Heated bitumen yields the superior position to bitumen emulsion in road construction projects. Emulsions have better adhesive properties, are more easily spread over the road surface cover, and can be laid on a damp base. Due to high penetration rates, emulsions easily fill the cracks and irregularities in the roadway. Modern, technologically advanced equipment isRead More
Catalysts are special substances that speed up chemical reactions while remaining unchanged themselves. Unlike other reagents, catalysts remain unchanged when the process is finished. The reaction proceeds more slowly or does not proceed at all without catalysts. The essence of catalytic reactions can be summarized as follows: First, the catalyst reacts with original substance. AnRead More
Hummus is a dish known since the times of Pharaohs. The following is the list of ingredients, necessary for its preparation: chickpea; lemon juice; olive oil; garlic; paprika; sesame paste. In modern times, in some countries the word “hummus” means not only cold snack but also chickpea. You may wonder, why are chickpeas used toRead More
Bitumen emulsions are used for road surface treatment, soil reinforcement, and ground stabilization as well as for the construction of roads and highways. Bitumen emulsion usually consists of bitumen (50-70%) and water (30-50%). A special component known as an emulsifier (acidol, naphtha soap, sulphate soap) is added to bitumen emulsion to make it stable. TheRead More
Nowadays, we can’t even imagine our lives without toothpaste. In general, they consist of abrasives, binding components, surfactants, aromatics, and antiseptics. Often, such chemical elements known as ‘propyl p-hydroxybenzoate‘ are used as an antiseptic. Additionally, pastes may contain various medical and preventive additives such as chlorophyllin sodium, provitamins and vitamins, herbal infusions, salts, microcomponents, andRead More
It is has always been difficult to provide a competely effective road surface pavement because of the wide range of factors such as: (1) short road construction seasons; (2) unpredictable and unfavourable weather conditions; (3) shortage of financial resources; The situation had remained unchanged for a long period of time, but recent developments with bitumenRead More
Storage and preparation of bitumen on your own company property has a number of advantages for the company. The availability of bitumen boilers allows companies to create and replenish their own stocks of the material without fear of market fluctuations and irregular supply. There are various special containers for storage and heating of bitumen. GlobeCoreRead More
Early February, members of GlobeCore had a business trip to Baku (Azerbaijan). The purpose of the trip was commissioning and launching of the previously supplied UVB-1 plant (capacity of 2 m3/h), designed to produce bitumen emulsions. The project was completed on time, in full compliance with international quality standards – which allowed the workers ofRead More
Bitumen is an important adhesive component of mixtures used in road construction projects. This substance is used only in a liquid form therefore, it must be subjected to heating. As much as 70% of bitumen emulsion is made of the solid substance called bitumen. The particles of the bitumen are suspended in water. Additionally, bitumenRead More
Bitumen emulsion for road construction is a colloidal dispersion consisting of two components, bitumen and water that do not blend. The emulsion for road construction is made by the dispersion of bitumen in water solvent of emulsifier. The performance characteristics of the latter influences the process of bitumen emulsion production. One way (direct) is thatRead More
