ABSTRACT

This project involves the route survey which includes: reconnaissance survey, theodolite traversing and leveling operations as well as soil tests which includes; plastic limit test, liquid limit tests and moisture content determination, compaction tests and California bearing ratio tests.

This project also involves the design of the pavement and the geometric design of the roadway.
