Abstract: Combined with the actual construction project, this paper makes a statistical analysis on the surface diseases of K98+680-K151+208 of G0121 Beijing-Qinhuangdao Expressway in Tangshan City, Hebei Province, such as transverse cracks, longitudinal cracks, mapping cracks, small bare cracks and fatigue cracks, as well as the construction process, quality control points and main material technical indicators of 1 cm special modified asphalt binder micro-surface. The main technical points of 1 cm micro-surface material requirements, mix ratio design, milling, purging, viscous oil spreading, mixing, transportation, spreading, compaction, open traffic are summarized. The aim is to promote the application of 1cm special modified asphalt cement micro-cladding construction technology in highway repair and maintenance, improve the pavement damage index PCI index, further improve the pavement technical condition index PQI index, and provide construction reference and technical basis for the pavement repair construction of highway maintenance engineering in China.
