EXPERIMENTAL EVALUATION OF DEPENDENCE OF PAVEMENT CHARACTERISTICS IN QUARRIES ON COMPACTION OF ROADS WITH OPEN PIT DUMP TRUCKS
The article contains the technology of pavement layer compaction in quarries, significantly improving performance characteristics of such pavements. It describes the experience of road construction in a quarry of OJSC Uralasbest and implementation results of the proposed technology. The author made an evaluation of transport and operational properties of the pavement on an experimental site constructed by compacting the road pavement with open pit dump trucks, which are available at the mining enterprise, without distracting them from their operation related to transportation of rock mass. There were found the regularities allowing for determination of the necessary number of dump truck passes to achieve a required degree of pavement compaction. The proposed technology of compaction and the resulting dependences can be used at mining plants using dump trucks, to improve technical and economic performance of open pit vehicles.
