1、透水瀝青路面結(jié)構(gòu)層可以是表層基層基層墊層的組成。透水瀝青路面本身的瀝青結(jié)構(gòu)層屬于柔性路面類，但除柔性材料外，基層可由剛性水泥混凝土或半剛性水硬材料制成。透水瀝青路面表層是直接承受車輪載荷和自然因素的重復(fù)影響的結(jié)構(gòu)層，可以由1至3層組成。

1. The permeable asphalt pavement structure layer can be composed of a surface layer, a base layer, and a cushion layer. The asphalt structural layer of the permeable asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can be made of rigid cement concrete or semi rigid hydraulic materials. The surface layer of permeable asphalt pavement is a structural layer that directly bears the repeated influence of wheel loads and natural factors, and can be composed of 1 to 3 layers.

2、基材的強(qiáng)度指標(biāo)應(yīng)有較高的要求?；鶎臃胖迷诒砻鎸酉旅妫⑴c表面層一起將輪載荷的重復(fù)效應(yīng)擴(kuò)展到基層墊土基，其作為主要承重層。密集穩(wěn)定的瀝青層中間層下層應(yīng)根據(jù)道路等級(jí)瀝青層厚度氣候條件等選擇。表面層應(yīng)根據(jù)使用要求設(shè)置防滑和耐磨。

2. The strength index of the substrate should have high requirements. The base layer is placed below the surface layer and, together with the surface layer, extends the repeated effect of wheel load to the base layer cushion, which serves as the main load-bearing layer. The dense and stable asphalt layer should be selected based on road grade, asphalt layer thickness, climate conditions, and other factors. The surface layer should be set with anti slip and wear resistance according to the usage requirements.

3、基材的強(qiáng)度指數(shù)要求略低于基材。根據(jù)道路的水平或交通量，子基地可以設(shè)置為一層或兩層。當(dāng)基層較厚并需要分成兩層時(shí)，它可以稱為上基層下基層。墊層是設(shè)置在基層和土壤基礎(chǔ)之間的結(jié)構(gòu)層，排水為水分離防凍防污等。基準(zhǔn)水平可以設(shè)置為一層或兩層，具體取決于道路的水平或交通量。當(dāng)基層較厚并需要分為兩層時(shí)，它可以稱為基層下的上基層。子基層位于基層下方，并且表面層為基層，以承受車輪負(fù)載和次級(jí)承載層的重復(fù)影響。

3. The strength index requirement of the substrate is slightly lower than that of the substrate. According to the level of the road or traffic volume, the sub base can be set up as one or two floors. When the base layer is thick and needs to be divided into two layers, it can be called the upper base layer and the lower base layer. The cushion layer is a structural layer set between the base layer and the soil foundation, and the drainage is water separation, anti freezing, and anti fouling. The benchmark level can be set to one or two levels, depending on the level of the road or traffic volume. When the base layer is thick and needs to be divided into two layers, it can be called the upper base layer below the base layer. The sub base layer is located below the base layer, and the surface layer is the base layer to withstand the repeated influence of wheel load and secondary bearing layer.

4、以前的彩色瀝青混凝土生產(chǎn)工藝都是采用采用成品彩色瀝青經(jīng)過脫桶再生與生產(chǎn)黑色瀝青混凝土相同的工藝進(jìn)行生產(chǎn)。也就是把黑色的瀝青油換成彩色瀝青油就可以了。而現(xiàn)在國內(nèi)比較流行的工藝所采用的膠結(jié)料為經(jīng)過脫色的淺色彩色瀝青專用膠結(jié)料，經(jīng)脫筒計(jì)量后進(jìn)入拌缸和骨料，礦粉等材料一起攪拌，再在攪拌過程中加入所要添加的顏料，攪拌均勻后即成為成品彩色瀝青混凝土。

4. The previous production process of colored asphalt concrete used the same process as producing black asphalt concrete by using finished colored asphalt that was regenerated after being removed from the barrel. That is to replace the black asphalt oil with colored asphalt oil. The currently popular process in China uses a light colored asphalt special binder that has been decolorized. After being measured and removed from the drum, it enters a mixing tank and is mixed with materials such as aggregates and mineral powder. During the mixing process, the pigment to be added is added, and after mixing evenly, it becomes the finished colored asphalt concrete.

5、成品彩色透水瀝青油由于色彩品種繁多，如要生產(chǎn)多種顏色品種的混凝土，則需要多個(gè)裝不同顏色透水瀝青油的儲(chǔ)罐，而新工藝采用脫色透水瀝青，只需一個(gè)儲(chǔ)罐即可，在攪拌缸中添加不同顏色的顏料即可得到不同顏色的透水瀝青混凝土。

5. Due to the wide variety of colors in the finished color permeable asphalt oil, multiple storage tanks with different colors of permeable asphalt oil are required to produce concrete of various colors. The new process uses decolorized permeable asphalt, which only requires one storage tank. By adding different colors of pigments in the mixing tank, different colors of permeable asphalt concrete can be obtained.

6、采用成品彩色透水瀝青時(shí)，若要變換使用的透水瀝青油顏色，殘留在公共管道中的上一次使用的透水瀝青油顏色就會(huì)污染下一次使用的采油顏色，這對(duì)產(chǎn)品外觀造成較大的影響，同時(shí)由于成品彩色透水瀝青價(jià)格高，這也是一種不小的浪費(fèi)，為防止不同顏色的透水瀝青相互污染，不同色彩的透水瀝青采用不同的脫桶設(shè)備和輸出管道

6. When using finished colored permeable asphalt, if the color of the permeable asphalt oil used needs to be changed, the color of the previous used permeable asphalt oil remaining in the public pipeline will pollute the color of the next used oil extraction, which has a significant impact on the appearance of the product. At the same time, due to the high price of finished colored permeable asphalt, this is also a significant waste. To prevent mutual pollution of different colored permeable asphalt, Different colors of permeable asphalt use different stripping equipment and output pipelines
