MAKARCHUK OLEKSANDR IVANOVYCH

An outstanding developer of road machines.
Created a unique set of machines to save scarce repair materials.
Developed and implemented a thermal grader to recover the design profile of asphalt pavement

-PATH OF LIFE-  

Makarchuk Olexander Ivanovych was born on November 25, 1940 in Uman.

In 1957 he entered the Uman Technical School of Agricultural Mechanization, graduating in 1960.

In 1963 he entered the Road Construction faculty of Kyiv Automobile and Road Institute and obtained a mechanical engineering degree.

-WORKING PATH-

In 1968 he started his career at our institute as engineer in complex mechanization of road construction works department. From 1971 he held the position of head of the department.

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.

For the development and introduction of a thermal grader for the rehabilitation of the design profile of asphalt pavement during the repairing of roads O.I. Makarchuk and other employees of the institute were awarded by the State Prize of the USSR in the field of science and technology (1985) The machine has been successfully tested on the roads in many areas, as well as abroad. With the help of a thermal grader, the whole process of pavement repairing by thermal profiling was completely mechanized. At least 600 tons of asphalt-concrete mixture was saved for almost 1 km of the road under repairing.

In the 90’s, the department headed by O.I. Makarchuk started analytical research and monitoring work to study the functional, technical, operational performance of road machines, machinery and equipment, the possibilities of their optimal use, taking into account the real conditions of the road industry of Ukraine (performing of maximum volumes of work with minimal costs).

O.I. Makarchuk is an author of 36 scientific articles.

-AWARDS-

Awarded by the State Prize of the USSR in the field of science and technology (1985)
