Practical Aspects of the Use of Fly Ash During Cold Recycling of Road Clothing

The article examines the use of fly ash in materials produced by cold recycling technology. The ecological problem that arises during the storage of ash and slag materials has been studied. The question of the use of fly ash in road construction was considered. The composition of the mixture was selected, the consumption of materials was determined, samples were formed, which were then tested for compliance of their physical and mechanical characteristics with the requirements of national standards. After the arrangement of the experimental site, a number of field tests were conducted. Based on the results of research, it was established that fly ash mixtures meet the requirements of current regulatory documents in terms of their physical and mechanical properties and have characteristics no worse than mixtures made using the classic cold recycling technology.
