Embodiment 1
[0031] Example 1 An HMA / CC composite pavement structure, including a road base 5, on which an emulsified asphalt slurry seal layer SS (0.8-1.2 cm) 4, a cement concrete slab CC (22 ~26cm) 3. Reinforcement layer 2, hot mix asphalt layer HMA (4~8cm) 1; the reinforcement layer 1 is a geotextile layer.
[0032] The construction method of the above-mentioned HMA / CC composite pavement structure:
[0033] (1) Laying of road base 5: Before building the road base, implement corresponding treatment measures on the soft soil section; road base 5 should have sufficient strength, rigidity and water stability to provide continuous and uniform support for the road surface, and the top surface should also be Flat, with the same transverse slope as the surface layer to ensure uniform thickness of the surface layer. Compared with the base layer of asphalt concrete pavement as the main stress layer, the strength and stiffness requirements of cement concrete pavement can be reduced, but water stab...
