The invention belongs to the technical field of cement concrete pavement construction and provides a transverse contraction joint construction method for a cement concrete pavement for solving the technical problems that according to existing cement concrete pavement cut joints, damage to the pavement is serious, the utilization amount of the joint sealing material is large and the sealing effect, driving comfort and appearance are bad. The transverse contraction joint construction method for the cement concrete pavement particularly comprises the following construction steps of joint-cutting, clearing of a cut joint, construction of joint sealing materials of a lower sealing layer, construction of joint sealing materials of a middle sealing layer, construction of joint sealing materials of an upper sealing layer and surface finishing. According to the transverse contraction joint construction method for the cement concrete pavement, different kinds of joint sealing materials are adopted for sealing joint filling in a three-layer mode. The lower sealing layer is designed as a narrow slit and the utilization amount of the joint sealing materials is reduced. Rubber strips are adopted for the middle sealing layer, the sealing effect is good, meanwhile vertical vibration of vehicles is reduced and driving comfort is realized. The light-color macromolecule joint sealing materials are adopted for the upper sealing layer, so that the color of the upper sealing layer is approximate to that of the cement concrete pavement to achieve an artistic effect.
