Development of Assessment Methodology for Pavement Longitudinal Evenness When Road Construction Durability Changes

Purpose: To develop prognosis methodology for road pavement longitudinal evenness, depending on construction durability change (of wearing and ground roadbed) the basis of analysis existing practice relationship estimation between inner deformations undulation occurrence a pavement. Methods: Statistical analytical. Application Palmgren — Miner hypothesis dependence from actual allowable number applied calculated loads. Results: Based hypothesis, an equation to determine coefficients is proposed given linear accumulations fatigue strains versus time. Calculations are performed results obtained theoretically justified. The dependences evenness changes in coefficient highways II, III IV categories determined. Methods operative definition resource has been developed. Practical significance: methods allow value prospective period highway exploitation (for service life repairs).
