Geotechnical Study
Geotechnical data was gathered from El Paso City office. According to the information provided, the type of soil in the zone is mostly sand. Since the information was too broad, a geotechnical study was requested from a local company. The information provided by the local company is not exactly from the project zone but it is close enough to assume that the soil is the same (Appendix A). The American Association of State Highway and Transportation Officials (ASSHTO, 1993) soil classification system was used to classify the type of soil in the area, according to that study the soil ended up
to be silty sand (SM). The geotechnical report did not shown any abnormality or problem on the soil profile, which means that there is no need for any stabilizer.
Once earthwork has been completed (see Roadway geometry) compaction needs to take place. Compaction is really important because it will improve some engineering properties. Compaction will increase shear strength which will improve the ability of the road to hold heavy loads such as the loads produced by big trucks. Moisture needs to be maintained under optimum conditions in order to achieve the maximum dry unit weight. Earthwork, moisture conditioning and compaction is going to get done using heavy equipment such as excavators, bulldozers, backhoes, water trucks, rollers among other.
