Asphalt concrete price

Asphalt concrete is very common in our life and has a great influence on our life. For example, there are many kinds of asphalt concrete, which are commonly used in our roads. Generally, it can be divided into two categories, namely petroleum asphalt and coal asphalt. The technology of asphalt concrete is also very special in the production process. For example, it is made by thermal mixing. Then Bian Xiao will tell you something about asphalt concrete.

Asphalt concrete price

Bituminousconcrete, commonly known as asphalt concrete, is a mixture of artificially selected mineral aggregate, crushed stone or gravel, stone chips or sand, mineral powder and so on. Under strictly controlled conditions, it is mixed with a certain proportion of road asphalt materials.

Asphalt concrete technology

(1) Asphalt prime oil: prime asphalt is spread on the completed lime-fly ash macadam, and the main materials are slow-cracking cationic or anionic emulsified asphalt (PC-2 or PA-2) and stone chips with a particle size of 0.5- 1.0cm, and the prime asphalt is sprayed by an asphalt distributor with the dosage of1.0l/. If there is any omission, it should be added manually. After pouring the prime asphalt, it is advisable to sprinkle stone chips or coarse sand immediately, and the dosage is 3m3/ 1000m2. Then roll it with a 6-8T steel drum roller. After paving, ensure that it will not be disturbed within 24 hours, so that asphalt can fully penetrate into the base.

2, asphalt mixture surface construction technology:

① Preparation: Two pavers are used for asphalt concrete pavement, with reference lines on both sides and aluminum beams in the middle. The distance between the two machines is about 10m. First of all, asphalt concrete pavement construction will do a good job in eight links: grass-roots acceptance, technical preparation, personnel organization, equipment organization, operation preparation, mixture transportation, mixture paving and rolling, and subbase acceptance. The indexes of base and asphalt concrete base must meet the requirements of the used specifications. The smoothness and thickness of asphalt concrete pavement must strictly meet the design requirements and lay a good foundation for the upper construction.

A. Material preparation: The asphalt mixture used in construction must be declared as required. If the approved mixture ratio changes, it needs to be declared again.

B, personnel preparation: before paving the test section, in the presence of the resident supervision office and the on-site commander, report the construction plan and hold a technical disclosure meeting to clarify the responsibilities and technical requirements of each post, so as to achieve a clear division of labor, carry out their duties in an orderly manner, and carry out the construction after approval by the resident office.

After the end of the test section, a technical summary meeting will be held, aiming at the existing problems and deficiencies, effective rectification measures will be formulated to further improve the construction technology, and comprehensive construction will be carried out after approval by the supervision engineer. On-site command and overall work coordination; On-site transportation, safety and vehicle deployment; On-site construction, subsequent operation and preparation; Take care of the baseline equipment and adjust the width and oil edge to adjust the elevation, thickness and cross slope of paving stones; Temperature measurement, rolling and testing shall be carried out by special personnel.

(2) Supervision of production, transportation and unloading of asphalt mixture: First of all, our project department entrusts the laboratory to control the production quality of asphalt, complete various indoor tests according to the requirements of specifications, and feed back the results to the supervisor in time. Without the consent of the supervisor, the mixture ratio shall not be adjusted, and manual unloading is strictly prohibited. The specialist is responsible for measuring the temperature of materials, observing the appearance quality, and preventing unqualified materials from being used in construction. Second, hot mix asphalt mixture.
