“…Current research has mainly evaluated the failure strength of asphalt mixture through laboratory tests, such as the uniaxial compression test, direct tensile test, semi-circular bending test, etc. [14][15][16]. Qin et al [17] found that the dynamic modulus curve under indirect tension was lower than that under uniaxial tension, which depends on temperature and loading frequency.…”

Coarse aggregate is the major part of asphalt mixture, and plays an essential role in mechanical performance of pavement structure. However, the use of poor-quality coarse recycled aggregate (CRA) reduces the strength and stability of the aggregate skeleton. It is a challenge to predict accurately the influence of CRA on the performance of asphalt mixture. In this study, both a uniaxial compression test and a direct tensile test were carried out to evaluate the failure strength of asphalt concrete with four CRA content. The discrete element method (DEM) was applied to simulate the specimen of asphalt concrete considering the distribution and properties of CRA. The results showed that temperature and loading rate have a significant influence on failure strength, especially when the CRA content was more than 20%. With the increase of CRA content, both cohesion force and internal friction angle were gradually weakened. The proposed model can be used to predict the failure strength of asphalt mixture, since both experimental and simulated results had a high consistency and repeatability. With the decrease of CRA strength, the nominal cohesion force of the specimen decreased, while the internal friction angle increased.

For several years the crack propagation test data of bituminous mixtures according to CSN EN 12697-44 have been collected and evaluated at CTU in Prague. Over time the standardized test procedure was adapted to the conditions more suitable to be used in the Czech Republic-in terms of test specimen compaction, availability of cutting discs of suitable thickness, diameter of test specimens, loading speed etc. Some of the other conditions of the test were adapted as well as the procedures of data logging and subsequent evaluation of raw data. Over the years it has been identified that the strict focus only on fracture toughness is probably not correct or at least not sufficiently effective. The characteristics of fracture energy have been introduced and further studied. This paper compares the fracture toughness and fracture energy characteristics of selected sets of various types of asphalt mixtures.
