Pervious concrete (PC) is at risk of clogging due to the continuous blockage sand into it during its service time. This study aims evaluate and predict such behavior PC using hybrid machine learning techniques. Based on 84 groups dataset developed in earlier study, was determined by algorithm combing SVM (support vector machines) particle swarm optimization (PSO) methods. The PSO employed adjus...

Abstract From the late 1960’s airport engineers developed special paving material for arresting aircraft gears in event of overrun as a partial extension runway end safety area. Such pavement surface material, inverting general concept, should be crushed over first pass gear wheels resulting to sink and being promptly arrested abrupt loss velocity, preferability avoiding lives injuries well wit...

 Permasalahan terkait kerusakan jalan saat ini semakin berkembang. Kerusakan-kerusakan yang terjadi seringkali diakibatkan karena genangan air. Salah satu upaya bisa dilakukan yakni dengan menerapkan penggunaan beton porous (pervious concrete). Beton dapat mengurangi limpasan air dan menambah infiltrasi dalam tanah memiliki nilai porositas tinggi. Sebagai bahan subtitusi, slag baja...

Brick-concrete demolition residue after the primary recycling is generally discarded due to its low quality. Secondary of brick-concrete urgently required be solved at present in China large scale constructions and demolitions, remains a challenging task. In this work, from an urban-fringe Hangzhou, China, was secondarily recycled as fine aggregate fabricate sustainable pervious concrete system...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...
