PROBLEM TO BE SOLVED: To provide a pavement reinforcing sheet restricting the entanglement of glass fiber yarns on a cutting machine when the sheet is cut, while maintaining a reflection crack prevention effect.SOLUTION: A pavement reinforcing sheet is configured by including an asphalt-based material and a glass fiber textile included therein and having a hole structure woven by using glass fiber yarns as warps and wefts, thus using the glass fiber yarns as a composition to improve the elastic modulus as compared to that of a conventional pavement reinforcing sheet. Meanwhile, the glass fiber yarns are strengthened while the yarn count of the glass fiber yarn is 500 to 2,000 tex and the thickness thereof is 0.3 to 0.9 mm, the ratio of the glass fiber textile with respect to the total mass of the pavement reinforcing sheet is 10 to 50 mass%, and the yarn count of the glass fiber yarn is thinned and the thickness of the textile is thinned. Thereby, the sheet can be suitably crushed when it is cut while maintaining a reflection crack prevention effect, and the glass fiber yarns are prevented from being entangled in a cutting machine. |
