Explanation / Answer

Q1

A Paving fabric interlayer is placed between the existing asphalt road and proposed asphalt overlay  as a way to strengthen the bond and to reduce reflective cracking.

Q3

Bearing capacity of soil is affected by high ground water table and due to that road pavement failure becomes a major problem in such areas. To overcome this problem,and to improve the bearing capacity of the soil the following methoda to be employed

1. the use of geogrid-  geogrid helps to increase the bearing capacity of the subgrade soil while greatly reducing the loss of the aggregate cover material into weak, wet, or saturated subgrade soils. The use of geogrids also provides, extensive cost savings and decreased life cycle costs when compared to other structural solutions

2.cement mixing,

3.proper subsurface drainage.

4.Soil can be improved by the addition of a stabilizer or excess aggregate

Q4

If the subgrade is highly plastic or weak, then stabilization may be required. The most commonly used stabilizers are cement and lime.
