Abstract

This article provides a summary of the author’s PhD thesis on possibilities for the improvement of the quality of design solutions in gravel road reconstruction projects. The thesis includes five chapters: analysis of the Gravel Road Network in Lithuania and analysis of the gravel roads development; analysis of the road design standards of the Republic of Lithuania compared to other countries; methodology of experimental investigations; results of the investigations; and conclusions based on the investigation results. In this work, the author proposes a new road design methodology in which road alignment is characterized as a sequence of successive interrelated elements, including traffic safety criteria. The author concludes that present regulations for road design in the Republic of Lithuania are inaccurate and deficient and should not be used for road reconstruction projects, particularly on gravel roads. Recommended corrections and supplements to these regulations are presented. The original thesis, in Lithuanian, is available upon request from the author.
