“…The pore fluid seems to influence that stage of damage, with visible differences in the propensity for abrasion in the different RUNs. In dry conditions (RUN 1 and RUN 2) the rolling and sliding between grains generate fines which could have formed a cushion (Woodside & Woodward, 1998;Lin & Lourenço, 2020), damping the impact of the steel balls between particles as shown in Figure 10a. In RUN 3, on the one hand, the viscosity of water reduces the grain dynamics during rotation (Chou et al, 2014), thus the intensity of particle interactions decreases.…”

“…They trace the reason for this phenomenon to the fact that friction between aggregate particles decreases when aggregate is saturated. A similar comparison was performed for the M DE/DS test by Strzałkowski [ 83 ] and Woodside and Woodward [ 84 ]. They demonstrated that the abrasion value of saturated aggregates is greater than the abrasion value of dry aggregates.…”

The aim of this article is to present the current knowledge and experiences related to wear and fragmentation resistance tests and to indicate those of their aspects that require further research. For this purpose, a review of the literature was performed. Results show that tests of resistance to wear (the MDE/DS test) and fragmentation (the LA test) are performed worldwide according to different standards (and thus following different test methods), which prevents a comparison of the obtained results. Comparative research into the MDE/DS and LA tests indicates that the MDE/DS test is more effective. The disadvantage of both tests lies in the dimension range of the aggregate. In addition, the use of steel balls in the LA test may not reflect the actual influence that the internal properties of the material have on the fragmentation process. A final review of the available knowledge allowed the formulation of proposals regarding further research directions, such as proposed changes of test methods, extensive analysis, and selection of optimal dimensions for tested aggregates, analysis of short-term and long-term tests, as well as extensive research into and an analysis of the impact of crushing on the physical, mechanical, and geometric properties of aggregates.

“…Test results show that, there is a rapidly decreasing in skid numbers on the test roads during the winter season. Woodside and Woodward[21] conducted on abrasion test on damp and dry aggregates and reported that damp aggregates exhibit weaker strength. Thus, in the presence of water, aggregates wear more rapidly.…”

Surfacing seal is an asphalt pavement type preferred because of its simplicity of application and economic viability. It enables waterproof surfaces for sub-layers and creates smooth and high skid resistance for vehicles. Therefore, surfacing seals constructed on unbound base are widely used such as New Zealand, Australia and South Africa. However the performance of surfacing seals can be affected by a number of factors. If these factors are not considered, they will need to be reconstructed after a very short period. In this study, performances of surfacing seals under heavy traffic were observed for 2 years, and routine tests were performed to determine the surfacing seal's performance in relation to traffic and climate and to determine the kind of deteriorations which occurred. In this study variety of test such as sand-patch, British pendulum, density measurement with electromagnetic method, measuring surface temperature with thermal camera, light weight deflectometer, dynamic cone penetration test and layer thickness measurement were performed with ground penetrating radar technique. The results of the study show that loss of macro texture, and raveling and flushing are the most common types of deterioration especially at road sections with longitudinal slope. Furthermore, skid numbers decrease during the rainy seasons when the bearing capacity of layers also decreases, the trend of raveling deterioration decreases at roads with high traffic volume and average maximum surface temperature. However, it was determined that trend of flushing deterioration increase.
