European Research into Granular Material for Pavement Bases and Subbases
Transportation Research Record: Journal of the Transportation Research Board, 2000Two transnational European research projects in the area of granular materials for road pavements are described. The results are used to illustrate the state of practice as compared to the state of the art and are placed within the setting of a broad picture of national research within Europe.

Frost Susceptibility of Granular Subbase Materials Contaminated by Deicing Chemicals
ISCORD 2013, 2013The increase in urban population in arctic areas leads to an increased demand for transportation infrastructures, such as roads and airfields, in the regions. This challenges the road constructions in terms of condition, bearing capacity and maintenance.

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 ...

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,

Transportation Research Record: Journal of the Transportation Research Board, 2012
Aggregate gradation effects on strength and modulus characteristics of aggregate base–granular subbase materials used in Minnesota are described. The importance of specifying proper aggregate grading or particle size distribution has long been recognized for achieving satisfactory performance in pavement applications.

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
