ABSTRACT
Pavement cracking has been a troublesome problem in pavement engineering, and one of the most important reasons for pavement cracking is the cracking of the pavement base. This paper first analyzes five reasons that may lead to the cracking of the cement-stabilized pavement base by comprehensively studying a large body of literature, combining the characteristics of cement-stabilized bases and environmental factors that may affect the properties of cement. It is concluded that the possible causes of cracking of cement-stabilized pavement bases are drying shrinkage, temperature shrinkage, excessive loading, raw materials, and mixture gradation. In addition, this paper also obtains the development law of cracks in the pavement base through the research of literature, which is beneficial to the in-depth study of crack control. Finally, this paper proposes two solutions commonly used in current engineering to solve the cracks of the cement-stabilized pavement base: adding fiber materials and micro-cracks. In future research, this paper will focus on other methods to solve the cracking of the cement-stabilized pavement base to accommodate various problems that may be encountered in engineering.
