   <abstract xml:lang="ru">
    <p>В процессе эксплуатации автомобильных дорог не всегда удается добиться требуемых характеристик грунтов, которые обеспечивают необходимую долговечность и прочность. В этой связи широкую практику получила технология укрепления грунтов известью, позволяющая значительно улучшить их характеристики. Представлены результаты экспериментальных исследований, направленные на изучение особенностей влияния извести на характеристики песка и время выдерживания грунта при оптимальной влажности в герметичных пакетах. Показано, что введение 5% извести способствует увеличению оптимальной влажности песка на 1% и обеспечивает увеличение плотности скелета грунтоизвестковой смеси на 5% по сравнению с неукрепленным грунтом. Оптимальное время выдерживания песка мелкого, укрепленного известью, достигает 2 ч. Результаты открывают широкие возможности для дальнейших исследований по укреплению грунтов в ходе дорожного строительства.</p>

    <p>It is not always possible to achieve the required characteristics of soils that would provide the necessary durability and strength during the operation of automobile roads. In this regard, the technology of soil reinforcement with lime, which allows to improve significantly the characteristics of the soil, is widely practiced. The paper presents the results of experimental studies. They are aimed at studying the peculiarities of lime impact on sand characteristics and time of soil holding at optimum humidity in sealed packages. The paper shows that the introduction of 5% lime helps to increase the optimum moisture content of sand by 1% and provides a 5% increase in the skeletal density of the soil-lime mixture compared to unstrengthened soil. The optimum curing time for fine sand strengthened with lime is 2 h. The results obtained open a wide range of possibilities for further research on soil strengthening for road construction.</p>
