沥青混凝土是一种常用于路面建设的材料，它的特点是耐磨、耐候、耐水等，但也有一定的缺点，比如易老化、易开裂等。为了延长沥青路面的使用寿命，保护路面免受外界环境的影响，一般还会对其进行路面密封处理。

Asphalt concrete is a commonly used material in road construction, characterized by wear resistance, weather resistance, water resistance, etc. However, it also has certain disadvantages, such as easy aging and cracking. In order to extend the service life of asphalt pavement and protect it from external environmental influences, road sealing treatment is generally carried out.

那么，在沥青混凝土施工过程中，何时适合进行路面密封处理呢？实际上，对于路面密封处理的时间，有一定的要求和建议。一般来说，沥青混凝土路面施工完成后的初期就可以进行路面密封处理。

So, when is it suitable to carry out road sealing treatment during asphalt concrete construction? In fact, there are certain requirements and suggestions for the time required for road sealing treatment. Generally speaking, after the completion of asphalt concrete pavement construction, road sealing treatment can be carried out in the early stage.

在施工初期，新铺设的沥青混凝土路面还未完全固化，尚未受到外界环境的侵蚀，路面的质量相对较好。此时进行路面密封处理，可以将路面表面封闭起来，防止水分、氧气等的渗透，减少对沥青混凝土的侵蚀作用，有效延长路面的使用寿命。

In the early stages of construction, the newly laid asphalt concrete pavement has not yet fully solidified and has not been eroded by the external environment, resulting in relatively good quality of the pavement. At this time, road sealing treatment can seal the surface of the road, prevent the infiltration of moisture, oxygen, etc., reduce the erosion effect on asphalt concrete, and effectively extend the service life of the road.

根据国内外的实践和经验，一般在沥青混凝土施工完成后的1个月内，即初期施工完成后的潜伏期，是进行路面密封处理的Z佳时间。潜伏期是指沥青混凝土路面在施工后的一段时间内，路面表面逐渐固化、抗侵蚀能力逐渐增强的过程。

According to domestic and foreign practices and experiences, the optimal time for road surface sealing treatment is generally within one month after the completion of asphalt concrete construction, which is the incubation period after the initial construction is completed. The latent period refers to the process during which the surface of asphalt concrete pavement gradually solidifies and its erosion resistance gradually increases during a period of time after construction.

在潜伏期内进行路面密封处理，可以充分利用沥青混凝土的优点，保护路面免受水分、冻融、紫外线辐射等因素的损害。此外，由于路面表面尚未形成明显的裂缝和破损，进行路面密封处理也相对简单，能够保证施工质量。

Sealing the road surface during the incubation period can fully utilize the advantages of asphalt concrete and protect the road surface from damage caused by factors such as moisture, freeze-thaw, and ultraviolet radiation. In addition, due to the lack of obvious cracks and damages on the road surface, road sealing treatment is relatively simple and can ensure construction quality.

除了初期施工完成后的潜伏期外，还可以在沥青混凝土施工后的一些特定时机进行路面密封处理。比如，在沥青混凝土路面老化、开裂较严重时，可以通过路面密封处理来修复和保护路面。此外，对于一些高要求的特殊道路，如高速公路、机场跑道等，也可以在施工完成后尽早进行路面密封处理，以保证道路的使用寿命。

In addition to the incubation period after the initial construction is completed, road sealing treatment can also be carried out at specific times after asphalt concrete construction. For example, when asphalt concrete pavement is aging and cracking is severe, road sealing treatment can be used to repair and protect the pavement. In addition, for some special roads with high requirements, such as highways, airport runways, etc., road sealing treatment can also be carried out as early as possible after construction is completed to ensure the service life of the road.
