Title: TEST PROCEDURES FOR CHARACTERIZING DYNAMIC STRESS-STRAIN PROPERTIES OF PAVEMENT MATERIALS
Accession Number: 00133990
Record Type: Monograph
Record URL: Availability: Find a library where document is available Abstract: Procedures are described for determining the dynamic modulus of elasticity by the following tests: repeated load triaxial test, complex modulus test, flexural bending test, indirect tensile test, and resonant column method. A simplified, approximate test procedure is given for determining the dynamic modulus for cohesive soils. The laboratory testing procedure, sample preparation and type of equipment for performance of the tests are described. Some of the problems involved in the dynamic testing of highway materials are defined, and procedures which minimize those problems are suggested. Data which have significant effect on pavement performance are considered. These data relate to stress pulse, dynamic moduli, Poisson's ratio, and the type of material. Specimen preparation and compaction processes for compacted cohesive specimens, compacted granular specimens, and compacted asphalt concrete beam specimens are detailed. Also described is the resilience testing of unstabilized soil which will define the resilient characteristics of untreated granular and cohesive soils for conditions that represent a reasonable simulation of in situ state of stress in pavements subjected to moving wheel loads.
