 PATH  OF LIFE

He was born in 1936 in the Poltava region. In 1961 he graduated from the Faculty of Road Construction of the Kyiv Automobile and Road Institute. After graduation he worked at the design institute as an engineer.

      From 1962 he worked at our institute as an Engineer, Junior Researcher, Researcher and Head of Department. In 1967 he defended his thesis and received the title of PhD.

 WORKING PATH

From 1969 to 1997 he was the Head of the Department of Organic Binders. The scientific activity of the department under his leadership was aimed at improving the properties of traditional organic binders (bitumen, tar) and the development of new types of binders.

Under his leadership, the institute developed and implemented a fundamentally new technology for producing bitumen emulsions by chemical emulsification. A new method of emulsification is a special kind of processes of self (spontaneous) emulsification, associated with the chemical reactions at the interface of bitumen - an aqueous solution of alkali or acid. A distinctive feature of this technology is the formation of an emulsifier in situ (in the system itself), which allowed by such chemical reaction of small formation, grinding bitumen into drops of about 1 μm. In order to make full use of the chemical activity of the reaction, it is necessary to create optimal conditions for its occurrence.

It is these conditions Kuchma M.I. was able to develop by specially designed and very simple device, which was introduced into further production. In almost all regions of Ukraine there were installations for the production of bitumen emulsions which were used to perform various types of work in the construction and repair of road pavement. In terms of their use, Ukrainian road workers occupied leading positions in the former Soviet Union. To implement the method of chemical emulsification of bitumen, special cationic emulsifiers, which were synthesized in the department and called carboxylamines were required. Carboxylamines could also be used as effective adhesive additives to improve the adhesion of bitumen to stone material.

 SCIENTIFIC INTERESTS

Scientific development, which is directly involved Kuchma M.I. became a technology for the production of surfactants of the cationic type, which at one time significantly affected the technical progress in the road sector, and later received a new impetus in the development and production of domestic emulsifier “Desetam” and adhesive additive UDOM-1 and UDOM-2, the release of which allowed abandoning much more expensive imported.

 PATH OF LIFE

He was born in Kyiv in 1913.

There is not much information about his life, but it is known that before the Great Patriotic War he graduated from the Kyiv Civil Engineering Institute, and after his graduation he worked as an Engineer in the bridge industry.

An important scientific direction of work of Mykhailo Mishchenko is the study of the issue of using burnt and dump coal mine waste  for the construction of the subgrade. A number of normative documents in this direction have been developed.

In the 80s Mykhailo Mishchenko  actively worked on the use of blast furnace and metallurgical slag in general to stabilize the soils. Some of them turned out to be good binders, such as ground blast furnace and granular blast furnace slag. It was determined that they can be used not only to stabilize the soil, but also as a good "semi-finished product" in the production of cement. This was the impetus for the study of other industrial wastes and by-products. He later studied the scientific issues associated with the study of the stability of the road subgrade of motor roads.

Much attention was paid to mine burnt rocks. It was determined that the use of these materials is possible primarily for the construction of the subgrade. But the main drawback was identified - potential subsidence. It was Mykhailo  Mishchenko who  proposed to create a strong structure (without subsidence) by adding the  fine-grained waste from concentrators to the mine dump rocks. As a result of these researches the classification of mine dump rocks and recommendations on the  construction of highways from waste of coal mining and coal-concentration was developed. At the same time, scientific work was carried out in the direction of using  mine dump rocks as a component in the strengthening of various mineral mixtures with cement or lime. As a result, the documents were developed for the production of binders based on the use of burnt waste heaps and their scope.
Mykhailo  Mishchenko  is the author of more than 40 articles and he has developed 6 inventions recorded by the copyright certificate.

He died on August 28, 2008.

WORKING PATH

After graduating from the postgraduate studies, he began his career at our Institute as a Researcher in the Soil and Subgrade Department.

Since 2008, he headed the Laboratory of soil and subgrade of the Department of Technical Diagnostics of Structures.

SCIENTIFIC INTERESTS

     Since 1974, at the initiative of Anatolii Lytvynenko, the study of the subgrade, as a structure that must have a certain strength and stability, was developed. In contrast to previous scientific studies in this direction, where laboratory studies of soils and binders in interaction with soils prevailed, the problem of investigating the structure and actual condition of the subgrade began to be solved by using the method of dynamic soil probing under the guidance of Anatolii Lytvynenko .

     The improvement of dynamic soil probing method allowed to obtain more detailed engineering and geological sections and to show the organic connection between the method of statistical and dynamic probing, and the development of equipment allowed working in hard-to-reach places such as steep slopes and gradients, weak foundations and the like.

     In the 80-s, Anatolii  Lytvynenko  carried out the passportization of high embankments and deep cuts on the roads of Ukraine and their cadastre was compiled. On the basis of retrospective analysis of such weather and climatic indicators as monthly rainfall amount and monthly average air temperature for the period of 1812-2005, the temporal cyclicality of weather and climatic conditions of Ukraine was defined and the method of forecasting the landslides activation and other dangerous natural phenomena in time for the perspective up to 12 years was developed.

     Since 2000, Anatolii  Lytvynenko has been carrying out the research on the reconstruction of road pavements by grinding the material of the existing road surface with recycler and strengthening the obtained mixtures with cement, foamed with bitumen or stabilizers of road masses.

     He is the author of 37 scientific articles. And now he regularly publishes his papers in various road publications, including the Collection of scientific papers "Dorogi i Mosti" which is issued by our Institute.

WORKING PATH

In 1971 she started her career at our Institute as the Head of the laboratory.

In 1976 Liubov Kyrychenko obtained the academic title of Senior Researcher.

SCIENTIFIC INTERESTS

Liubov Kyrychenko’s scientific activity was directed to improving of traditional organic binder’s properties and the creation of new types of binders, the development of new resource- and environmentally friendly technologies.

Liubov Kyrychenko together with Mykhailo Kuchma took an active part in the study of emulsions and the development of new emulsification technologies, new compositions of emulsions and non-traditional at that time methods of their application. It should be noted that in the 70's, there were 24 emulsion bases operated in the roads facilities industry, which produced about 50 thousand tons of bitumen emulsions. The conversion of existing bitumen bases to chemical emulsification technologies has reduced the energy costs for the manufacture of emulsions in many times.

Implementation of the bitumen chemical emulsification method required specialized cationic emulsifiers which were synthesized in the Department and were called carboxyl amines. They could be used as effective adhesives to improve the adhesion of bitumen and stone materials.

In 1974, with the participation of Liubov Kyrychenko, the compositions, technology for preparation and laying of cationic slags (known as “Slurry Seal” technology) were developed using cationic bitumen emulsions on carboxyl amines and phthalic acid amino-polyester specially synthesized for this decomposition retarder. Further wide use of emulsions was hindered by the lack of industrial synthesis of carboxylamine.

Liubov Kyrychenko participated in the development of technology for use of the rubber industry products, such as rubber crumb.

In the 2000’s L Kyrychenko investigated the effectiveness of the adhesive additive of UDOM series (cationic surfactants), polymer modifier of "Polydom" bitumen , “Desetam”  emulsifier for different types of emulsions.

Also Liubov Kyrychenko is the author of more than 90 scientific and research papers and more than 30 articles, has 5 copyright certificates.

Leonid Tarasenko was born on August 4, 1926 (Donetsk region).

In 1952 he graduated from the mechanical faculty of the Automobile Road Institute and obtained “Mechanical Engineer” specialty. After graduation he started his career at the enterprises of the road industry: “Yuzhvodstroy” Trust (1952-1956), Department of Transport of the Ministry of Coal Industry (1856-1957), Sovnarkhoz Transport Department (1958-1962), Regional Production Directorate of Construction and Operation of Roads (1986-1972)

In 1972 he defended his dissertation at the post-graduate courses of Kharkiv Automobile Road Institute and obtained the PhD degree.

WORKING PATH

In 1986 he was appointed on the position of the Director of our Institute, where he worked till 1994.

Leonid Tarasenko’s scientific activity, during the period of work in our Institute was devoted to the problems of reclaiming of aged asphalt concrete.

SCIENTIFIC INTERESTS

Leonid Tarasenko was a co-author of scientific and technical developments, recommendations, methods, technologies for working with aged asphalt concrete. The results of the researches allowed to perform work on the loosening and grinding of the upper layers of aged asphalt concrete pavement, generally, in a highly mechanized way. One of them, so-called "cold" method, was carried out on the basis of existing road construction machines with the subsequent transportation of asphalt scrap to the plants for recycling of aged asphalt concrete (when the whole process of loosening and grinding is performed at the ambient temperature).

Another “hot” method involves the thermal heating, milling of heated layers and transportation of asphalt scrap to recycling plants with its subsequent use as for the arrangement of foundations or roadsides, also as an active additive to the standard asphalt concrete, which is prepared again. But the main attention of Leonid Tarasenko, as a scientist, was directed to the method of thermal profiling, when there is a need to repair roads due to deformation of the upper layers of asphalt concrete pavements in the form of ruts, sagging, displacements, shallow pits, cracks, etc. The task was to reach the evenness of pavement without a significant increase of the solidity of pavement design. Thermal profiling method created the possibility to solve these types of repairs by thermomechanical way with hot reshaping of the repaired layer of asphalt concrete directly in the road pavement. He made a great contribution to the development and improvement of roads in Donbas and contributed to the rise of scientific and technical development of the road industry.

Awards: Order of Lenin (1971), Order of the Red Banner of Labor (1981), Order of “Badge of Honor”, “Honored Builder of Ukraine” title.

In 1988 he defended his dissertation “Research of the processes of heating and distribution of binders in mobile machine for road construction works” and obtained the PhD title.

It should be noted that in the 60's it was created a set of machines that allowed to mechanize completely the technological process of construction of structural layers of roads. A big role in this was played by the staff of the institute and personally O.I Makarchuk.

-SCIENTIFIC INTERESTS-

With his direct involvement in the 80's scientific developments were performed regarding creation, improvement and modernization of road machines:

-    for winter maintenance (rotary snowplow, combined machine for winter maintenance) and summer maintenance of roads (combined machine for patchworks),

-    to rehabilitation of the roadway ,

-    for transportation and distribution of black binders, stone materials,

-    for consolidation of constructive layers of roads.
Some of them were unique and it was a scientific and technological breakthrough in the industry.

      In order to save scarce repair materials were created the following:

-    trailer sectional heater for heating of coverings at their pit repair;

-    a machine for current repair of coatings, which mechanized its process with the presence of additional equipment;

-    a set of machines for the restoration of asphalt-concrete pavement by thermal profiling.

-WORKING PATH-

He started working at our institute in 1981 as the Head of Artificial Structures Department.

He was directly involved in the development of U-shaped girders of 12 and 18 meters long. The girders were adapted to the conditions of manufacturing in the existing hollow-core slab stands These girders eliminated the problem of voids formation and problem of splines, which were replaced by hinged joints. But these girders could not solve the main problem - increasing the length of bridge spans. The Artificial Structures Department headed by Petro Kovalev presented the initiative to create prefabricated girders with a length of 24 m, which in compare with the unified girders were 1.5 times lighter in weight and involved the use of stressed reinforcing bars of AIIIв class. The use of these structures started in the late 80's, including on the road Kyiv-Odesa.

-SCIENTIFIC INTERESTS-

In 90’s the developments of Petro Kovalev and his Department were concentrated on increasing of operational performance of existing bridge structures, prolongation of their service life. Much attention was paid to the development of methods of bridges repairing, in particular to the issues of  a reliable bridge deck arrangement. Proposals for bridges overlapping with monolithic slabs were developed; prefabricated monolithic spans on the basis of using unified beams were investigated; The design of a fundamentally new series of span structures made of stressed span elements (SSE) overlapped by a monolithic overhead slab were developed. 

For the development of the design of the experimental continuous box bridge span structure he was awarded a bronze medal of the VDNKh (Exhibition of Economic Achievements) of the Ukrainian SSR.
