Title:
COLD-MIXED RESIN, MIXTURE AND PREPARATION METHOD THEREFOR, AND ULTRATHIN-WEARING-COURSE PAVEMENT AND PAVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/245764
Kind Code:
A1
Abstract:
A cold-mixed resin, a mixture and a preparation method therefor, and an ultrathin-wearing-course pavement and a paving method therefor. The cold-mixed resin comprises the following components in parts by weight: 10-22 parts of an epoxy resin, 25-35 parts of a vegetable oil residue extract, 10-20 parts of naphthenic oil, and 35-45 parts of polymethylene polyphenyl polyisocyanate. The open-graded cold-mixed resin mixture comprises a mineral aggregate and a cold-mixed resin. The open-graded cold-mixed resin ultrathin-wearing-course pavement comprises a bonding layer and a pavement layer, which are sequentially stacked from bottom to top, wherein the materials of the pavement layer comprise an open-graded cold-mixed resin mixture and a composite curing agent. By reasonably selecting the raw materials and the amount of the cold-mixed resin, the construction time of the open-graded cold-mixed resin mixture is prolonged; by spraying the composite curing agent on the resin mixture, the effect of quick opening to traffic is achieved; and fuel consumption and carbon dioxide emissions during a construction process are greatly reduced, and the service life of a pavement is prolonged.
