By: Language: English Language: French Series: ; topicVI-105Publication details: XIth international winter road congress 2002, Sapporo [Japan] / XIe congres international de la viabilite hivernale 2002, Sapporo [Japon]. Paper, 2002Description: 10 sSubject(s): Bibl.nr: VTI 2002.0071Location: Abstract: The present paper tries to propose an optimum structure of drainage pavement for solving the problems in a snow season. Firstly, effects of maximum grain size and void ratio of materials on permeability of a pavement and the performance in a snow season were investigated in a laboratory. Next, new materials of a drainage pavement were examined. Laboratory tests were conducted by using filler containing chloride as antifreeze, and hard aggregates and rubber chips as resin mortar. Furthermore, trial drainage pavements by using general materials with different mix design and new materials mentioned above were constructed and the performance in a snow season was investigated.
