Title:
ポットホールの発生を防止する方法
Document Type and Number:
Japanese Patent JP6678019
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable adequate repair work to be timely implemented by predicting generation of pot holes.SOLUTION: A drainage pavement has a pavement structure including following three layers: a base course that is a lower layer; a foundation course that is a middle layer; and a surface course that is an upper layer. On the drainage pavement, local uneven settlement of the pavement surface is considered to generate due to progressing deterioration of the foundation course and deeper courses. When the local uneven settlement reaches a predetermined settlement value, a repair plan including repair of a pavement structure of the region where the settlement value is reached is formulated and pot holes are prevented from occurring.SELECTED DRAWING: Figure 7
