An object of the present invention is to provide a method for constructing a base course without rolling compaction, in which a compacting step by rolling compaction and further adjustment of the water content of the mixture to the optimum water content are not necessary, and to provide a mixture for base course, which enables the said method. The above object is attained by providing a method for constructing a base course without rolling compaction, which comprises a step of obtaining a mixture by mixing an aggregate, an asphalt emulsion, and a cement, wherein the mixture is in a high-water-content state in which a water content of the mixture is above an optimum water content of the aggregate, and a step of spreading the mixture; and which does not comprise a step of rolling compaction, and by providing a mixture for a base course, comprising an aggregate, an asphalt emulsion, and a cement, wherein the mixture is in a high-water-content state in which a water content of the mixture is above an optimum water content of the aggregate.

An asphalt pavement modification system and method for improving aging resistance of asphalt pavement and a method of manufacturing reclaimed asphalt pavement. The asphalt pavement modification system and method include using one or more antioxidants and one or more recycling agents in a blended binder to provide improved short term and long term performance of the asphalt pavement. The method of manufacturing reclaimed asphalt pavement includes mixing at least one antioxidant with at least one recycling agent to form a binder that constitutes a portion of the reclaimed asphalt pavement. One of the antioxidants may be zinc diethyldithiocarbamate.
