Abstract
The paper presents selected factors that affect the energy consumption during the technological process of hot mix asphalt production and the level of fuel consumption depending on the moisture content of mineral aggregates located on the plant site. Basing on earlier investigations, measurements and analyses, as well as on working experience in organization and control system to exclude unnecessary energy loss during hot mix asphalt production, the authors reviewed the available worldwide literature on the topic. Attention was directed to the mathematical-physical dependence and the results of engineer measurements regarding the authors’ own research. Between 2007–2009 consumption of fuel and aggregate moisture content on the plant sites and hot mix asphalt production parameters were measured to verify the analyses and conclusions found in literature. The authors focused on the problem of the production capacity relating to the consumption of fuel. This paper is an attempt to define the possibility of energy-consumption reduction during hot mix asphalt production through suitable work organization or technical solutions. The paper presents the discussion over the authors’ own results of investigations as well as results of analyses of other authors in the concerned field.
Highlights
The paper continues and widens the subject of the paper published in the Proceedings of 10th International Conference in Vilnius (Lithuania) in May 2010 (Grabowski, Janowski 2010).The object of the paper is to recognize the influence of selected factors on energy consumption during the hot mix asphalt (HMA) production and to define the level of fuel consumption depending on aggregate moisture in relation to the organization of HMA production process
The daily start-up of the asphalt mixing plant (AMP) uses an immense amount of energy and has fundamental influence on fuel consumption during the daily production up to 1000 t of HMA, this range of production is characterized by strong differences in the fuel consumption
In 2008, the planned coordination of the deliveries for each aggregate fraction for the HMA production, especially in the period of increased precipitation, allowed to reduce the level of moisture content of the aggregate located on the plant site, mainly of the 0/2 mm (0/5 mm) fraction, from 1% to 3% in comparison to the period of 2007, which was characterized by unfavourable weather conditions
Summary
The paper continues and widens the subject of the paper published in the Proceedings of 10th International Conference in Vilnius (Lithuania) in May 2010 (Grabowski, Janowski 2010). The object of the paper is to recognize the influence of selected factors on energy consumption during the hot mix asphalt (HMA) production and to define the level of fuel consumption depending on aggregate moisture in relation to the organization of HMA production process. The paper is based on the results of the authors’ own research conducted for several years. The research conducted since 2007 proved that the moisture of fine aggregate and the efficiency of the asphalt mixing plant (AMP) producing HMA have the highest impact on energy consumption during HMA process. Basing on results of own measurements and research, the current status of knowledge was reviewed, with special emphasis on: theoretical, mathematical-physical aspects of fuel consumption and energy parameters; changes of aggregate moisture stored in the AMP; influence of air temperature and precipitation. The paper below concentrates on the problem of energy reduction
