| Research Abstract |
Few attention is payd in construction control for gaps on pavements that become barriers for the social weak who need a wheelchair, such as a handicapped, an advanced aged or a blind person. The investigators tried experimentally clarifying the relationships between the magnitude of gaps on the surface of pavements and traveling resistance of wheelchairs, and developing standards for pavement control being suitable for the social weak.
Traveling tests of a wheelchair were conducted under various pavements conditions, and traction resistance of the wheelchair and vibration on the seat of the wheelchair were measured. The following results were drawn from the traveling tests.
1.A group of advaced aged persons of average age of 82.1 years old and average weight of 44.7 kgf can mobilize driving forces ranging from 3.6kgf to 7.3kgf. The magnitude of a gap associating with the driving forces were 1.8mm and 3.6mm, respectively.
2.The magnitude of gaps should be remained within 4 mm, in order to satisfy Canadian standard (CSA).
3.The limit gradients of approaching were 11% for distance of 40cm and 24% for distance of 40cm.
