Abstract
Development of compositions of bitumen-mineral open mixtures for the Novoselovsky district of the Krasnoyarsk Territory
Incoming article date: 09.01.2024This paper is aimed to present the produced compositions of bitumen- mineral open (BMO) mixtures for the Novoselovsky district of the Krasnoyarsk Territory. The Federal Road M53 runs through the area and in this district in particular it is characterized by steep ascents and descents. To ensure the required adhesion properties of road asphalt concrete pavements with car wheels for thepurpose of traffic safety in the area under study, the construction of rough wearinglayers or toppings from BMO mixtures has been suggested. Compositioncalculations were carried out using local mineral materials and BMO mixtures,after which test samples were prepared in laboratory conditions. It has beenestablished that the developed BMO mixture compositions meet all regulatory requirements. Recommendations are developed for the factory technology ofpreparing bitumen-mineral open mixtures and the design of rough wearing layers.Instructions for technical control during the preparation of BMO mixtures aregiven. The Road Repair and Construction Department of the Novoselovsky districthas already introduced the obtained compositions into the practice of road construction.
