Zusammenfassung: | The invention relates to an HMA/CC (Hot-Mix Asphalt)/(Cement Concrete) composite type pavement structure and a constructing method thereof. The composite type pavement structure comprises a roadbed layer, wherein an emulsified asphalt dilute slurry seal layer, a cement concrete slab layer, a clamped rib layer and a hot mix asphalt layer are sequentially paved on the roadbed layer. The pavement structure mainly presents the characteristic of rigidness and also has flexibility; the asphalt layer can be used for greatly relieving impacts of vehicles to the pavement board; the clamped rib layer in the structural system has the advantages of small material modulus, high viscosity and good elasticity recovery performance and can be used for better absorbing stress generated by deformation of a cement concrete slab and effectively suppressing the transmission of reflection cracks; and the emulsified asphalt dilute slurry seal layer can be used as a powerful measure of preventive curing, greatly and can improve the w |
