There are many parameters that could affect the properties of asphalt mixtures, such as fiber additive, gradation type, nominal maximum aggregate size (NMAS), and asphalt. To evaluate influence these factors on crack resistance mixture, 10 different types mixtures were prepared. The indirect tensile cracking test (IDEAL-CT) semi-circle bending (SCB) adopted to anti-cracking ability samples. two...
Lignin is the second-largest plant polymer on Earth after cellulose. About 98% of lignin produced in papermaking and pulping industry used for combustion heating or power generation. Less than 2% more valuable fields, mainly formulation dispersants, adhesives, surfactants. Asphalt one most important materials pavement engineering. It a dark brown complex mixture composed hydrocarbons with diffe...
Asphalt (cheap and available in huge amount in Jordan) was converted into activated carbon powder by chemical treatment with sulphuric and nitric acids at 450 8C. The final product was characterized and found effective as adsorbent material. Its cation exchange capacity reaches 191.2 meq/100-g carbons when treated with 30 wt% acid/asphalt ratio without airflow rate injection and 208 meq/100-g c...
A Breakthrough Concept in the Preparation of Highly-Sustainable Photocatalytic Warm Asphalt Mixtures
The objective of this study is to test the hypothesis that titanium dioxide (TiO2) can function as a photocatalytic compound when used in the preparation of warm-mix asphalt (WMA). The proposed asphalt mixture would combine the benefits of WMA such as reduced energy consumption and emission during production with the photocatalytic properties of TiO2 to trap and degrade organic and inorganic pa...
One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long-term performance in service. Thus, epoxy resin was introduced industry to tackle deformation mixtures due thermosetting nature. In this review, as a dominant component epoxy-asphalt composite system first considered, followed by ...
The behaviour of an asphalt concrete structure subjected to severe loading, such as blast and impact loadings, is becoming critical for safety and anti-terrorist reasons. With the development of high-speed computational capabilities, it is possible to carry out the numerical simulation of an asphalt concrete structure subjected to blast or impact loading. In the simulation, the constitutive mod...
In the Campeche Knolls, in the southern Gulf of Mexico, lava-like flows of solidified asphalt cover more than 1 square kilometer of the rim of a dissected salt dome at a depth of 3000 meters below sea level. Chemosynthetic tubeworms and bivalves colonize the sea floor near the asphalt, which chilled and contracted after discharge. The site also includes oil seeps, gas hydrate deposits, locally ...
The sustainability movement has established a firm foothold in the Civil Engineering profession. The use of recycled asphalt shingles (RAS) is the latest development in the world of asphalt pavement sustainability. The relative abundance of tear-off shingles and their high asphalt content is driving RAS usage in highway and airfield pavements. However, the ultimate objective of any pavement sys...
The use of micromobility vehicles is considerably growing in cities worldwide. As a result, crashes involving these are also increasing, with single-bicycle accounting for significant percentage. In most infrastructure-related crashes, the road surface was slippery. this context, study pavement skid resistance crucial to improve safety. research, British pendulum tester used test 5 different ty...
