A construction method of a high-durability elastic pavement is provided to increase binding strength between a base layer and a chip layer and to increase durability of a pavement. The construction method of a high-durability elastic pavement comprises the steps of mixing a binder and additives to recycled aggregate or artificial aggregate, 100 percent passing the 19mm sieve, 80-100 percent passing the 13mm sieve, 10-40 percent passing the 5mm sieve and 0-30 percent passing the 2.5mm sieve, paving and tamping the mixed concrete to make more than 50 percent of the surface pore have a minimum size of 5mm or more, spraying primer composed of 65-75 weight percent polytetramethylene glycol, 5-10 weight percent PBG, 15-20 weight percent MDI, 1.5-2.5 weight percent TDI and 2-4 weight percent ethylenediamine on the pavement surface, and paving chips formed by mixing 65-75 weight percent chips containing anions and far-infrared emitting materials, 100 percent passing the 6mm sieve, 80-100 percent passing the 4mm sieve and 0-25 percent passing the 1.5mm sieve, and 25-35 weight percent binder on the pavement surface applied with the primer to place the chips into a gap of the pavement surface of a base layer and tamping to make more than 50 percent of the surface pore have a minimum size of 1mm or more.
