Nanomaterials exhibit novel properties and profound attributes as an additive in asphalt binder modification. However, the application of nano-silica binders mixture modification is still limited, further research required. Along these lines, this work, with a content from 2% to 8% increment was utilized modifying bitumen type C320, which considered most conventional used Western Australia road...

according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...

This paper presents an investigation on mechanism of the inclined 1 cone penetration test (CPT) using the numerical discrete element method (DEM). 2 A series of penetration tests with the penetrometer inclined at different angles 3 (i.e., 0°,15°, 30°, 45° and 60°) were numerically performed under µ=0.0 and 4 µ=0.5, where µ is the frictional coefficient between the penetrometer and the soil. 5 T...

Natural substrates like sand, soil, leaf litter and snow vary widely in penetration resistance. To search for principles of appendage design in robots and animals that permit high performance on such flowable ground, we developed a ground control technique by which the penetration resistance of a dry granular substrate could be widely and rapidly varied. The approach was embodied in a device co...

Abstract. A horizontal, on-line penetrometer has been used on several fields in Sweden to measure penetration resistance. The yield on these fields have been mapped and compared to the penetration resistance. In some of the fields, deep loosening has been done on parts of the field in order to be able to study the effects on the yield. Some correlation of higher penetration resistance and lower...
