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 کاملFlexible Pavement Test Sections for Studying Pavement Design
It is a well-recognized fact that our pavement design procedures are inadequate in general and seriously lacking in many particulars. The fact that this statement can be applied on a county, state or national basis is little consolation to those in Indiana who must design and build pavements, for ever-changing traffic conditions, in such mileage and at such unit costs compared to the funds avai...
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...
متن کاملPreliminary Flexible Pavement Rehabilitation Design
The development of a knowledged-based expert system to assist ~he New Mex~co State Highway and Transportation Department m the evaluation and design of rehabilitation schemes for flexible pavements is described. The system uses information provided by users to establish preliminary rehabilitation schemes that would be reasonable and cost-effective. A cost-estimate module for ~anking th~ rehabil...
