Evaluation of Troxler 3241-C nuclear asphalt content gauge used for Marshall specimens
Asphalt cement content is one of the most important requirements for producing high quality hot-mix asphalt. The determination of the asphalt cement content of hot-mix asphalt by traditional methods is time consuming and hazardous. A demand for faster and safer methodes) led to the development of a …

Effect of specimen geometry and test configuration on the fracture process zone for asphalt materials
… notch length, specimen thickness, loading rate, air void content, and asphalt binder on I-FIT global results and microstructural response. Multiple samples with varying notch lengths, thicknesses, and loading rates were evaluated to observe the effect of the test parameters. Then, samples with …

Characterization of High Porosity Drainage Layer Materials for M-E Pavement Design
… treated permeable base mixture of different air void contents has also been quantified in laboratory. Numerical simulations are conducted to investigate the location effects and the contribution of the drainage layer as a structural component within pavement. The optimal air void content of …

Laboratory evaluation of asphalt-portland cement concrete composite
… Composite (APCCC) is a hot-mix asphalt with air voids in the range of 25 to 30 percent which is later filled with resin modified cement grout. The resin modified cement grout consists of portland cement, fly ash, sand, water, and prosalvia (PL7) additive. The objective of the research was …

Hot Mix Asphalt Permeability: Tester Size Effects and Anisotropy
… and analyze. A series of samples with different air void contents were used to observe how the ratio of vertical to horizontal permeability changes with air void content. The second goal was to develop a modified field permeameter to study the water-pavement contact area effect on field …

Analysis of Fine Asphalt Concrete Mixture Gradations from Various Sources to Enhance Durability
… finer gradation asphalt mixes have lower air void content and therefore higher moisture damage resistance. This is because the finer aggregates tend to fill the voids that were otherwise not filled by the coarse aggregates. This will lead to enhanced durability because less water and air …

Digital Mix Design for Performance Optimization of Asphalt Mixture
… the determination of a gradation, asphalt content, other volumetric properties, the evaluation of mechanical properties and moisture damage potentials. In this study, a computational method is developed to aid mix design. Discrete element method (DEM) was used to simulate the formation of …

Effects of Coarse Aggregate Morphological Characteristics on Mechanical Performance of Stone Matrix Asphalt
… the relationship between the uncompacted void content of coarse aggregates and morphological characteristics. To achieve the first research objective, a Fourier Transform Interferometry (FTI) system was adopted to capture three-dimensional high-resolution images of aggregates. Based on …

An analysis of impact factors on the Illinois flexibility index test
… asphalt concrete materials with high recycled content have been shown to have some performance issues, leading to deterioration before the end of the design life. This early deterioration may negate any environmental or economic benefit initially obtained from the use of recycled materials. The …
