A method for recycling in place an asphalt mixture layer of a paved road continuously, while moving a self-propelled vehicle system, which comprises a step of heating and softening the asphalt mixture layer, a step of scraping and breaking said hot and softened asphalt mixture layer and keeping the softened mixture at a temperature sufficient not to form an aggregate, to prepare an asphalt mixture having a single-grained structure, a sieving step of classifying said asphalt mixture having a single-grained structure into a plurality of grain size groups, a step of designing mix proportions for converting said asphalt mixture to a recycled asphalt mixture by the use of said plurality of grain size groups classified, a step of mixing uniformly said recycled asphalt mixtures having designed mix proportions, and a step of spreading and compacting said recycled asphalt mixtures having been mixed uniformly, to thereby form a recycled asphalt mixtures layer.
