Research on Identification of Damage Development Mode of Rural Highway Asphalt Pavement Structure

Abstract

According to the damage condition of asphalt pavement of rural roads in Liaoning Province, five development modes of asphalt pavement damage were proposed to determine the damage condition of asphalt pavement in the investigation section. The trapezoidal and semi-trapezoidal membership functions are used to construct the membership matrix, and the fuzzy comprehensive evaluation model is established, and the weight vector of each factor is determined. Finally, fuzzy mathematics is used to determine the stage of the general development period of the structural damage of the road segment. The research results have certain guiding significance for the management and maintenance of rural road asphalt pavement in Liaoning Province.
