    While there are no universally accepted structural layer coefficient values for asphalt cold mix it is generally recognized that cold mix asphalt is not the structural equivalent of hot mix asphalt but is superior to gravel or crushed stone base cours Asphalt cold mix is generally not recommended for use as a wearing surface but only in The asphalt prime coat must completely penetrate the base surface in order to be effective A prime coat must completely cure before an additional layer is incorporated It is vital to be aware of weather conditions when apply an asphalt prime coat In the case of wet weather this step should be postponed to avoid runoff into the water supply
