This research addresses the issue of designing a street in Jenin, which is Sanour- Maythaloon Street, using the 1993 AASHTO method. The purpose is to propose a solution for the defects that exist in this street which affect the performance of the pavement so that the street offers more serviceability and experiences fewer accidents.
The methodology that was adopted combined between field investigation and theoretical work. Field investigation included gathering data about traffic volume and geotechnical soil reports. In addition, several photos were taken to document the distresses in the street, and then the studied area was divided into four sections .
An earth road is one whose foundation and wearing surface is composed of solely of the natural soil present originally on the site. Soils can be classified into two categories – cohesion less and cohesive soils. It has been observed that regions that are predominantly clayey do not usually have sandy materials.Clays must be considered as very important and often determining soil component since it has two objectionable qualities that make it the most troublesome of the materials to be dealt with. It swells when subjected to wetting, and shrinks with drying.
A stabilized material may be considered as a combination of binder-soil and aggregates preferably obtained at or near the site of stabilization, and compacted so that it will remain in its compacted state without detrimental change in shape or volume under the force of traffic and exposure of weather. Several materials have been used as soil stabilizing agents. Of these, the best stabilizer will be the one involving minimum cost and at the same time providing durable effect. The technique is mainly applied in Road construction soil, and is termed as Mechanical Stabilization or Granular Stabilization.
