Statistical Analysis and Evaluation of the Depth of the Ruts on Lithuanian State Significance Roads Lietuvos valstybin s reik m s keli asfalto dangos prov gylio statistinis tyrimas ir vertinimas

The aim of this work is to gather information about the national flexible pavement roads ruts depth, to determine its statistical dispersijon index and to determine their validity for needed requirements. Analysis of scientific works of ruts apearance in the asphalt and their influence for driving is presented in this work. Dynamical models of ruts in asphalt are presented in the work as well. Experimental outcome data of rut depth dispersijon in the national highway of Lithuania Vilnius – Kaunas is prepared. Conclusions are formulated and presented.
