Full-depth ultra-thin long-life pavement structure and construction method thereof

Abstract

A full-depth ultra-thin long-life pavement structure and a construction method thereof are disclosured. The pavement structure is disposed on a subgrade, and the pavement includes from bottom to top: a composite joint layer, a fatigue-resistant layer, a load-bearing layer, a high-strength bonding layer and a skid-resistant wearing layer; the composite joint layer comprises a bottom layer and an upper layer, the bottom layer is a graded gravel layer, and the upper layer is an open-graded large-particle-size water-permeable polyurethane and gravel mixture layer; the fatigue-resistant layer is paved by a skeleton-interlocking structural polyurethane mixture; the load-bearing layer is paved by a suspended-dense typed polyurethane mixture; the high-strength bonding layer is formed by curing a polyurethane-based composite material; the skid-resistant wearing layer is paved by a high-viscosity and high-elasticity modified asphalt mixture.
