Description

Technical Field

[0001] The invention relates to the technical field of pavement construction, and in particular to a method for using a device for controlling the paving thickness of an asphalt pavement in a road engineering project. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is a high-grade pavement used in road construction. Asphalt concrete pavement refers to a pavement with asphalt concrete as the surface layer, which is a mixture of artificially selected mineral materials (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) with a certain graded composition and a certain proportion of road asphalt materials, mixed under strictly controlled conditions.

[0003] During the paving process of asphalt mixture, the thickness of the loose layer, longitudinal elevation and other parameters have a very important impact on the performance and life of the formed pavement. However, during the construction process, these parameters often deviate seriously from the specified technical requirements and have a large degree of discreteness. At present, the traditional method of using wire ropes to control the thickness of asphalt before paving asphalt may cause the asphalt to be paved too thick or not thick enough.
