Introduction. The introduction to the paper emphasizes the performance of pavements for the traffic areas of channelized/maneuvering traffic zones and heavy vehicles parking lots and highlights the advantages of concrete pavements for the said objects.
Problem statement. The issues of the paper concern the design of various types of concrete pavements for the traffic areas of channelized/maneuvering traffic zones and heavy vehicles parking lots.
Purpose. The goal of the paper is to compare the main provisions of the designated concrete pavements design in terms of various types of the monolithic pavement concrete slabs, and usage of types of concrete which differ in their laydown methods, and also regarding various principles of joints construction with an accent made on the contraction joints.
Results. The main principles of the said concrete pavements designing were reviewed through separation the input design data such as the geotechnical information, the parameters of loading, the pavement service life and the characteristics of the material. The pavement design regarding the requirements for the subgrade/subbase parameters was analyzed more detailed concerning the appointment of the pavement layers thicknesses to reach the required bearing capacity in terms of a modulus of subgrade reaction.
An analysis of the general provisions of the design of the heavy vehicles parking lots concrete pavement was performed concerning the usage of internally compacted common concrete to be cast as a monolithic pavement with the reinforced or unreinforced slabs. Peculiar attention was paid to the designing of the non-doweled jointed monolithic pavements with describing the categorization of the said objects by the intensity of the heavy vehicles traffic.
Also the clauses regarding the design of concrete pavements for the traffic areas of channelized/maneuvering traffic zones and heavy vehicles parking lots from roller-compacted concrete were analyzed, where the pavement thickness should be determined via the nomograph taking into account the values of the tire contact area, the modulus of subgrade reaction and the allowable stress of a pavement recognizing the concrete fatigue behavior; the acceptability of the design of a monolithic pavement with non-doweled joints when roller-compacted concrete is to be used was analyzed.
Conclusions. It was concluded that concrete pavements of channelized/maneuvering traffic zones, as well as parking lots of heavy vehicles perform under loading mainly on the middle part of the slab pavement, which ensures the fulfillment of the "edge support" condition “a priori”, thus the design of the pavements of the said objects differs from the design procedure for rigid road pavements.
Jointing of concrete pavements for the traffic areas of channelized/maneuvering traffic zones and heavy vehicles parking lots is affected to some extent by the type of concrete regarding its laydown method but for roller-compacted concrete pavements the design accepting the naturally occurring cracking may be advised as more economically valuable one.
The development of relevant design procedures in Ukraine will allow to expand the usage of cost-effective technologies of roller-compacted concrete, which require significantly less time and technical resources compared to technologies of concrete compacted by internal vibration.
