To solve the problem of rutting and fatigue damage to asphalt pavement, rutting and fatigue performances of Qingchuan rock asphalt modified asphalt were studied, based on the dynamic shear rheometer test, the dynamic creep test, the rutting test, the indirect tensile fatigue test, the small-sized acceleration loading test, the compressive resilient modulus test, the BISAR3.0 Program and the rut...

Microbially-induced concrete corrosion in headspaces threatens wastewater infrastructure worldwide. Models for predicting corrosion rates in sewer pipe networks rely largely on information from culture-based investigations. In this study, the succession of microbes associated with corroding concrete was characterized over a one-year monitoring campaign using rRNA sequence-based phylogenetic met...

This paper aims to determine the Marshall properties of Asphalt Concrete-Wearing Course (AC-WC) and Hot Rolled Sheet-Wearing (HRS-WC) with utilization concrete waste also percentage added into AC-WC HRS-WC as substitute for coarse aggregates. During manufacture asphalt mixtures, aggregates, fine aggregates are required in large quantities. To reduce fresh mixtures road pavement, has become an a...

The conventional French fatigue test has yielded significantly different results for two asphalt materials with the same grade of pure asphalt. A research program was begun to study the influence of the asphalt nature on the fatigue behavior of asphalt materials. The program included full-scale experimentation on the circular test track of the Laboratoire Central des Ponts et Chaussees, laborat...

In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...

The chert gravels are a by-product of sand mining in the south Israel; reserves amount to tens millions tons and continue grow. attempts their comminution for production aggregates by conventional mechanical methods have not yet been successful due high abrasiveness, as well flaky form fracturing. This study was motivated need find an alternative method rock that would ensure aggregate line wit...
