沥青混凝土路面的正确施工工艺流程
来源:/ 日期:2022-10-19
现在很多城市修建的都是沥青路,那么沥青混凝土路面施工工艺流程是怎么样的呢,和济南沥青砼厂家一起来看看吧。
Nowadays, asphalt roads are built in many cities. How about the construction process of asphalt concrete pavement? Let's have a look with the asphalt concrete manufacturers in Jinan.
一、沥青混凝土路面施工工艺流程是怎么样的?
1、 What is the construction process of asphalt concrete pavement?
1、对施工地面进行封层,将基层清扫干净。
1. Seal the construction ground and clean the base course.
2、对路面铺平和预热,采用人工摊铺的方法,边施工边用耙子弄平。
2. The pavement shall be paved and preheated manually, and leveled with a rake at the same time of construction.
3、使用机器进行轧制,轧制主要分为三个阶段:初始压力、复压和中压,直到去除分离的接缝为止。
3. Rolling is carried out by machine, and the rolling is mainly divided into three stages: initial pressure, re pressing and medium pressure until the separated joints are removed.
4、等待地面完全冷却就可以通车了。
4. Wait for the ground to completely cool down before opening to traffic.
二、沥青混凝土后场施工注意事项有哪些?
2、 What are the precautions for asphalt concrete backyard construction?
1、选择混合机械设备,以确保混合机械设备的中,前院施工质量。对于以搅拌机为管理中心的沥青搅拌站,沥青搅拌机的特性和产量是关键。为了确保搅拌设备的产量与工程水平相匹配,搅拌设备须具有用于整个过程的自动控制系统。
1. The mixed mechanical equipment shall be selected to ensure the construction quality of the middle and front yard of the mixed mechanical equipment. For asphalt mixing plant with mixer as the management center, the characteristics and output of asphalt mixer are the key. In order to ensure that the output of the mixing equipment matches the engineering level, the mixing equipment must have an automatic control system for the whole process.
2、为确保原料质量,要确保这一点,一步是检查沥青混合料。从工艺性能和结构类型来看,这两个指标确实很难。粗沥青混合料应注意粒度,外观,柔软度和附着力指标。
2. To ensure the quality of raw materials, the first step is to check the asphalt mixture. From the perspective of process performance and structure type, these two indicators are really difficult. The coarse asphalt mixture shall pay attention to the particle size, appearance, softness and adhesion indexes.
在签订供应合同时,要注意确保粗沥青混合料筛选比的遗传变异较小,并确保将沙石,石灰石和大理石等弱颗粒的成分控制在有效范围内。细沥青混合料应注意砂当量(或0.075组成)和附着力的指标值,并应严格控制砂子。
When signing the supply contract, pay attention to ensure that the genetic variation of the screening ratio of coarse asphalt mixture is small, and ensure that the composition of weak particles such as sand, limestone and marble is controlled within the effective range. The index value of sand equivalent (or 0.075 composition) and adhesion shall be paid attention to for fine asphalt mixture, and the sand shall be strictly controlled.
3、进入现场后,立即建造一个防水,防雨和防晒的棚子。注意所有沥青混合物的分类和存储,请勿将它们混合在一起。为了避免原料混凝土的偏析,该部位应坚硬地铺底,并应使用水平或陡峭的斜坡层进行堆放,不允许圆锥堆叠。沥青原料需要从粘度等指标值入手,以确保高质量的沥青指标值并符合设计方案。
3. After entering the site, immediately build a waterproof, rainproof and sunscreen shed. Pay attention to the classification and storage of all asphalt mixtures, and do not mix them together. In order to avoid segregation of raw material concrete, this part should be paved hard, and should be stacked with horizontal or steep slope layers. Conical stacking is not allowed. Asphalt raw materials need to start with viscosity and other index values to ensure high quality asphalt index values and meet the design scheme.
