Sport surfaces in warm and dusty climate
(2017) MMK820 20171Innovation
- Abstract
- This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty.
One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the surface’s open structure and accumulates on it which gives the surface a dusty color and blocks the open structure of it. The maintenance machines which are assigned to maintain the polyurethane sport surfaces are not cleaning it so that it restores its original look. Mainly, the word maintenance refers here to cleaning not repairing.

One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the surface’s open structure and accumulates on it which gives the surface a dusty color and blocks the open structure of it. The maintenance machines which are assigned to maintain the polyurethane sport surfaces are not cleaning it so that it restores its original look. Mainly, the word maintenance refers here to cleaning not repairing.
To solve the maintenance problem, another cleaning machine was suggested which uses high pressure water that could satisfy the needs of the customer. The approach used to solve this problem is inspired by the Product Design and Development method developed by Ulrich and Eppinger: the customer needs were gathered and formulated to criteria which became strict guidelines for a comparison between the suggested machine (KBR) and the maintenance machine used at the time being (Nilfisk). To gather enough data a field test was conducted which could not be completed properly due to that the Nilfisk machine broke. Despite the fact that all data necessary to perform the comparison was not gathered completely but a comparison was performed and the KBR machine was the winning concept. Extracting the dust from KBR’s dirty water shows that the capacity of cleaning (COC) is 88,4%, this means that the KBR could clean 88,4% of the dust used at test which is an excellent result and satisfies the customer needs.
Regarding most of the non-maintenance problems in the polyurethane sport surfaces, a cause analysis showed that they are originated from the bad implementing of the concrete substrate and the thin thickness of the top layer of the surface. In order to solve these problems great care should be taken to inspect the concrete substrate to avoid future problems such as cracking, visual seams as well as the irregularity of the surface. Using the original designed thickness of the top layer is an important issue to avoid the top layer gets ripped off. (Less)
