Personal research achievements: Led over 50 national level scientific research projects in Shaanxi, Gansu, Xinjiang, Sichuan, Ningxia, Guangdong, Jiangxi and other provinces. The main scientific research achievements include: 1. Created the basic theory of crack resistance mechanism and performance of semi-rigid base materials; 2. Established electronic testing methods for temperature shrinkage and drying shrinkage of semi-rigid base materials; 3. Proposed the optimal gradation of fly ash crushed stone aggregate based on comprehensive performance; 4. Established the HPFLA design method for base course mixtures based on the grading range and theoretical experience method of high-performance fly ash crushed stone base course aggregates; 5. Through nearly a decade of research on durable pavement structures and materials in two national and one provincial regions with large temperature differences, a design method for durable pavement structures and materials suitable for western regions with large temperature differences has been recommended; 6. Proposed a design method for reasonable low embankments in western desert areas considering different traffic volumes, foundation modulus, roadbed modulus, and environmental conditions; 7. Developed a TSEM tunnel specific asphalt mixture that can reduce construction smoke and dust, low noise, high anti slip durability, and high flame retardant and degradable automotive exhaust; In 2011, a new type of UTO-7 ultra-thin overlay structure and UTO-7 ultra-thin asphalt mixture and design method were established and put into use; 9. Established the PRAS embedded anti-skid green seal maintenance technology for improving the anti-skid performance of old cement concrete pavement in tunnels using water-based epoxy and emulsified asphalt composite materials; In 2012, the digital information quality control technology for asphalt pavement construction was established. In response to the requirements of new engineering development, research is currently being conducted in the direction of intelligent maintenance technology.
