Large Diameter Triaxial Tests on Geosynthetic-Reinforced Granular Subbases
Journal of Materials in Civil Engineering, 2015The estimation of strength and stiffness of reinforced aggregates is very important for the design and construction of reinforced unpaved/paved road sections. This paper presents the experimental results from static and cyclic triaxial tests carried out on granular subbase samples reinforced with multiple layers of geogrid reinforcement.

Effect of Granular Subbase Thickness on Airfield Pavement Structural Response
Journal of Materials in Civil Engineering, 2008The effects of variable granular subbase thickness on the structural responses of flexible airport pavement test sections subjected to six-wheel and four-wheel multiple-wheel heavy aircraft gear loading are discussed. Four low-strength subgrade flexible pavement sections at the National Airport Pavement Test Facility (NAPTF) with different subbase ...

Transportation Research Record: Journal of the Transportation Research Board, 2022
Subbase layers under concrete pavements play several functional roles in providing a uniform support, minimizing pumping potential, facilitating drainage, and minimizing adverse effects of erodible and problematic subgrade soils. This paper presents a design alternative for a daylighted granular subbase that provides uniformity, drainability, stability,

Analysis of Granular Base/Subbase in Airport Pavements Using Embedded Sensors
This project investigates the modulus and deformation behavior of granular base/subbase layers in airport pavements using three types of embedded sensors: bender element (BE) field sensors, coil sensors, and pressure cells. These sensors were installed in multiple test items at the Federal Aviation Administration’s Construction Cycle 9 (CC9) of the ...Tutumluer, Erol +3 more

High quality aggregate materials are becoming increasingly scarce and expensive, and therefore optimizing the use of locally available materials is becoming an economic necessity. The research study highlighted in this paper aimed at optimizing the use of varying qualities of aggregate base/granular subbase materials found in Minnesota for achieving ...

Traffic and Transportation Studies 2010, 2010
In present scenario, non-availability of the conventional materials for construction of subbase of flexible pavement in many places in India has become one of the greatest problems for constructors due to variety of reasons. This problem may be overcome by decreasing the thickness of the sub-base layer by improving their strength, which ultimately ...
