<p>As a result of Antonio Bonet’s first experiences with prefabrication, and his interest in geometry and the modulation of space, during his Argentinian stage in the 1950s, he developed two trials of totally industrialised serial dwellings. The BGB and BSC Systems, were two constructive models of comprehensive prefabrication that Bonet designed as possible technical solutions to the housing problems, and with which he attempted to improve the middle-of-the-road construction, between the traditional and the standardised. Without losing their references, contextualised within their production, and within the international debate around housing industrialisation, both systems were designed from the habitable space and from its tectonics, surpassing the technical or the constructive, to give rise to the quality of the architectural object. Contemplated as generalizable prototypes, Bonet designed a single-family house in the case of the BGB System, and a block of houses for a neighbourhood unit in the BSC System. In spite of the difference of scale, both prototypes considered the complete prefabrication of the house by means of perfectly modulated elements that would allow variations, and which would resolve the small interior scale of the furniture, the structure or the envelope.</p>

Water functions are very diverse for humans for daily needs such as drinking water, bathing, agriculture, development, aesthetics, and lower temperatures. Palembang is a lowland area dominated by wetlands, tidal swamps, and rivers. The types of houses on stilts on the banks of the Musi river are limas, Gudang, and Chinese stilt houses which are always associated with the water environment. The construction of roads replacing the role of rivers has realized people that the water environment has an important meaning for the house on stilts. The research objective was to explore the meaning of the water environment from various aspects for residents, stilt houses, and their environment. This research method is a case study with data collection through interviews, observation, measurements, and taking photos. Data and findings were analyzed and juxtaposed with images in the field. The road construction has eliminated part of the function of the river and influenced the change in orientation of the house on stilts. In conclusion, respect for the water environment including rivers has decreased, causing the quality of the river to decline, and the house on stilts cannot take advantage of the existence of the water environment optimally

The increase in traffic volume will cause a decrease in service due to decreased road capacity due to an increase in side constraints and due to the increase in traffic volume itself, which will ultimately cause the level of road saturation to increase. The situation occurred in the Umasukaer road section of the Malacca Regency. Therefore it is necessary to address improvements in the quality of the road in order to meet the feasibility of transportation facilities by taking into account the existing technical requirements. The results of planning found that through the 2015 LHR survey data with a prediction of an increase in traffic density of 6% per year, the LHR was obtained with a planned age of 7 years = 2540.7 vehicles/day/department and a 20-year plan life LHR = 5419.1 ked/day / major. The results of a gradual construction planning pavement study can be concluded that the planning model that has been designed is effective in strengthening road construction in accordance with existing technical requirements and efficient in terms of financing. The final results of gradual construction pavement thickness results are: Ashburton thickness (MS 744) = 8 cm, Ashburton (MS 744) = 13 cm, broken stone (CBR 100) = 20 cm, Sirtu (CBR 50) = 10 cm and CBR subgrade 5%. Pertambahan volume lalu lintas akan menyebabkan penurunan layanan diakibatkan menurunnya kapasitas jalan karena adanya peningkatan hambatan samping maupun karena beratambahnya volume lalu lintas itu sendiri yang pada akhirnya akan meyebabkan tingkat kejenuhan jalan meningkat. Keadaan tersebut terjadi ruas jalan Umasukaer Kabupaten Malaka, oleh karena itu perlu adanya penanganan perbaikan kualitas jalan agar memenuhi segi kelayakan sarana transportasi dengan memperhatikan syarat-syarat teknik yang ada. Hasil perencanaan didapatkan bahwa melalui data survey LHR tahun 2015 dengan prediksi peningkatan kepadatan lalu lintas sebesar 6% pertahun maka didapatkan LHR dengan umur rencana 7 tahun = 2540,7 kend/hr/jurusan dan LHR umur rencana 20 tahun = 5419,1 ked/hr/jurusan. Hasil studi perencanaan perkerasan konstruksi bertahap dapat diambil kesimpulan bahwa model perencaaan yang telah dirancang efektif dalam memperkerasa konstruksi jalan sesuai dengan syarat teknis yang ada serta efisien dalam hal pembiayaan. Hasil akhir tebal perkerasan konstruksi bertahap diperoleh hasil: Ketebalan Asbuton (MS 744) = 8 cm, Asbuton (MS 744) = 13 cm, batu pecah (CBR 100) = 20 cm, Sirtu (CBR 50) = 10 cm dan CBR tanah dasar 5%.

The paper studies the establishment and development history for road stone quality requirements and covers its manufacture in the pre-revolutionary Russia. It is shown that industrial-scale production of road stone was first initiated in Russia as late as at the end of the 19 century. Due to the development of road construction technologies, it became requisite to assess the quality of rocks used to produce crushed stone. The first speculative conclusions on the effect of moisture, mechanical and temperature loads on the quality of crushed stone were made in the middle of the 19 century; however, at the time, there was no uniformity in how to establish the material quality. Crushed stone quality indicators (strength, abrasion, grain shape, and some others) were formulated at the beginning of the 20 century, when mechanized crushed stone manufacturing methods were being first introduced in Russia. In the same period, methods were developed for establishing certain crushed stone quality indicators in laboratory conditions. The underlying principles for these methods, in fact, correspond to the current methods of testing physical and mechanical properties of rocks. The difference lies in the equipment design, experimental conditions, and quantitative assessments of the indicators studied. In general, the late 19 – early 20 centuries may be referred to as the period when the scientific approach was first applied to crushed stone quality studies in Russia and the foundations for its standardization were laid.

In Indonesia, the road construction has experienced a fairly good development. From a wide range of road constructions, flexible pavement is the most chosen one because its characteristics: easy, fast, and efficient. However, flexible pavement has many weaknesses, for example the premature damage on the road surface after some time passed by the traffic so that the road cannot reach the planned age. For that, it is done a research to add a hot asphalt mixture material that aims to improve the quality of the mixture results. The selected ingredient is natural water hyacinth. The method used is trial and error with reference of SNI 03-1737-1989. Variations used are 2%, 4%, 6%, 8% and 10% of the asphalt weight, asphalt level used is 5.72 %. Of the 5 variations of mixture used on Type XI Asphalt Concrete Layer, it is obtained the result that the water hyacinth fiber level which has the best score and meet the specifications of SNI 03-1737-1989 is on the percentage of 6% which obtained from calculation data using graphs and regression model where Marshall Stability is equal to 644,46 Kg, flow 3,39 mm, VMA (voids in the mineral aggregate) is equal to 13,83 %, VFWA (voids filled with asphalt) is equal to 65,35%, VIM (voids in the mix) is equal to 2,52 %, density of 2.31 gr/cc, and Marshall Quotient of 164.03 Kg / mm.

Air in Polish cities belongs to the most polluted in Europe due to numerous causes e.g. high volume of road traffic, inefficient road infrastructure, the utilisation of environment unfriendly vehicle propulsion. However, the culmination of poor air problem noticeably occurs in winter as a result of the need for supplying buildings with a great amount of heat energy to defy influence of severe climate conditions. One of the most important causes for such situation deals with the application of solid fuel-based heat sources for heating buildings. The widespread burning of cheap coal in outdated home stoves results in producing smoke rife that includes carcinogens like dioxins and benzo(a)pyrene, as well as the small sooty particles that are strongly linked to heart disease, respiratory diseases and other sickness. Economical and social reasons make the application of such energy sources popular among single family house owners. Popularity of single family houses in Polish cities thus makes air pollution problem even more serious. Therefore, the effectiveness of selected solutions which would hopefully help to limit low pollution emission are discussed in the paper. They correspond well to current Polish government air improvement initiatives towards the improvement of air quality in Polish cities.

The Difference

Focused on the lane occupancy phenomenon, this paper analyzes the roads during two different accidents to the evacuation period. Firstly, according to the statistical data, this paper calculated the correction coefficients under the road traffic condition, and then obtained the actual traffic capacity result at each moment of the road when combining the function model of the actual traffic capacity corrected by the running speed and the road traffic condition. Next the actual traffic capacity results are fitted to the Smooth spline interpolation, and then the actual traffic capacity is further verified by the traffic congestion situation. The actual traffic capacity of the road during the accident to evacuation is summarized as follows: the actual traffic capacity shows a nonlinear trend, that is, ascending-attenuating-recovering and gradually stabilizing. Finally, using Mann-Whitney U test to carry out the difference test on the actual traffic capacity, it is found that there is significant difference between the two groups of data, and the actual traffic capacity of the second case is stronger than that of the first one, and the reasons for the difference are analyzed as follows: the ratio of the steering traffic volume at the downstream intersection is different; this road section includes the community intersection and there are vehicles entering and leaving; meanwhile the speed of each lane is different and there are buildings near the lane. The above conclusions will provide theoretical basis for the traffic management department to correctly guide the vehicle driving, approve the road construction, design the road channelization plan, set the roadside parking space and the non-port-type bus stations.
