Separate construction method of cement stabilized macadam layer

A method for divide joint construction of cement stabilized macadam lay includes cutting joint at low fill road section, arc starting point in road, road fill-excavation junction and road middle line;Tank filling at the joint cut; The splitting construction of cement stabilized macadam layer can be completed by laying anti-cracking sticker on the upper part of the joints which have been poured. In the process of the invention, a polyester mortar mixture is provided, and the composition comprises polyurethane or polyvinyl chloride mortar, expanded graphite, bentonite or kaolin, fly ash and water. By adopting the technical scheme of the invention, the water-stable layer segmentation construction method is applied, the road surface layer rerepair rate is reduced, and no cracks on the road surface layer are realized during the warranty period. Mainly through the pre-asphalt pavement construction on the water-stable layer of pre-cut joint, the road at the junction of filling and excavation, road arcing point, arc
