Theoretical and Experimental Research Model of Junctioning Rigid and Non-Rigid Road Pavement | Chapter 12 | New Approaches in Engineering Research Vol. 14

The intersection of rigid and non-rigid road pavement portions is a source of significant load. The creation of sinking in the road surface is caused by residual strain over time. Although this is not a major flaw in the road surface, it has a detrimental impact on driving comfort. This effect is not limited to road pavement that has been damaged by overloading. The lack of verification and quality control throughout work is not thought to be a contributing factor to the problem. It is based on internal physical processes that occur at the intersection of rigid and non-rigid road pavement portions under wheel loading. The topic of this article is the problem of non-rigid road pavement subsidence at the intersection of rigid and non-rigid road pavement sections. Subsidence at the pavement's intersection occurs most frequently around bridge approaches. The formation of pits on the road can be caused by the subsidence of the non-rigid road pavement. The production of suffusion at non-rigid road pavement subsidence is caused by inconsistencies in the operation. It is vital to consider not only the amount of load from the wheel, but also the direction of impact.

The research topic is related to the construction and maintenance of roads. The causes of subsidence creation at the approach section of a non-rigid to a hard road pavement are investigated in this article. The causes of this phenomena of drawdown have not been investigated. There is no clear understanding of the nature of mold's appearance and structure at the intersection of rigid and non-rigid pavements.

The complete research of the transition from fracture to tension to fracture connected with soil stability concerns [1,2], as well as the fabrication of composite materials based on them [3,4], receives a lot of attention in the reviewed studies. The formation of sinking is established when calculating pavement based on the application of loads to the coating's surface [5,6]. When strengthening both foundation soils and coating materials to boost bearing capacity, the themes of preventing sinking are paid a lot of attention [7]. Different types of impact on structures caused by external environmental elements, such as water-thermal [8] and aggressive media [9], have been extensively researched. Many studies [10-13] have been written about the work of materials in soils under various hydraulic regimes of free water, and the calculations are done using half-space methods [14,15,16], without taking into account the crucial component of a load motion vector. Static loads were employed in the computations. The focus of research on this topic is gradually shifting away from the basic reasons of creation. It explores the method of enhancing existing materials [17-20]. This condition led an in-depth investigation of the causes of the emergence of mould on stiff and non-rigid pavements.
