On research of optimal programming solutions for road construction in modern conditions

Abstract

Abstract. The poor condition of roads in most regions of Russia predetermines the need to establish and implement target regional programs of road network development in the country. Depending on the time perspective of the mentioned programs (short, medium or long term), the defining criteria for including roadways in these programs are set. To develop the theory and practice of justification of optimal programming solutions in road construction in the context of multi-criteria assessment, the authors have proposed the method to optimize the programming solutions in road construction and the algorithm of its implementation. The basic principles of comparing alternative variants for the construction of roadways with comparable pavement design as well as recommendations on the selection of the optimal variant have been developed using the technical and economic indexes.

Evaluation of the effectiveness of methods of compaction of sandy soil using physical modeling in the laboratory

“…It is known that security of the system «construction-base» is determined by security of every element within this system [4]. That is why the condition of the road surface or appearance of additional deformations of construction bases will depend on the quality of the sand mattress and first of all on the level of its compacting [5,6].…”
