Fracture Tests for Bituminous-Aggregate Mixtures: Laboratory and Field Investigations
… techniques. Single-edge notched beam (SE(B)) and disk-shaped compact tension (DC(T)) test geometries were developed to estimate the fracture energy of asphalt concrete. Fracture energy can be measured from these laboratory tests with adequate accuracy, which allows for the application of numerical …

Fracture of Asphalt Concrete: A Cohesive Zone Modeling Approach Considering Viscoelastic Effects
… three-dimensional mode I fracture tests, e.g. disk-shaped compact tension (DC(T)), are performed considering viscoelastic effects. The ability to simulate mixed-mode fracture and crack competition phenomenon is demonstrated in conjunction with single-edge notched beam (SE(B)) test simulation. …

Investigation of Toughening Mechanisms in the Fracture of Asphalt Concrete Using the Clustered Discrete Element Method
… is applied into mode I fracture tests, e.g. disk-shaped compact tension (DC(T)) and single-edge notched beam (SE(B)) tests, to investigate various fracture mechanisms of asphalt concrete. The simulation results are shown to compare favorably with experimental results, and moreover, the …

Development of an alternative test to obtain asphalt mixture creep compliance at low temperatures
The Disk shaped compact tension [DC(T)] test and the Indirect Tensile [IDT] creep compliance tests are widely used in the pavement materials community to characterize the low temperature fracture and creep properties of asphalt materials. The information from these tests enables pavement engineers …

Fatigue-fracture relation on asphalt concrete mixtures
… known as the plateau value (PV). Similarly, a disk-shaped compact tension DC(T) fracture test was used to obtain fracture energy parameters, including: fracture strength, pre-peak fracture energy, post-peak fracture energy, and total fracture energy. A factorial of the eight possible …

Experimental evaluation of monotonic and cyclic fracture behavior using disk-shaped compact tension test and released energy approach
… under monotonic and cyclic loading using the disk-shaped compact tension (DC(T)) test and a released-energy based approach. The standard DC(T) test was revised to facilitate both monotonic and cyclic loading tests, including some modifications of the test geometry and testing modes. The …

Performance analysis of asphalt mixtures modified with ground tire rubber and recycled materials
… ABR). A suite of tests was conducted on plant-compacted gyratories and field cores, namely, Disk-Shaped Compact Tension (DC(T)) test, DC(T) Creep Compliance test, Acoustic Emission (AE) test, and Hamburg Wheel Tracking Test. Further, DC(T)-Hamburg results were plotted on Performance-Space …

Quantitative evaluation of low-temperature performance of sustainable asphalt mixtures and binders containing recycled asphalt shingles (RAS) and rejuvenators
… HMA pavement applications was investigated via Disk-shaped Compact Tension (DC(T)) mixture testing and an acoustic emission (AE) based technique for estimating the embrittlement temperature of RAS-modified mixtures and asphalt binders prepared in the laboratory. During AE testing, the AE …

Effects of asphalt rejuvenator on thermal and mechanical properties of oxidized hot mixed asphalt
… and mechanical properties was investigated via Disk-shaped Compact Tension (DC(T)) testing and acoustic emission (AE) testing for determining the embrittlement temperature of the mixtures. During the DC(T) testing the fracture energies and peak loads were used to measure the resistance of the …
