Syfte: Problemet med hårdgjorda ytor, som exempelvis asfalt och tak, är att de inte absorberar dagvattnet tillräckligt. Vidare leder detta till att gräsytor och andra absorberande ytor runt omkring måste ta hand om det dagvatten som inte de hårdgjorda ytorna kan tillvarata. Översvämningar i urbana miljöer har blivit allt vanligare på grund av kraftiga regn och stor andel hårdgjorda ytor. Detta leder till att ledningsnätet för dagvatten blir överbelastat. Därmed behövs väl fungerande utjämningsmagasin nära källan för att efterlikna naturens naturliga avrinningsförlopp. Målet var att utreda vilken eller vilka utjämningsmagasin som främst bör tillämpas i starkt hårdgjorda små radhustomter, med avseende på effektivitet, kostnad och underhåll, då jordmånen har begränsade infiltrationsegenskaper. Metod: De metoder som har använts för att svara mot målet är dokumentanalys, kvalitativ intervju och fallstudie. Dokumentanalysen fungerade som underlag för fallstudien och intervjuerna fungerade som bidragande empiri för fallstudien. Resultat: Det utjämningsmagasin som är att föredra är rörmagasin när anläggningsytan är begränsad och jordmånen har begränsade infiltrationsegenskaper. Konsekvenser: I problembeskrivningen beskrivs problemet med att det blir allt fler översvämningar i urbana miljöer på grund av de hårdgjorda ytorna och de kraftiga regnen. Vidare beskrivs det att ledningssystemet därför riskerar att bli överbelastat. Detta problem bekräftades även i intervjuerna. Arbetet löste inte vilket utjämningsmagasin som är att föredra för alla typer av fall, utan för fall där tomtytan är begränsad och där jordmånen har begränsade infiltrationsegenskaper. Lösningen på problemet är därför att rörmagasin är det utjämningsmagasin som är att föredra vid lokalt omhändertagande av dagvatten vid dessa förhållanden. Vid tillämpning av detta resultat i verkligheten rekommenderas det att använda kostnaderna per meter och utjämningsvolym per meter som finns i arbetet för att komma fram till hur lång sträcka som rörmagasinet behöver anläggas på för att uppnå önskad utjämningsvolym. Poängsättningen som har gjorts för underhållet kan däremot återanvändas till andra fall. Begränsningar: Resultatet är tillämpbart i liknande typfall som för fallstudien, alltså vid radhus där ytan för utjämningsmagasinet är begränsat och där jordmånen har begränsade infiltrationsegenskaper. I arbetet har ett diagram tagits fram där anläggningskostnaden per meter framgår för respektive utjämningsmagasin och ett diagram med utjämnad volym dagvatten per meter. Dessa diagram kan därför tillämpas på andra fall med små ytor men med lite andra mått på tomten. Därav är resultatet även tillämpbart på andra fall. / Purpose: The problem with hard surfaces, as for example asphalt and roofing, is that they do not absorb enough rainwater. Furthermore, this leads to that grass surfaces and other absorbent surfaces around having to take care of all stormwater that the hardened surfaces cannot infiltrate. Flooding in urban environments has become increasingly common due to heavy rain and a high proportion of hard surfaces. This leads to an overload of the pipe line for rainwater. Therefore well-functioning balancing trays close to source needed to mimic natural drainage of nature. The goal was to investigate witch countervailing magazine mainly should be applied in heavily paved small terraced plots, where the soil has limited infiltration properties, in terms of efficiency, cost and maintenance. Method: The methods used to meet the objective is analysis of documents, qualitative interviews and a case study. The document analysis serves as a basis for the case study and interviews serve as empirical input for the case study. Findings: The countervailing magazine that is preferred is the pipe magazine when the plant surface is limited and the soil has limited infiltration properties. Implications: The problem statement treats the issue with an increasing number of floodings in urban environments due to the paved surfaces and the heavy rains. Furthermore, it is disclosed that the management system therefore risks becoming overloaded. This problem was also confirmed in the interviews. The work did not identify which countervailing magazine that is preferred for all kinds of cases, but only in the cases where land space is limited and where the soil has limited infiltration properties. The solution is therefore that pipe magazine is the magazine preferred for local disposal of stormwater in those circumstances. It is recommended when applying this result real life, to use the cost per meter and countervailing volume per meter available in efforts to work out how long stretch pipe magazine needs to be built on to achieve the desired equalization volume. Rating systems made for maintenance can however be used for other cases. Limitations: The result is applicable in similar scenarios as for the case study, which is at a row house site where the surface for the magazine is limited and where the soil has limited infiltration properties. A graph has been developed for the work where the construction cost per meter is described for each countervailing magazine and also has a graph with stormwater volume per meter been developed. These diagrams can therefore be applied to other cases with small areas but with other measures of the plot. Therefore the result also is applicable to other cases.

Foram feitos estudos do material de subleito em cerca de 17 seções distribuidas nas diversas rodovias. As estimativas de tráfego para o tempo de serviço e de projeto, foram avaliadas e comparadas com base nos métodos de Murillo Lopes e da Gran Bretanha. Os parâmetros de resistência dos solos de subleitos, obtidos nos ensaios CBR com e sem imersão, foram relaciona dos com a resistência determinada pelo CBR "in situ". realizou-seum estudo sobre a distribuição de umidade dos subleitos em relação aos valores de sucção obtidos no laboratório. Os resultados encontrados nesta pesquisa, indicaram que o dimensionamento de pavimentos baseado nos resultados dos ensaios de CBR com amostras saturadas, não são adequados para regiões de climas secos. O ensaio CBR para o teor de umidade de equilíbrio, provavelmente fornecerá uma indicação da capacidade de suporte do solo mais coerente com aquela que e de se esperar em serviço. Propõe-se que a umidade de equilíbrio possa ser tomada como aquela correspondente a umidade ótima para o Peso Específico Aparente Máximo. Os ensaios de laboratório para obter as relações de sucção-umidade, não forneceram dados precisos para avaliar a umidade de equilíbrio, devido aos níveis do lençol freático serem muito profundos e não influenciarem nos valores de umidadede equilíbrio. Esta umidade, possivelmente, é determinada por transferência da água na fase de vapor e transferência da mesma dos acostamentos para o centro da rodovia. / A field and Laboratory investigation in described concerning the engineering properties and subgrade conditions of paved roads located in Paraiba State in Different topographic and climatic areas and soil formations. Subgrade materials from seventeen sections of different roads were studied. Traffic volumes for service and project times were determined and evaluated using the Murillo Lopes and the English methods. Subgrade soil resistance parameters obtained in CBR tests with and without immersion were compared with CBR value determined "in situ". A study was also carried out rela ting the distribution of moisture contents in the subgrade to the suction values obtained in Laboratory. The results obtained in this research indicated that pavement design, based on CBR result with saturated specif mens, is not adequate for dry climate regions. A CBR test for equilibrium moisture content, could possibly be an indication of the bearing capacity of the soil which can be expected in service. It is suggested that the equilibrium be taken as that which corresponds to the optimum moisture content for maximum dry unit weight. The laboratory results used to obtains the suction moisture relationships, did not provide data precise enough to evaluate the equilibrium moisture, due to the fact that the wa ter table levels were very deep and did not influence the equilibrium moisture values which were probably determined by trans ference of the water in the vapor state as well as by the transference from the shoulders to the center of the road.

The diploma thesis deals with the design of a multifunctional house on the street Křídlovická in the city of Brno. The new building is five-storey with four above-ground and one underground floors. The main entrance is oriented to the southeastern side and adjacent to the northwest side, and a separate entrance to the underground garage in the southwest corner of the designed object. Behind the main entrance is a staircase connecting all floors, after a special entrance for the underground garage is the staircase down into the garage. From the southwest side there are entrances to restaurants and shops, these have staffing and supply entrances and social facilities from the north-east side of the building. A downhill ramp is also located behind the northeast side of the building, from the southwest side are solved areas - restaurant garden, sidewalks and parking areas. In other above-ground floors, open space office spaces with separate meeting rooms, office director, secretary offices, and social facilities on the northeastern side of the floor are designed. Within these floors is proposed continuous greening of the atrium. The supporting system is a monolithic reinforced concrete combined with masonry staircases and a northeast wall. In the basement, the support system is a skeleton in combination with the walls of a lost formwork. Roof flat single-skinned with various inclinations 1-5°
