VIBRO-ACOUSTIC CHARACTERIZATION OF ROAD CONSTRUCTION EQUIPMENT
Abstract
ABSTRACT
This study investigates the vibro-acoustic characterization of road construction equipment, specifically compactors, graders, bulldozers, and excavators, utilized in Benue State, Makurdi. The primary objectives are to characterize vibro-acoustic emissions from selected equipment, assess the impact of these emissions on workers and nearby residents, and recommend mitigative measures to safeguard health and equipment. Utilizing sound level meters and vibration meters, significant noise levels (up to 100 dBA) and vibrations (up to 2.5 m/s) were recorded, particularly from compactors and bulldozers. Findings indicate that prolonged exposure to these high noise and vibration levels poses serious risks, including hearing loss and structural damage. The study underscores the urgent need for effective noise and vibration management practices. Recommendations include regular operator training, maintenance schedules, investment in modern equipment, and community involvement in planning processes. These measures aim to enhance safety and environmental sustainability in construction activities.
