T. Muro et Y. Hoshika, TRACTIVE PERFORMANCE AND COMPACTION EFFECT OF A ROAD ROLLER RUNNING ON A WEAK SANDY SOIL, Journal of terramechanics, 32(5), 1995, pp. 245-261
This study aims to investigate the tractive performance of a two-axle,
two-wheel vehicle with rear-wheel drive or brake and the compaction o
f a decomposed granite soil. The effects of traction or braking, the c
hange of sinkage, the slip ratio of the front and rear roller, and the
number of passes of the road roller were studied. A number of tests w
ere conducted and the experimental data were compared with the theoret
ical analysis results. It was observed that the amount of sinkage on t
he front and rear roller took the minimum value when the front roller
was in the unpowered rolling state and the slip ratio of the rear roll
er was almost zero. When the absolute value of the slip ratio of rear
roller increased, the amount of sinkage on the front and rear rollers,
the absolute value of the driven or braking force of the rear roller
and the absolute value of effective tractive or braking effort of the
road roller increased. When the front roller was in the unpowered roll
ing state and the rear roller was in the braking state at -5% skid, th
e compaction density of the soil was at a maximum. Copyright (C) 1996
