CONSTRUCTION METHOD OF MOTOR ROAD Russian patent published in 2019 - IPC E01C11/02 

FIELD: construction.

SUBSTANCE: distance between seams is determined by formula

where: L_cr is distance between expansion joints (m); H is thickness of asphalt-concrete ply (m); σ_t - strength of asphalt concrete for tension (Pa) at the lowest air temperature in the region of road construction; |Δt| is absolute value of maximum temperature difference per day (°C); k is coefficient of adhesion of asphalt-concrete layer with base (N/m³); α is coefficient of linear thermal expansion of asphalt concrete (1/°C).

EFFECT: invention relates to construction, particularly, to construction of an automobile road, in which an asphalt-concrete layer with expansion joints is made.
