I. Granular base course
II. Bituminous binder
III. Granular sub-base cum drainage layer
IV. Prepared soil subgrade
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFFlexible pavements: Flexible pavements are so named because the total pavement structure deflects, or flexes, under loading.
Flexible pavement may be constructed in a number of layers and the top layer has to be of the best quality to sustain maximum compressive stress, in addition, to wear and tear. The lower layers will experience the lesser magnitude of stress and low-quality material can be used.
∴ The order of the components of a typical flexible pavement from bottom to top is prepared soil subgrade, Granular sub-base cum drainage layer, Granular base course, Bituminous binder, and/or surface course.Last updated on Jun 2, 2025
