ANALYSIS OF THE DEFORMATION OF ROAD SURFACE CONSTRUCTION BASED ON MONITORING CLIMATIC FACTORS

The article presents the results of simulation of the deformation state of a road surface structure intended for traffic categories KR 3-4. Climatic factors such as temperature and humidity were obtained from a database collected based on the installed monitoring. The performed validation of the deformation state indicated a very good fitness of the model to the experimental results, provided that the viscoelastic model. The results indicated that the difference in pavement load time between 1 s and 1200 s in summer may result in an increase in horizontal deformation under the asphalt layer by 949%, and in winter by 74%. The calculated vertical displacement in winter after 1200 seconds of loading is equivalent to the displacement calculated after 1 second of loading the road surface in summer.
