Embodiment 1
[0062] It can be seen from the accompanying drawings that a flexible roadbed asphalt concrete structure, in which:
[0063] The subbase is broken and compacted by crushing the original cement concrete pavement, and the thickness of the subbase after crushing is 25cm;
[0064] Sprinkle 50% slow-cracking emulsified asphalt on the top surface of the subbase, the dosage is 3kg / square meter;
[0065] Lay graded gravel on the subbase to form the base, the base is paved with graded gravel, and the laying thickness is 15cm;
[0066] Sprinkle 50% slow-cracking emulsified asphalt on the top surface of the base, the dosage is 2.5kg / square meter;
[0067] Lay the anti-fatigue asphalt layer on the base layer. The anti-fatigue asphalt layer is laid with AC-13 asphalt concrete. The AC-13 asphalt concrete is divided into two layings. The laying thickness is 2 layers*4cm, and the total thickness of the fatigue-resistant asphalt layer is 8cm. ;
[0068] Sprinkle modified emulsified asphalt o...
