润。否则透水混凝土快速失水份会减弱骨料间的粘结强度。由于透水混凝土拌合物比较干硬，将拌和好的透水混凝土和好的透水混凝土材料铺在路基上铺平即可。

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.
              

振捣：在浇注过程中不宜强烈振捣或夯(hāng)实。一般用平板振动器(操作方式:气动阀)轻振铺平后的透水性混凝土混合料，但必须注意不能使用高频振捣器，否则他会使混凝土过于密实面减少孔隙率，并影响透水效果。同时高频振捣器也会使水泥（材料:粉状水硬性无机胶凝材料)浆体从粗骨料表面离析出来，流入底部形成一个不透水层，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.

辊（gǔn)压：振捣以后，应进一步采用实心钢管或轻型压路机压实压平透水混凝土拌合料，考虑到拌合料的稠度和周围温度等条件，可能需要多次辊压，但应注意，在辊压前必须清理辊子，以防粘结骨料。彩色防滑路面防滑涂料按施工方式分为热熔型和冷涂型两类；按抗滑性高低，分为普通防滑型、中防滑型、高防滑型三类。冷涂型按干燥速度分为快干型和慢干型。高摩擦系数的彩色防滑路面，有效地提高行车安全。

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.

沥青水泥撒布车施工路面养护：透水混凝土由于存在大量的孔洞，易失水，干燥很快，所以养护非常重要.尤其是早期养护，要注意避免地坪中水分大量蒸发。沥青罐特点是：加热快、节能、生产量大、用多少出多少不浪费、不老化、操作方便，全部附件都在罐体上、移动、吊装、维修特别方便，固定式非常方便，本产品加热160度的热沥青一般不会超过30分钟通常透水混凝土拆模时间比普通混凝土短，如此其侧面和边缘就会暴露于空气中，应用塑料（结构:合成树脂、增塑剂、稳定剂、色料)薄膜(薄而软的透明薄片)或彩条布及时覆盖路面和侧面，以保证湿度和水泥充分水化。透水混凝土应在浇注后1天开始洒水养护，淋水时不宜用压力水柱直冲混凝土表面，这样会带走一些水泥浆，造成一些较薄弱（解释:单薄而不坚强)的部位，但可在常态的情况下直接从上往下浇水。透水混凝土的浇水养护时间应不少于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.
