DEFLECTION MEASURING APPARATUS OF PAVED ROAD SURFACE, AND DEFLECTION MEASURING METHOD OF PAVED ROAD SURFACE
PROBLEM TO BE SOLVED: To provide a deflection measuring apparatus of a paved road surface and a deflection measuring method of the paved road surface for accurately grasping the state of the paved road surface.SOLUTION: A first displacement measuring unit 20 measures the displacement of a road surface 6 when a load is charged, a second displacement measuring unit 30 measures the displacement of the road surface 6 when no load is charged, and the deflection amount of the road surface 6 is calculated on the basis of the difference between the measured values by the first displacement measuring unit 20 and second displacement measuring unit 30. First correcting means calculates an actual load acting on the road surface 6 on the basis of the strain of a leaf spring of a vehicle, and multiplies the deflection amount of the road surface 6 by a numerical value obtained by dividing a reference load by the actual load, thereby calculating the deflection amount after the correction.SELECTED DRAWING: Figure 1
【課題】舗装路面の状態を正確に把握する舗装路面のたわみ測定装置及び舗装路面のたわみ測定方法を提供する。【解決手段】第１の変位測定部２０が加荷重時の路面６の変位を測定し、第２の変位測定部３０が非荷重時の路面６の変位を測定し、第１の変位測定部２０及び第２の変位測定部３０の測定値の差から路面６のたわみ量を算出する。第１の補正手段は、車両の板バネのひずみから路面６に作用する実荷重を演算し、実荷重で基準荷重を除した数値を路面６のたわみ量に乗じて、補正後のたわみ量を演算する。【選択図】図１
