Abstract:The damage data of asphalt pavement with semi-rigid base and Composite base are summarized and analyzed, and the average types of asphalt pavement diseases, disease coverage rate and contribution rate of pavement damage derivative indicators are put forward. The analysis results show that the average types of diseases of Composite base and semi-rigid base pavement are basically the same in different periods, and the coverage and contribution rate of diseases are the four diseases of transverse crack repair, longitudinal crack repair, longitudinal crack (light), transverse crack (light), etc. The expansion speed of early micro-cracks of semi-rigid base pavement is obviously higher than that of Composite base pavement, and Longitudinal crack (serious) disease of two kinds of base pavement develops most rapidly in the same stage. Compared with semi-rigid base, Composite base delays the most rapid development of transverse cracks (heavy) and massive cracks. Composite base pavement has better maintenance elasticity than semi-rigid base pavement.
