Part 2: Evaluation of Subgrade Resilient Modulus: Resilient Modulus Estimation System for Fine-Grained Soils

, 2006
A software tool was developed to estimate the resilient modulus of fine-grained subgrade soils. The subgrade resilient modulus is a key factor for use in mechanistic-empirical pavement design methods.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Developing Correlation Relationship between Modulus of Subgrade Reaction and Resilient Modulus for Florida Subgrade Soils

, 2011
The resilient modulus of pavement subgrade is an essential parameter for mechanistically based pavement design procedures; the modulus of subgrade reaction (k) is used as a primary parameter for rigid pavement design.

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

CALCULATION METHOD OF SUBGRADE ELASTIC MODULUS FOR ASPHALT PAVEMENT USING RESILIENT MODULUS

Journal of Japan Society of Civil Engineers, Ser. E1 (Pavement Engineering), 2012
Elastic modulus of subgrade is an important input parameter in the multilayered elastic structural analysis of asphalt pavement, and the resilient modulus measurement of subgrade materials which assumed action of the vehicle load has been examined energetically after 1990's by laboratory testing.

Effect of moisture content of cohesive subgrade soil

MATEC Web of Conferences, 2018
A good subgrade for road pavement is required to support the traffic load that passes through. The characteristics of the subgrade is determined by the stress-strain behaviour that is expressed as a resilient modulus.
