Generally, when building the pavement, the quality of asphalt, crushed stone, sand, mineral powder and other materials will be used. The mixture thus mixed is asphalt concrete. Such a proportion has strict standards, which should meet the technical requirements of relevant industry specifications. In short, the construction of Jinan asphalt concrete should be prepared in advance. The following editor will explain it for you.
Pay attention to the material selection of asphalt concrete
In fact, this is an important part of the asphalt concrete construction project, because it is related to procurement. If you want to make asphalt concrete that meets the industry specifications and standards, you need to do a good job in the selection of raw materials, so this aspect is what you need to pay attention to. When purchasing raw materials, you should master the specifications, properties, strength, certificate of conformity, shelf life Stacking site and storage conditions
In addition, pay attention to supervision and inspection during construction. This kind of material should be strictly controlled. On the one hand, the use of raw materials should be well controlled, and on the other hand, the standardization of mechanical equipment in the construction project should be well controlled. On the other hand, it is also necessary to carefully check whether the parts of the required equipment meet the requirements of technical specifications. These are some influencing factors related to the construction of asphalt concrete pavement.
Some controls during construction
In the paving of asphalt concrete pavement, there are generally two layers, one of which is paved. When the base layer is paved, there must be a certain standard to check. After passing this standard, another layer will be paved, but this paving will take place at intervals
Therefore, there will be different damages to the lower layer, some due to rain and some due to rolling by construction vehicles. Therefore, attention should be paid to the maintenance of the base layer. Various quality problems on the surface of the lower bearing layer will affect the interlayer bonding of the pavement structure and even the overall strength of the pavement.
Then, we should pay attention to the mixing of asphalt concrete, which is also a key part. During the mixing of asphalt concrete, we should control its temperature, asphalt stone ratio and material gradation, which all need to be done in strict accordance with the requirements, so professional technicians are required to be responsible.
In fact, each section of asphalt concrete pavement can only be put into use after a long time of construction. Moreover, a good pavement requires strict production and construction standards. Please come to our website for more relevant content http://www.ycgjglcl.com Consult and understand!
