However, no statewide average MR values or correlations are currently available for coarse-grained soils (A-1, A-2 and A-3). Although some actual measured values are available, it has also been noted from the data that MR of coarse-grained soil is measured significantly lower than AASHTO recommended MR values (MEPDG default) which needs to be further investigated. The objectives of the proposed project are to develop recommended MR values for local coarse-grained subgrade soils and to establish correlations (if available) with other simple conventional soil tests to estimate MR values for coarse-grained subgrade soils that can be used when necessary. The findings from this study are expected to facilitate proper pavement design for Virginia roadways and help in VDOT’s efforts in implementing MEPDG. ]]> Tue, 25 Oct 2022 09:55:46 GMT https://trid.trb.org/View/2050261 Characterizing the permanent deformation Response-Behavior of subgrade material under cyclic loading based on the shakedown theory https://trid.trb.org/View/1889672 Fri, 19 Nov 2021 15:28:13 GMT https://trid.trb.org/View/1889672 Liquid water–vapour migration tracing and characteristics of coarse-grained soil under high-speed railway train loading in cold regions https://trid.trb.org/View/1844616 Fri, 21 May 2021 10:56:59 GMT https://trid.trb.org/View/1844616 Evaluation of the Filtration Effectiveness of Dewatering Bags and Assessment of Potential Improvements https://trid.trb.org/View/1850291 Mon, 17 May 2021 14:58:50 GMT https://trid.trb.org/View/1850291 Liquid water–vapour migration tracing and characteristics of unsaturated coarse-grained soil in high-speed railway subjected to freezing and different load types https://trid.trb.org/View/1838378 Wed, 21 Apr 2021 16:17:50 GMT https://trid.trb.org/View/1838378 Experimental study on permanent deformation characteristics of coarse-grained soil under repeated dynamic loading https://trid.trb.org/View/1841060 Fri, 09 Apr 2021 17:33:55 GMT https://trid.trb.org/View/1841060 Coupling effects of particle shape and cyclic shear history on shear properties of coarse-grained soil–geogrid interface https://trid.trb.org/View/1760851 Wed, 27 Jan 2021 09:56:34 GMT https://trid.trb.org/View/1760851
