Abstract

Today the implementation of road infrastructure development using concrete pavement is experiencing rapid development because it can serve heavy and heavy traffic loads. But there are some problems that often arise in the use of concrete for pavement, causing damage (cracks). Repair of concrete cracks using pressure grouting method is one solution that can be used to improve the strength of concrete. This study discusses the comparison of the effectiveness of using polyurethane and epoxy materials in an effort to improve the rigid pavement structure. The research method used was to carry out repairs to the concrete structure on the Independence Patriotic-Road Section of Pekalongan City using polyurethane and epoxy materials. In this study each of the 5 existing normal (non-damaged) concrete samples, concrete repaired with polyurethane material and repaired concrete using epoxy material using core drill method, which will then be tested for compressive strength in the laboratory, as well as hammer test testing. to find out the strength of the existing concrete damage. The results showed that the average compressive strength of normal existing concrete (not damaged) amounted to 59.20 N/mm2, the average compressive strength of concrete that experienced cracks was 27.04 N/mm2, the average compressive strength value of repair concrete using polyurethane material is 31.92 N/mm2 (increasing by 15.17%) and the average compressive strength of concrete repair using epoxy material is 45.22 N/mm2 (increased by 56.53%).

Abstract

In line with the economical development, there are a lot of old buildings renovation which produces material waste like roof tile.To use the existing roof tile waste, the research on the use of cncrete roof tile waste for concrete mixture was performed considering that concrete roof tele fraction is hard enough. By using part of concrete roof tile fraction in the agregate for concrete mixture, it is expected that it doesn’t affect the quality or pressure strength of produced concrete. This is more economical since the pebble price is more expensive than concrete roof tile price. The aim of the reseach is to find out the percentage of concrete roof tile fraction in the coarse aggregate for concrete mixture so that it doesn’t affect the concrete pressure strenght, seek for the correlation between concrete pressure strenght and the precentage of concrete roof tile fraction in coarse aggregate for concrete mixture, seek for the correlation between concrete pressure strenght and aggregate weathering. In the research, the testing material is in the form of cube 15 x 15 x 15 cm with slump value as the fixed variable mean while the non fixed variable is the precentage of concrete roof tile fraction in the mixture, that is 0, 10, 20, 30, 40, 50 % of is coarse aggregate. From the result of the research, it is obtained that in the 10 % percentage of concrete roof tile fraction, the generated concrete pressure strength doesn’t change or has no influence. The correlation between concrete pressure strength and the percentage of concrete roof tile fraction in the aggregate is y = -1.539 x + 242.6 and the correlation between concrete pressure strength and the aggregate weathering is y = -6.519 x2 + 242.2 x – 2013. With the percentage ot roof tile fraction in the aggregate asmuch as 50 % may affects the decreasing of concrete quality and the concrete pressure strength reaches 29.5%.

Abstract

The road is the basic infrastructure and major in propelling the national economy and local governments, considering important and its strategic function of road to push the distribution of goods and services as well as the population mobility. It is necessary for planning the structure of his stardom is a strong, durable and have a high durability against plastis deformation. As a indication factor if the cause of the overload or often called Physical Damage factor (P.D.F.), load repetition and drainage function less well. The third factor is the main cause of damage to road roughness is demanding the use of the material for the road roughness with better quality, in the form of aggregate materials as fillers are primarily asphalt or as a binder. This research was conducted to measure up to abaout performance of the asphalt Pertamina Pen 60/70 and BNA Blend 75/25 on hot mix asphalt AC-WC to the characteristics of the Marshall and the results are expected to provide information in the field of street work. The results showed that the value of the characteristics of Marshall on the optimum asphalt content (OBC), the mixture of the Laston AC-WC using BNA Blend 75/25 (mixture “B”) has better characteristics than the Laston AC-WC using asphalt Pertamina Pen 60/70 (mixture “A”). Shown with Marshall Stability on mixture “B”amounted to 1088.621 kg higher than the mixture “A” amounted to 891.902 kg. Marshall Quotient (MQ) value mixture “B” amounted to 327.86 kg/mm higher than the mixture “A” amounted to 284.98 kg/mm, can be interpreted as indicating a high ability of MQ receive traffic load repetition, friction wheels of vehicels on the road surface and the ability to withstand wear and tear due to the influence of temperature changes. From these results reinforce answered the initial hypothesis that the BNA Blend 75/25 is more durable than asphalt Pertamina Pen 60/70.

Abstract

Environmental problems such as pollution, destruction and disasters over the years is still ongoing and increasingly widespread. The condition not only causes environmental degradation but also a very serious impact on health and the human soul. Damage to the environment due to the soil / land also occurred in Waterford District C in the form of mineral mining (gravel). Mining is long overdue and is expanding. The existence of the mine excavation C has caused another problem in the form of accumulated waste material in gravel scattered around the place and the mining area. Starting from the above, it is necessary to think about how to take advantage of the rest of the mine rock gravel on aspalisasi activities. Step that needs to be done is to study the quality and characteristics of the asphalt mix by stacking materials using the gravel with reference to the specifications and requirements specified. This paper presents the results of research into the use of coarse aggregate gravel quarry C residue and fly ash filler in asphalt Hot Rolled Asphalt (HRA) in terms of the relative strength coefficients (a1) material in order to know the needs of pavement thickness HRA in the field.Coarse aggregate materials used in the study came from the residual quarry village C Munggangsari / Purbosari excl. Ngadirejo kab. Waterford, fly ash material derived from PT Jati Kencana Concrete (Ungaran) and AC 60/70 bitumen production Pertamina Cilacap. Equipment used for the study is the means test in the asphalt mixture Materials Laboratory of Civil Engineering Department Semarang State Polytechnic. Number of test specimens to be used in this study is 30 pieces and the test is done with reference to the SNI 06-2489-1990, including the value of stability, flow and MQ, density analysis and voids (VMA, VFWA, VITM). The study results showed that the residual gravel excavation C can be used as a mixture in which the HRA asphalt mix asphalt with gravel aggregate quarrying C has a value of stability between the above 744, the value of a1 between 0.28 to 0.38 which means it can support the traffic with heavy density. Based on the results of plotting the data parameters to the requirements of Highways marshall, obtained the optimum bitumen content of 7%. While based on a mixture of the three variations of rock and ash content of different fly ash show that the levels of HRA mixture with 100% filler stone dust showed the highest value a1. This shows that the addition of aditive fly ash as filler in the mix HRA HRA instead lowered pavement performance.

Abstract

Semarang is a beach city that is potential for sea water intrusion process happened. Correlation to the sustainable development programs in our country especially environment-conservations aspect, it is important to be known, and need to be monitored and controlled.Contamination in land water is a serious probleme, becouse it makes water quality decrease. Sea water intrusion is one of contaminant resources to the land water that cause hight concentration of salt. It is identified by concentration level of chloride (Cl) that come from sea water by mass transportation process of chloride (Cl) to the land water, and so the volume of land water that is fullfill in quality standard limited. Focus of the research is identifying distributions of factor that cause sea water intrusions happened to the land water in inner aquifer in Semarang area. Method of research, by determining of monitoring wells of ESDM service as sample points, continued to measuring concentrations of chloride (Cl) continuously and identifies factor causes the intrusions. To describe the distributions is used the ArcGIS application programs, and to know correlations of chloride’s concentrations to time changes is used correlations statistics test. The result of research showed that sea water intrusions which are identified the chloride (Cl) concentrations and exceeded the quality standard (PERMENKES No. 492/MENKES/PER/IV/2010), in 1992 only one of them, that is monitory wells on STM Perkapalan, north of Semarang. And in 2013, the intrusions happened in 6 (six) areas, those are monitory wells on STM Perkapalan, PRPP, Pelabuhan Tanjung Mas, Simpang Lima, PT Panca Jaya and LIK Kaligawe located in areas of : Kecamatan west of Semarang, nort of Semarang, middle of Semarang and Gayamsari. Factors which cause sea water intrusions are : the increase of populations effects the water reserve decreases to be about 125,7 .106 m3, Land water head changes that caused by descending (sinking) of land , changings of land water surface level from sea level make the distributions of intrusion go to short -east direction, and there is correlation between Chloride’s concentrations level changes to the times changes by the constant of correlations about R = 0,704 to R = 0,997.
