Abstract: The present invention relates to a Mechanical Pavement Settlement Recorder designed for detecting and recording progressive vertical settlement and deformation of footpaths and pavement surfaces. The device provides a simple mechanical method for monitoring changes in pavement level without the need for complex electronic sensing systems or continuous power supply. The proposed recorder comprises a protective housing, top cover plate, adjustment screw, sensing rod, mechanical pointer, graduated scale, and bearing pad positioned in contact with the pavement surface. The bearing pad follows the vertical movement of the pavement, and the resulting displacement is transferred through the sensing rod to the pointer mechanism. The pointer moves relative to the graduated scale, thereby providing a direct visual indication of the amount of pavement settlement. The adjustment screw enables initial positioning and calibration of the sensing mechanism before monitoring begins. The housing protects the internal mechanical components from the surrounding environment while allowing the displacement scale and pointer to remain visible for observation and recording. As progressive settlement occurs due to ground movement, repeated loading, soil consolidation, moisture-related changes, or other causes, the corresponding vertical displacement is mechanically transmitted and indicated on the scale. The invention is particularly useful for footpaths, pedestrian walkways, pavements, and other paved surfaces where gradual deformation may occur over time. By providing a visible and mechanically recorded indication of cumulative settlement, the device can assist in early identification of pavement deformation and support periodic inspection, maintenance planning, and corrective action. The proposed device is economical, compact, mechanically operated, easy to install and maintain, and suitable for long-term monitoring of progressive pavement settlement. The invention therefore provides a practical and reliable mechanical solution for recording vertical deformation of footpaths and pavement surfaces.
