This paper examines the problem of heavy construction vehicle traffic during daytime hours in Astana, Kazakhstan, and its multi-dimensional negative effects on road infrastructure, ecology, and traffic safety. The study aims to provide a technical, economic, and legal justification for introducing a daytime movement restriction (07:00–20:00) for heavy construction vehicles over 15 tonnes via road sign 3.4, enforced through the existing Automated Fixed Violation Recording (AFVR) system. Methods applied include comparative and systems analysis, technical-economic assessment, regulatory analysis, and international benchmarking. Using the AASHTO fourth-power law, the study establishes that actual rear-axle loads of overloaded dump trucks (up to 36 t vs. the 16 t standard) produce destructive pavement impacts equivalent to 25,600 passenger cars per trip. A comparative review of 63 world cities confirms that Astana is the only CIS capital lacking a systematic daytime restriction on heavy construction vehicles. The proposed 'road sign 3.4 + AFVR' model requires a one-time investment of 25–45 million KZT and is projected to generate an annual economic benefit of 8–15 billion KZT through reduced road repair expenditure, lower accident rates, and the elimination of corruption risks
