Ultrathin composite structure layer for preventing reflection cracks and preparation method of ultrathin composite structure layer
The invention discloses an ultrathin composite structure layer for preventing reflection cracks and a preparation method of the ultrathin composite structure layer. The ultrathin composite structure layer comprises an anti-sliding high-strength geogrid layer, a lower toughening type epoxy asphalt layer, a lower graded macadam layer, an upper reinforced type epoxy asphalt layer and an upper graded macadam layer which are arranged on a cement pavement from bottom to top in sequence. The composite structure layer disclosed by the invention is a complex and solid interlocking system which is excellent in anti-pull, anti-shearing, adhesive and waterproof property, has very good tensile, anti-shearing and stress absorption functions when strain is relatively small, is capable of effectively reducing reflection cracks of an additionally paved asphalt concrete layer on the cement pavement and effectively reducing the self-weight, and is relatively low in thickness, good in stability, high in anti-sliding property and relatively long in service life, the preparation method of the composite structure layer is high in mechanical degree and high in feasibility, and the additionally paved asphalt concrete layer can be directly constructed on the prepared ultrathin composite structure layer.
