摘要The technical characteristics combined with the pre-crack at home and abroad present the early strength of grassroots without the material repair technology.However,the grassroots space mesh microcracks must be implemented in the early period of heavy traffic, and widely related transverse cracks reflective of asphalt pavement cracking probability, which decreases asphalt pavement status, are also improved; a finite element method was analyzed to simulate the ideal type of crack between the two kinds of mechanical asphalt pavement crack under the form of responses, and the surface layer of microcracking technology life asphalt pavement is calculated. This study found that the microfracturing technique reduced the life of the asphalt surface to some extent. However, to solve the problems of the conventional repair techniques for readily reflective cracks and to achieve a rapid restoration of the technical requirements, a microcracking technology rapid repair in the grassroots has indicated a certain feasibility.Considering that crack forms are drawn, the fatigue life of the asphalt surface,the definition and control of the size of the cracks in the construction, and other related issues require further studies under actual crack forms.
