TRANSPORTEFFEKTIVITET AV SCHAKTMASSOR OCH DESS MILJÖPÅVERKAN

Sammanfattning: Society is aiming to move towards higher sustainability. To achieve the climategoals for future sustainability we need to lower our carbon emissions in every area possible. The transportation of excavation masses with trucks is hard to avoid since it is not easily replaced. However, transportation can be conducted more efficiently to decrease the negative impacts. This study aims to analyze the transport efficiency between different types of excavation masses and estimate the economic loss and unnecessary carbon emissions an ineffective usage of diesel fuel is responsible for. The study also investigates to what degree the visualization of the degree of filling for drivers and contractors of trucks can improve transport effectiveness over the duration of a specific ongoing project. This is done by analyzing data, plotting simple graphs, and using a simple mathematical model in Excel with data provided by Pinpointer AB. The conclusion of the study was that there are significant differences in the transport efficiency of different excavation masses, especially concrete which showed very high average distances in its transportation. The estimated amount of ineffective diesel fuel usage is calculated to be 2452 liters. Visualization of the degree of filling did not show an increase in the degree of filling over the duration of a specific project, which indicates that the data have not been used in the intended way, to follow up and improve the degree of filling.
