摘要
PROBLEM TO BE SOLVED: To provide polymer cement mortar which can be applied in a concrete slab-asphalt pavement road surface even when deterioration develops to a concrete slab, and a repair method using the polymer cement mortar.;SOLUTION: Polymer cement mortar contains quick-hardening cement, a polymer for cement, a fine aggregate, and water, and has a unit polymer content of 50-150 kg/m3, a water/cement ratio of 26-35%, and a polymer/cement ratio of 10-30%. A repair method includes: a step A of removing an asphalt layer 5 including a deteriorated part and concrete 3 under the asphalt layer 5 to form a hollow 9 in a concrete slab 1; a step B of filling polymer cement mortar 10 into the hollow 9 of the concrete slab 1; and a step C of laminating an asphalt layer 12 on the upper surface of the hardened polymer cement mortar 10.;COPYRIGHT: (C)2014,JPO&INPIT
