Properties of Composite Materials for Use in Expedient Paving Systems.

Abstract

Uniaxial flexure and tension tests and biaxial flexure tests are performed on two systems of fiberglass reinforced polyester (FRP) and on a FRP-polyurethane foam composite to evaluate their suitability for possible use as paving materials. Principal parameters studied are ultimate strength, fatigue performance, and modulus of elasticity. Uniaxial test results compare favorably with those from biaxial tests. A METHOD FOR STRESS ANALYSIS FOR THE BIAXIAL TESTS IS DEVELOPED TO ACCOMMODATE A CENTER LOADED, CLAMPED, CIRCULAR PLATE SUBJECTED TO LARGE DEFLECTIONS AND HAVING RADIAL FORCES ON THE BOUNDARY. Results show that factors affecting the volume proportions of resin, glass, and iar, and factors affecting the properties of the resin could have a significant influence on the properties of the FRP. Both utlimate strength test results and fatigue test results indicate that FRP/ Fiberglass is superior. (Author, modified-PL)
