Features: This book utilizes the world's advanced road testing equipment Dynatest 8000 Falling Weight Deflectometer (FWD) to conduct on-site measurements of several asphalt pavement sections on the main roads of Puyang City. Based on the test results, the flexible pavement back-analysis software is used to identify the technical condition and evaluation results of each section. The book summarizes the variation patterns of asphalt pavement strength and then employs scientifically sound and reasonable maintenance strategies to achieve the goals of extending the service life of highways and reducing maintenance costs. The book is divided into 9 chapters, covering topics from road deflection testing equipment and its technical performance to the mechanical analysis of asphalt pavement structures, summarizing the variation patterns of asphalt pavement strength and quality evaluation, finally selecting reasonable and scientific maintenance strategies for asphalt pavements. Based on the relevant specifications issued by the Ministry of Transport, the book summarizes practical experiences and insights from work practice, proposing advanced and effective highway maintenance technologies for reference by highway technical management personnel in their actual work.
