According to scientific research from different countries, crumb rubber obtained end-of-life tires (ELT) during processing can improve the properties of asphalt mixture, thereby extending service life road surface. This paper presents modification bitumen with industrial waste. The for roads is considered one most suitable and popular approaches. describes details using types as modifiers. modified bitumen’s main physical mechanical characteristics were determined after conventional tests:...
Currently, in the world, due to constant desire for recycling, many countries are considering possibility of using rubber waste on roads. Bitumen modification roads Kazakhstan is considered one most suitable and popular approaches. This article presents results research bitumen with chips obtained from waste. The document describes detail details as modifiers, particular emphasis how they can potentially be used improve performance road durability. A wet process produce rubber-bitumen...
Natural bitumen has long been used in road paving, but recent years, the demand for it decreased. However, use of natural surface is gaining popularity again. a high content asphaltenes and higher molecular weight compared to petroleum bitumen. For purpose promising application as construction materials, studies were conducted on selection compositions based oil-bitumen rocks Karasyaz-Taspas deposit.
Background: Ageing is a natural biological process, manifested in gradual decrease the adaptive capacity of organism. The causes social alienation among elderly people have multifactorial nature. Stroke very dangerous disease since it disrupts work most important organ - brain. problem stroke prevention has been particularly relevant past decade. Aims and Objectives: research was conducted to study state medical risk factors for development cardiovascular old individuals. Materials...
