Abstract: Large void asphalt pavement has been widely used in my country's highway engineering construction because of its good performance in noise reduction, drainage, and anti-skid. Based on a comprehensive understanding of the road performance of large-voided asphalt mixtures, this paper analyzes and discusses the key technical points of the large-voided drainage and noise reduction asphalt pavement construction and post-construction performance testing based on specific engineering cases, in order to provide relevant professional reference.
