EVALUATION OF THE STRENGTH MARKET OF THE FLEXIBLE PAVEMENTS, DESIGNED WITH THE APPLICATION OF THE COMPACT-ASFALT TECHNOLOGY, FROM THE TRAFFIC INTENSITY
Abstract
One of the ways to decrease expenditures while installing road surface layers is to reduce the thickness of the construction by using the "compact-asphalt" technology. In spite of the availability of publications and expert opinions about the effectiveness of the uninterrupted paving-technology asphalt mixtures without losing durability of road surface layers, regular methods of construction road surface layers do not give an opportunity to combine several layers of asphalt mixtures in process of strength calculation. The article represents the results of a mathematic experiment, which value the effect of the joint paving the lower covering layer and the upper base layer in three-layer asphalt packages on the change durability of the rode surface layers. It has shown, that in the case of using the «compact-asphalt» technology, could be achieved a certain reserve of strength, depending on the total number of rated load applications over the service life of the road surface layers. The developed approach could be included in the renewed normative documents for the flexible pavement design.
