In response to the need for improved quality control efficiency and durability in highway engineering,a life cycle quality control strategy based on the Deming Cycle was proposed.By applying this strategy to a highway project in Beijing,the issue of unstable quality during construction was resolved.The validation found that the strategy could reduce the design cycle by 25%,lower construction costs by 4%,decrease the probability of construction accidents by 60%,reduce operational and maintenance costs by 16.67%,and extend the service life of the highway by 5 years.
