In the article, in field (on the bus lane of a city road) using modeling and traffic flow analysis methods, the rut formation on an asphalt concrete pavement is studied. The maximum total rut depth on the road section under consideration reaches 92 mm; 5% of measured rut depths exceed 35 mm; 75% of them are more than the permissible value. Almost 1100 trolleybuses and buses pass along the bus lane of the road per day, the relative rutting effect of which is from 3.04 to 6.59; their permissible number of passages ranges from 37,823 to 82,069. The pavement structure on the experimental section with a total thickness of 50 cm is too weak for the actual traffic flow, which was the main reason for the premature destruction of the road due to unacceptable track sizes on the asphalt concrete surface.

摘要

In the article, in field (on the bus lane of a city road) using modeling and traffic flow analysis methods, the rut formation on an asphalt concrete pavement is studied. The maximum total rut depth on the road section under consideration reaches 92 mm; 5% of measured rut depths exceed 35 mm; 75% of them are more than the permissible value. Almost 1100 trolleybuses and buses pass along the bus lane of the road per day, the relative rutting effect of which is from 3.04 to 6.59; their permissible number of passages ranges from 37,823 to 82,069. The pavement structure on the experimental section with a total thickness of 50 cm is too weak for the actual traffic flow, which was the main reason for the premature destruction of the road due to unacceptable track sizes on the asphalt concrete surface.
