Selection of the Optimal Grain-size Distribution of Crushed Stone Sand and Gravel Sand Mixtures for the Pavement of Truck Haul Roads of Coal Open Pits
The constant increase in traffic load at mining enterprises forces to look for ways to improve the quality of feeder roads of coal open pits. There is a constant search for tools and methods for improving road pave- ment to increase the service life of truck haul roads. It is known that haul roads are topped mostly with lightweight flexible pavements due to the pe- culiarities of moving vehicles. One of the most applicable materials for pav- ing truck haul roads is crushed stone sand mixtures. However, the lack of scientific research aimed at finding ways to improve the riding quality of open pit haul roads and increase the efficiency of open-pit truck haulage op- eration due to the roads as component of a system did not allow the use of dense-graded mixtures as a pavement for open pit haul roads. In this work, studies were carried out to optimize the grain-size distribution of crushed stone sand mixtures taking into account the physical and mechanical, strength, and deformation properties of the material.
