沥青砼的施工注意什么
来源：/ 日期：2023-07-21
沥青砼是一种常用的道路材料，也被称为沥青混凝土或沥青路面。它由矿料（如骨料、沙子等）、沥青和一定量的水混合而成。沥青是一种黑色的胶状物质，其主要成分是沥青质和矿物质。在制作沥青砼时，矿料和沥青会通过高温混合，并在固化后形成坚固的路面。
Asphalt concrete is a commonly used road material, also known as asphalt concrete or asphalt pavement. It is made by mixing mineral materials (such as aggregates, sand, etc.), asphalt, and a certain amount of water. Asphalt is a black colloidal substance, mainly composed of asphaltene and minerals. When making asphalt concrete, mineral materials and asphalt are mixed at high temperatures and solidified to form a sturdy road surface.
济南沥青砼施工时需要注意以下几点：
The following points need to be noted during the construction of asphalt concrete in Jinan:
预处理：在进行沥青砼施工前，需要确保基础地面平整、结实，并尘土和杂质，以确保沥青能够充分附着。
Pre treatment: Before carrying out asphalt concrete construction, it is necessary to ensure that the foundation ground is flat and sturdy, and to remove dust and impurities to ensure that the asphalt can fully adhere.
温度控制：沥青砼施工的环境温度应在5℃以上，低于此温度会使沥青凝固，影响施工质量。同时，在高温条件下，要适当增加施工速度，避免沥青过早干燥。
Temperature control: The ambient temperature for asphalt concrete construction should be above 5 ℃, below which the asphalt will solidify and affect the construction quality. At the same time, under high temperature conditions, it is necessary to increase the construction speed appropriately to avoid premature drying of asphalt.
沥青料选择：根据不同的工程需求，选择适合的沥青材料，如常规沥青、改性沥青等。
Asphalt material selection: Based on different engineering needs, choose suitable asphalt materials, such as conventional asphalt, modified asphalt, etc.
施工工艺：沥青砼施工一般分为铺筑、压实和养护三个阶段。在铺筑过程中，要确保沥青的均匀性和密实性，避免出现空洞和漏铺现象。压实过程中，可采用机械振动器或压路机进行均匀压实，以提高沥青砼的密实度。在养护阶段，要注意保持施工部位的湿润，避免过早负荷和损坏。
Construction process: Asphalt concrete construction is generally divided into three stages: paving, compaction, and maintenance. During the paving process, it is necessary to ensure the uniformity and compactness of the asphalt to avoid voids and missed paving. During the compaction process, mechanical vibrators or rollers can be used for uniform compaction to improve the compactness of asphalt concrete. During the maintenance phase, attention should be paid to keeping the construction site moist to avoid premature loading and damage.
措施：在施工现场设置警示标识和警戒线，确保工作区域。施工人员应佩戴个人防护装备，如帽、防滑鞋等，并遵守相关操作规程，注意自身。
Safety measures: Set up warning signs and warning lines on the construction site to ensure the safety of the work area. Construction personnel should wear personal protective equipment, such as safety helmets, anti-skid shoes, etc., and follow relevant operating procedures to pay attention to their own safety.
Please note that the above suggestions are for reference only, and the specific construction requirements should also be determined based on the actual situation and relevant specifications. Before carrying out any construction work, it is essential to consult professionals and comply with local construction regulations and standards.
