BEHAVIOUR OF PERMEABLE ASPHALT
PAVEMENT BASED ON A SMALL-SCALE
MOVING-WHEEL LOAD TEST

Abstract
In this experimental study, a moving-wheel load test was carried out on a small-scale asphalt pavement
under four environmental conditions, (a) room temperature, (b) room temperature with pavement surface of
60C°, (c) room temperature after watering and (d) pavement surface of 60C° after watering, in order to
grasp the behavior of permeable asphalt pavement, focusing on the vertical earth pressure at the subgrade,
horizontal strain at the asphalt mixture layers and seepage water at the pavement surface. From this, the
followings can be pointed out.
- The room temperature was about 10C° and under this low temperature, permeable asphalt pavement
suffered little detrimental effects. The vertical earth pressure at the surface of sandy subgrade was small,
the horizontal tensile strain at the bottoms of porous asphalt mixture surface-course and base-course was
small and there was little rut developed. Furthermore, there was no reduction in the amount of seepage
water at the pavement surface.
- Under the condition of 60C°-surface temperature, the pavement behavior quite differed from that under
the room temperature. A large vertical earth pressure acted on the surface of sandy subgrade beneath the
center of the wheel, fading away with a horizontal distance from the center of the wheel. The vertical
earth pressure gradually increased with accumulation of wheel passages. Horizontal tensile strain was
maximum at the bottom of porous asphalt mixture base-course and next-largest at the bottom of porous
asphalt mixture surface-course; it increased with accumulation of wheel passages. The pavement surface
was rutted by about 10 mm during the test. A measurable reduction was observed in the amount of
seepage water at the rutted part of the pavement surface.
