Kelio dangos konstrukcijų sluoksnių stiprumo matavimo metodų analizė ir vertinimas

Abstract

One of the main parametrs, characterising road pavement quality is the strength which specify reasons to resist strains of the transport means. Assessment of the road pavement strength is comparing measured deflections chosen road section. This work analyses the strength measurement methods which were made in chosen road section with four instruments of the road pavement deflection measurement was compared. This paper presents results of strength measurement of road construction layers, research results of soil and research data analysis of chosen road section. Based on the study findings, the dependence of device measuring results is presented. The coefficients of devices measuring values reduction into the static deformation modulus are recommended.
