Abstract

The road surface is often suffered from crack caused by high shrinkage property of clay as base soil. One of several methods to overcome this is by stabilizing it by adding Portland Pozzolan Cement (PPC) and dolomite in the clay. The method used in this research is experiment based on trial and error method. Mixture percentage used is 0%, 5%, 10%, 15% dan 20 % from total mixture weight, with hardening time 0 day, 7 days, 14 days, 21 days and 28 days. The results show that the more PPC mixture and dolomite percentage, the stronger the soil support strength (CBR value). The best result from this research is the mixture of clay, PPC and dolomite at 20% with hardening time of 28 days and CBR = 52,2757% (increases 1088,4211%).

Abstract

Concrete paving block for flooring is widely used as a material for the road pavement on campus, offices, sidewalks, roads, parking areas and so forth. This may imply that the use of paving blocks are so complex, so the need increases due to the practicality of installation and maintenance. Various attempts were made in an effort to improve the quality as a result of market competition of the paving block. As an alternative to improve the quality is the addition of sawdust in the manufacture of paving blocks. The purpose of this study was to determine the wear and tear, porosity and compressive strength of paving blocks with the addition of sawdust. The method used is an experimental method. Therefore, the study was obtained through the compressive strength, porosity and wear resistance by comparing the paving block that use the sawdust and without sawdust. The results showed the effect of adding sawdust to the compressive strength of paving blocks. For 5% sawdust addition , the results of the compressive strength of paving blocks are relatively the same as the compressive strength of paving blocks 0 % sawdust. But for the addition of 10 % and 15% sawdust, the decrease the compressive strength of paving blocks increasing significantly. The effect of the addition of sawdust on porosity and wear resistance is the higher sawdust paving block composition is, the higher porosity and the lower the wear resistance of paving blocks will be.

Abstract

This study attempted to use coal ash as a substitute material that meets the criteria for subbase mixtures. Initial mixture consisting of soil, sand and gravel. The mixture was separated into three variations in the ratio of each of the Variation I (10:50:40), Variation II (10:45:45) and the Variation III (10:60:30). Comparison of variation with the lowest CBR value is used as a benchmark for subbase mixed with coal ash that is Variation I. Subbase mixture was then divided into two compositions of coal ash as a substitute material for sand and as a substitute material for gravel. Composition I as a substitute consisting of sand, gravel and coal ash (fly ash, bottom ash) are distinguished into three variations in the ratio of each of the Variations IA (10:50: (10:30)), IB (10: 50: (15:25)), IC (10:50: (20:20)). Composition II as a substitute for gravel composed of soil, coal ash brick, brick fine coal ash, which is also divided into three variations of the IIA, IIB, IIC with the same ratio of each composition 10:50:40, the difference is the content of coal ash in coal ash brick respectively 10% fly ash, 20% fly ash and 25% bottom ash. Test on subbase layer consisting of a sieve analysis test, atterberg limit, compaction, CBR, and dissolved heavy metals test. The results showed non-soaked CBR value for all variations subbase mixed with coal ash which has been meeting the specifications required for subbase, while the condition of soaked CBR II only variations that meet specifications. Variation IIA is a good subbase mixture to use.

Abstract

Settlement of the building can happen and will be happened, it is very detrimental to the stability of the building above the subgrade. The decrease can be considered stable when settlement has been predicted in advance by testing in the laboratory so that the building can be anticipated when settlement takes place. Consolidation is a process of downsizing volume slowly on perfectly saturated soil with low permeability due to partial drainage of pore water. Void ratio at the end of each period increase of pressure (load) can be calculated from the reading of the gauge dial and so is the case with moisture (water content) or dry weight (dry weight) of soil samples at the end of the test. All the land that is stressed will experience strain in the soil skeleton. Integration strain (deformation per unit length) along the depth of which is influenced by pressured is called voltage reduction. Tests conducted on water content, Atterberg tests, density test, grain size distribution and consolidation. Before the initial load is given shows that the initial compression is relatively large, but after a given initial load of 5 kPa, 10 kPa, 20 kPa, 40 kPa, 80 kPa produces variations of pore number with time of loading each one day, showed that the decline in the smaller clay consolidation, meaning the presence of a load that produces variations void ratio can reduce the compression clay. The ratio of the addition of a load of 40 kPa, 80 kPa on the graph void ratio and pressure of 5 kPa looks irregular, 10 kPa, 20 kPa. This is because at 10 kPa and 20 kPa has reached the maximum so that the additional load reduction that results in void ratio variations will not affect the decrease, thus the ratio of the addition of a load that produces a good variation of void ratio is at 10 kPa and 20 kPa

Abstract

The level of soil density measured from the value of the dry volume weight. Testing was conducted on the physical properties of soil and compaction test on one day curing. In the standard compaction test variation I (6%, 8%, 10%, 12%, 14%), it is obtained optimum moisture content of 24% and a maximum dry volume weight value of 1.335 t / m3. Testing compaction variations II (7%, 9%, 11%, 13%, 15%), it is obtained optimum moisture content of 26.5% and a maximum dry volume weight value of 1,270 t /m3. At compaction testing modifications variation I (6%, 8%, 10%, 12%, 14%), it is obtained optimum moisture content of 14.4% and a maximum dry volume weight value of 1,870 t /m3. Testing compaction variations II (7%, 9%, 11%, 13%, 15%), it is obtained optimum moisture content of 13,7% and a maximum dry volume weight value by 1,94 t /m3. In the second test, the value of optimum moisture content greater than the first test, while the maximum weight of the dry volume is smaller than the first test. This shows that the addition of the percentage variation in the use of water in the compaction test with one day curing showed that the optimum water content decreases while the maximum dry weight of volume showed increase.

Abstract

Imbalances between the number of parking vehicles and off-street parking facilities resulted in parking generation to automatically take the off-street area. Based on analysis on road capacity in the Blawuran traditional market segment on Jl. Ahmad Yani, it is known that the service level still meet as Transportation Ministry No. KM14 of 2006, AASTHO 1973 and Morlok 1990. Value of capacity service availability on Jl. Ahmad Yani on Tuesday morning is free flow and Tuesday afternoon is steady stream. However, on Saturday night, the road section is near to unstable flow. On Tuesday morning, traffic density is low with medium to high velocity but could be controlled by driver according to speed maximum/minimum limits and physical road conditions. On Tuesday noon, traffic density is medium with high speed but still could be controlled by driver according to speed maximum/minimum limit and physical road contion as well. However, on Saturday night, the traffic density is so high with low speed as consequences even still controlled by driver. Total hourly parking vehicles is 15 vehicles/hour. This value is adjusted to supplied vehicles in and out of market which is 139 vehicles/hour. Therefore, parking availability is still adequate to accomodate vehicles in Blawuran traditional market.
