Estimation of Subgrade Resilient Modulus Using the Unconfined Compression Test
To facilitate pavement design, the new proposed mechanistic-empirical pavement design guide recommends the resilient modulus to characterize subgrade soil and its use for calculating pavement responses attributable to traffic and environmental loading. Although resilient modulus values could be determined through laboratory testing of actual subgrade soil samples, such testing would require sig...
متن کاملEstimation of Subgrade Resilient Modulus Using Unconfined Compression Test
1 2 Resilient modulus test is the recommended test to characterize subgrade soil for 3 pavement design in 1993 AASHTO pavement design guide as well as new proposed 4 Mechanistic-Empirical Pavement Design Guide (MEPDG). This test requires significant 5 resources including high level of technical capability to conduct. For smaller projects where 6 costly and complex resilient modulus testing is n...
متن کاملNumerical Investigation of Subgrade Reaction Coefficient in Sand Soils of Bandar Abbas City
The soil-foundation interaction is one of the most important issues in geotechnical engineering that deals with studying the soil behavior subjected to the side loading. Winkler’s model is the first and simplest method for consideration of the soil-foundation interaction. It is vitally important to determine the coefficient of subgrade reaction of the soil. Since several methods have been prov...
متن کاملModelling Sand Wave Variation
In this chapter we present a detailed comparison between the Golden Gate sand wave field and the results of the non-linear sand wave model. As the Golden Gate sand waves show large variation in their characteristics and in their environmental physics, this area gives us the opportunity to study sand wave variation between locations, within one well measured, large area. The nonlinear model used...
متن کاملEvaluation of Resilient Modulus of Subgrade and Base Materials in Indiana and Its Implementation in MEPDG
In order to implement MEPDG hierarchical inputs for unbound and subgrade soil, a database containing subgrade M R , index properties, standard proctor, and laboratory M R for 140 undisturbed roadbed soil samples from six different districts in Indiana was created. The M R data were categorized in accordance with the AASHTO soil classifications and divided into several groups. Based on each grou...
