Description

Technical Field

[0001] This utility model relates to the field of road engineering, and in particular includes a road roller suitable for real-time detection of the compaction degree of ultra-high phosphogypsum pavement base course. Background Technology

[0002] Phosphogypsum is a byproduct of wet phosphoric acid production. Large-scale stockpiling of phosphogypsum not only occupies vast amounts of land and incurs significant maintenance costs, but improper storage can also cause severe environmental pollution, seriously hindering the healthy development of my country's phosphate chemical industry. Therefore, various industries are exploring ways to utilize phosphogypsum resources. Using phosphogypsum as a road base material is an effective approach, and road base materials with full phosphogypsum admixture represent the most efficient method for phosphogypsum utilization.

[0003] Compaction degree is a crucial indicator of the construction quality of road base courses, directly affecting the strength, stability, and service life of the road structure. Several methods exist for testing the compaction degree of road base courses, including the sand cone method, ring cutter method, core drilling method, and nuclear density meter method. Among these, the sand cone method, ring cutter method, and core drilling method require on-site drilling by technicians, demanding high skill levels. The data calculation process is cumbersome, and repairs to the sampling points are necessary after testing, resulting in low efficiency. Furthermore, only one point can be tested at a time, hindering rapid large-scale testing. The nuclear density meter method determines the density and moisture content of the material based on the scattering or absorption of radiation in the base course, thus calculating the compaction degree. This method provides rapid compaction results, but the released radiation during the measurement process is radioactive and may cause irreversible harm to the human body. Therefore, there is an urgent need for a rapid method or device capable of detecting the compaction degree of road base courses over a large area.

[0004] Several publicly available technical solutions exist for real-time detection of the compaction degree of road structures. CN119023944A discloses a self-vibration detection device and method for asphalt mixture compaction quality. This method constructs a model relating compaction degree to acceleration and temperature, and uses infrared temperature and acceleration sensors to collect temperature and acceleration data in real time, enabling real-time detection of the compaction degree of the asphalt surface layer. However, this solution relies on measuring the compaction degree through the temperature and acceleration of the asphalt concrete. Since the road base layer is constructed at room temperature, this technical solution is not suitable for rapid detection of the compaction degree of the base layer.

[0005] CN210827406U discloses a real-time detection mechanism for the compaction degree of ultra-thick cement-stabilized crushed stone base courses. Its principle is to obtain compaction height data from dynamic distance sensors at both ends of the roller, and then integrate and compare this data to obtain the final compaction degree information. The drawback of this solution is that while it achieves high accuracy when the cement-stabilized crushed stone base course is thick, the thickness of a powder system without a crushed stone skeleton, such as a full-dosage phosphogypsum base course, is often lower when layered and compacted. Therefore, the technical solution disclosed in CN 210827406U is not suitable for rapid compaction degree detection of full-dosage phosphogypsum base courses. Utility Model Content
