5 till 7 miljoner ton asfalt har tillverkats och lagts ut under de senaste åren i Sverige och anläggningsbranschens årliga omsättning ligger på ca 4 mljarder kronor per år. Samtidigt har asfaltmarknadsbranschens upphandlingsmetoder varit ett diskutabelt ämne runt om i världen. Examensarbetet består av en geografisk prisjämförelse av asfalt och studera de ingående faktorer som påverkar priset. Intervjuer har gjorts med beläggningsentreprenörer från olika företag i Mellan- till Sydsverige. Resultatet påverkas av att reliabiliteten är låg eftersom relativt få aktörer har svarat på frågeformuläret, men visar på kraftiga prisskillnader mellan olika regioner. Totalkostnaden för beläggning, emulsion, bergmaterial, transport, maskin och hantverk skilde nästan 50 % mellan den med lägst och den med högst pris. Det har inte framkommit några indikationer på kartellbildning i denna undersökning.

This report deals with environmental improvement measures in asphalt production and examines the willingness to invest in environmentally friendly technologies. The main reasons of this paper are that the asphalt industry have a large impact on the environment and the transition to green technologies is slow, and to clarify the opportunities around environmentally friendly asphalt production. The main purpose of this report is to compile relevant knowledge in the improvement of the environmental measures of the asphalt production and thus contribute to a faster reduction of carbon dioxide emissions. The questions covered are: • How has the asphalt been used over time and until? • How does the asphalt industry effect the environment? • What are the technical solutions? • What are the costs of the different technical solutions? • What is the trend for more environmentally friendly asphalt production? The thesis was concluded through literature studies, consultations with people in the asphalt industry and trough several interviews. The results of the report show that there are many different measures to reduce the environmental impacts from asphalt production, and the main challenge for producers is to choose which method is most suitable for their company. The interviews report that the willingness to invest in environmentally improving techniques exists and that the trend to produce more environmentally friendly will increase. Increased requirements and a greater demand for environmentally friendly asphalt production from customers are desired.
