1. General description:
Title:
Improving the durability of asphalt pavement on bridges by using 
polymer modifiers
Abstract:
University experts (Kyiv), specialized in mechanics of road construction 
materials and road pavements, developed practical recommendations to 
improve the durability of asphalt pavement on bridges by using polymer 
additives. They are designed for road construction industry dealing 
with the design and asphalt paving. The authors are seeking for partners 
for investment and joint implementation of this technology.
The description of the proposal:
Premature failure of asphalt pavement on bridges is due to cracking and 
landslides. The research is aimed at solving a practical problem, namely 
lack of durability of asphalt pavement caused by cracks and landslides. 
The project is intended to investigate the temperature regime of asphalt 
pavement in the current climate. It also provides for using the main 
provisions of the theory of thermo-visco-elasticity and kinetic theory 
of solids to determine the stress-strain state of the pavement and to 
develop limit state criteria. Theoretical and experimental methods were 
used in the study. The research established the impact of climate 
parameters, vehicle parameters, load time parameters, technological 
parameters on crack formation. The adhesion between asphalt and 
cement-concrete base as well as rutting were experimentally verified. 
Based on the research practical recommendations to improve the 
durability of asphalt pavement on bridges were developed. The 
researcher has been experienced in the field of quality control, 
technology of road construction materials and pavement structures 
(there are more than 15 Ukrainian patents and certificates).
Innovative aspects and benefits:
Much research of foreign and national scientists has been done on 
improving the durability of asphalt pavement on bridges. This issue, 
however, was considered separately without a comprehensive solution 
of the problem of insufficient durability of asphalt pavement due 
to the simultaneous increase of its crack and rutting resistance. 
So, crack resistance of asphalt pavement was mostly studied 
separately from traffic impact and from the effects of temperature 
fluctuations. Rutting resistance of asphalt pavement was in many 
cases practically investigated, dealing with the "conflict" ways to 
improve crack and rutting resistance of asphalt pavement. In 
addition, the results of existing studies do not reflect the 
peculiarities of climate change in recent years. The increased 
size and intensity of the traffic load on bridges as well as load 
variations (speed, acceleration when changing speed, time of traffic 
load, etc.) are not included in the studies as well. The implementation 
of this project will help increase the durability of asphalt pavement 
on bridges. Thus, it will provide the necessary service life, reduce 
repairs and, consequently, reduce the cost of material and energy 
resources for repair and maintenance of roads.
