Abstract Self compacting concrete (SCC) is a new construction material in the world. The aim of this research is to construct self compacting concrete with high compressive strength using combination of nano silica and micro silica. For this purpose, nano silica, micro silica, Portland cement type 2, superplasticizer (SP), and gravel and sand have been used. Three different groups of samples wi...

Mixing microcapsules encapsulating asphalt recycling agents into can effectively enhance its self-healing performance and alleviate the brittle cracking of pavements due to aging. In practical engineering applications, should have good thermal stability, mechanical properties, uniform dispersion in or concrete, for effective micro-cracks which occur as age. The microcapsule-containing is affect...

Basic oxygen furnace slag (BOF) is widely used in road construction, but there is a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA), containing stone mastic asphalt (SMA), porous asphalt (PA), and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag co...

Marshall Test design methods are used to design TLA modified asphalt mixture and base asphalt mixture respectively, and their pavement performance is tested. The results showed that there is a transforming coefficient of 1.15 between OAC of 40% TLA modified asphalt mixture and that of base asphalt mixture, and ultimate gradation of the TLA modified asphalt mixture is finer than previous gradati...

With millions of years of natural evolution, organisms have achieved sophisticated structures, patterns or textures with complex, spontaneous multifunctionality. Among all the fascinating characteristics observed in biosystems, self-cleaning ability is regarded as one of the most interesting topics in biomimicry because of its potential applications in various fields such as aerospace, energy c...

Modern economies are based on an efficient communications and transport infrastructure. In this context, road networks make essential contribution to the movement of large quantities raw materials, finished products as well human for productive or recreational purposes. order maintain optimal functioning infrastructure, it is necessary ensure high quality lanes. Road construction maintenance wo...
