Description

A road roller with road compaction detection function Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a road roller with a road compaction degree detection function. Background Art

[0002] At present, the main research contents of road researchers in my country involve asphalt mixture design theory, road materials, construction technology, and maintenance. However, there is little in-depth research on the quality control and management of highway asphalt pavement construction.

[0003] my country's current asphalt pavement construction specifications largely lack specific information on management models, procedures, or methods, let alone intelligent construction process control methods or systems. When it comes to asphalt pavement construction quality management, most adopt the traditional "results-based testing" approach. Whether it's sampling, extraction, screening, or indoor Marshall testing of asphalt mixtures, or post-paving quality inspections such as pavement compaction and smoothness, results are often delayed by 2-3 days, causing testing and inspection to lag behind the production process. Furthermore, when pavement construction quality issues arise, it's impossible to trace the source or identify the construction link where the problem occurred. Therefore, rapidly, promptly, and accurately collecting construction process data, monitoring construction quality in real time, and making intelligent judgments to provide effective guidance to construction equipment are key to improving current highway construction technology.
