The present invention relates to road structure and construction technology, and is especially road structure with flexible fiber and emulsified asphalt stabilized aggregate layer as the base layer and its construction process. The road structure includes one bottom layer; one base layer and one paved surface layer, and the base layer of rolled flexible fiber and emulsified asphalt stabilized aggregate is formed through mixing flexible fiber, emulsified asphalt, cement and water to form cementing material, adhering aggregate, stuffing, admixture, etc with the cementing material, and rolling. The rolled flexible fiber and emulsified asphalt stabilized aggregate has improved early plastic shrinking, dry shrinking and hot shrinking performance, obviously raised anticracking performance, toughness, impact strength, frost resistance, erosion resistance and water stabilty, and doubled antifatigue performance. The road with the said base layer has raised performance and increased service life.
