This utility model discloses a crack-resistant cold recycled pavement structure, belonging to the field of recycled pavement technology. Key technical features include a supporting base course, a cold recycled base course on top of the supporting base course, a crack-resistant transition layer on top of the cold recycled base course, a drainage bonding layer on top of the crack-resistant transition layer, and a functional surface layer on top of the drainage bonding layer. Through the combined design of the crack-resistant transition layer, fiberglass grid, and emulsified asphalt bonding layer, the pavement's crack resistance is significantly improved. The crack-resistant transition layer has good flexibility, buffering temperature stress and vehicle load impact. Furthermore, the fiberglass grid, embedded in the center of the crack-resistant transition layer, utilizes its high strength to disperse stress at the crack tip, preventing upward reflection of base course cracks. Combined with the emulsified asphalt bonding layer, it enhances the bonding force between structural layers, preventing interlayer slippage and the generation of new cracks, thus reducing the overall occurrence of reflective and longitudinal cracks.
