Geotechnical Aspects for Roads on Expansive Soils

This paper presents some issues of geotechnical investigation for roads built on expansive soils. The aim of the study is to provide road engineers with guidance on site investigation; field and laboratory identification of expansive soils. A clear understanding of the expansive subgrade soils behavior and their geotechnical characteristics has been of more interest to the study in order to

Construction Problems of Light Structures Founded on

expansive soils with emphasis on design criteria and construction precautions for structures founded on expansive soils. Some cases of existing light buildings and roads in different regions in Sudan, suffered from severe distresses and damages due to expansive soils, were studied. EXPANSIVE SOILSPROBLEMS AND REMEDIES1.1 Expansive Soils and Problems Expansive soils pose problems to civil engineers in general and to geotechnical engineers in particular (Chen 1988). They cause damage to structures founded in them because of their potential to react to changes in moisture regime. They undergo severe volume changes corresponding to changes in moisture content.

GEOTECHNICAL INVESTIGATION MONTEREY-SALINAS

The primary geotechnical considerations at this site are the presence of moderately expansive near surface soils on portions of the site, collapse potential of saturated on-site soils used as engineered fill, erosion of cut and fill slopes, low subgrade support strength of on-site soils in the Geotechnical Aspects of Buildings on Expansive Soils in The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures.

Geotechnical Issues of Road Construction & On Site

This is the reference manual for FHWA NHI's Course #132040 Geotechnical Aspects of Pavements. Many groups within an agency are involved with different aspects of definition, for paved and unpaved roads with emphasis on the current AASHTO, 1993 design guidelines, and These include expansive soils, frost susceptible materials Geotechnical Aspects for Roads on Expansive Soilswhen the moisture in the soil changes. Expansive soils prevail over a large area of Sudan and have caused significant damages to irrigation systems, water lines, sewer lines, buildings, roads and other structures located on these soils. The Damage caused by expansive soils was estimated by Charlie et al [1] to exceed $6,000,000
