PAVEMENT SURFACING DESIGN Russian patent published in 2010 - IPC E01C7/00 

FIELD: personal use articles.

SUBSTANCE: pavement surfacing design consists of a multilayer base, which includes drainage layer and two layers of principal material, and the upper and lower layers of asphalt concrete pavement. The thickness layers of pavement are selected in accordance with the thickness and density of the upper layer of asphalt concrete pavement, as well as the density of the layer by the following functional dependence: h_j=(-0.342i⁴+4.004i³-15.659i²+24.413i-11.417)*h₁*ρ₁/ρ_i, where i - is the serial number of the layer, ρ_i - is density of the i-layer, h₁ and ρ₁ - are thickness and density of the upper layer of the coating.

EFFECT: increase of operational integrity and durability of non-rigid multilayer pavement surfacing.
