Characterization, Parameters, and Correlation of Highway Pavement Construction Materials

Abstract

These thesis studies highway pavement materials, types, flexible and rigid, characteristics and all tests related CBR, resilient modulus, modulus of sub grade reaction (k), design parameters, and correlation. The thesis includes study case for two roads, El Moneera – El Saffaya highway (Road 1) a national road way that made for the people who were affected by Alsteit, Atabara dams and section of Omdurman Ring Road (Road 2), samples were taken and tests were carried out to study soil type and properties of each to find out where its suitable for pavement construction or not. Test results showed that (Road 1) soil is classified as black cotton soil; this type of soil is not suitable for pavement construction and needs improvement either by usingstabilizers or soil replacement. Road 2 soil varies from sandy, silty and rocky soils. Initial test results show that it’s suitable for pavement construction after improving by compaction.
