METHODS ANALYSIS FOR DETERMINING THE EFFECT OF STATIC AND DYNAMIC LOADS ON ROAD PAVEMENT

Anna Kharchenko Oleksandr Chechuga Akim Alimov

The methods based on the determination of total or elastic deformations in the evaluation of the deformation characteristics of road structures have been studied. It was determined that all methods mainly differ among themselves in the way of testing and equipment; a methodical approach to processing the received data. In particular, static methods are divided into stamping and methods of determining the static load of a car wheel. It is noted that methods based on determining the dynamic load on road pavement, which are divided into shock and vibration, are becoming more and more popular recently. The generalized sequence of performing tests using dynamic load methods is presented, which includes: determining the measurement route, moving the equipment and setting it to the i-th measurement point; preparation of the equipment for measurement: installation in the working position of extinctions; execution of tests; collection and processing of measurement results. It was determined that for effective suction of these methods, it is necessary to have historical data and spatial distribution of loads; information on the composition of the traffic flow, speed regimes on the site; geometric parameters and characteristics of the technical condition of the site; characteristics of the chosen method for measuring loads on road pavement; dynamic reactions of individual components of the road structure are determined. It is noted that the accuracy of the results of dynamic load measurements can be affected by the type of vehicle suspension, vehicle type, amount of load on the vehicle, vehicle speed, technical condition of the road surface, in particular, the unevenness of the surface and other factors. Reconciliation of the results of testing road pavement by methods of determining the action of static and dynamic load requires the use of special coefficients. Based on the results of the review of the methods, it is proposed to further investigate the factors affecting the accuracy and reliability of the data obtained by them
