Abstract

Cold mix recycling with foamed bitumen is a technology alternative which can be implemented in selecting treatment strategy for road rehabilitation project. This construction is an environment friendly and can reduce air emission on road project. Mix material can consist of Reclaimed Asphait Pavement (RAP), virgin aggregate with or without cement addition.The criteria of recycling with foamed bitumen mixture based on value of Indirect Tensile Strength (ITS), Tensile Strength Ratio (TSR) and Unconfined Compressive Strength (UCS). Whereas the mix stiffness is based on Resilient Modulus (MR). The value of ITS and MR is influenced by laboratory testing or field temperature. The result form some specimens which were tested in some temperature variotions shows that the increased of test temperature, the ITS and MR decreased. There is significantly fair correlation between two parameters MR and ITS in power regression type. This prediction can be used as a guide to determine coefficient layer in pavement thickness design. Key word : cold mix recyling, foamed bitumen, RAP, ITS, Resilient Modulus, coefficient layer

Abstract

Conformity between the quality of hot mix asphalt construction with quality result is very difficult to achieve the plan. There are several factors that can lead to differences, among others, is the effect of lack of precision sampling, testing and manufacturing process ofthe mixture and implementation of the field. Difference of diversity of the construction is still acceptable as long as it within tolerance as specified in the specification. Tolerance in the specification reflect that the quality of the product is still acceptable because it is technically still within the range required. This paper discusses the range limit of bitumen content which still meet the requirements based Superpave specifications for various types and gradations of hot asphalt mixture, either for Laston of Lataston. Activities undertaken are included literature review, testig of materials and some types of hot mix asphalt in the laboratory and data analysis that includes a descriptive analysis to properties of material and hot mix asphalt. Analysis shows that the range limit of bitumen for hot mix asphalt-based refers to the Superpave specification, especially for the type of mixture of bitumen mixture which limits the range to meet varied requirements and more narrower (< 0.3%). As for the mixture Lataston was still quite wide, namely >= 0.4%. Since the range limit of bitumen content for Laston narrow enough, so in the process of sampling, testing and manufacturing process of the mixture and implementation of field is required precision and high accuracy. In this case associated with implementing a well-trained and well and calibrated equipment Key word : the range of bitumen content, hot mix asphalt, Superpave, tolerance, Laston and Lataston

Abstract

Integral bridge is made without existence of movement between spans or between spans with abutment. The road surface is continuously made by the approach embankment. The integral bridge type avoids the problem of maintenance for joins and bearings, in particular if water and dust penetrates through the joints and also effect the bearings, can made safe for road users and simple applicative method. Bridge integral system consist of full integral and semi integral. Integral bridge with spans less than 20 metre to the condition in Indonesia most aptimum use reinforced concrete type with system of full integral, while if more than 20 metre more suggested to user type of prestress with semi integral system. This study explaining about development of integral bridge technology for the type of concrete structure. like calculation method, encumbering paramter and also of desain with simulation model bridge user program analyse structure. For example made integral bridge model for the type of reinforced concrete with single span. Result of study of full integral most is optimum made to spans until 20 m. Keywords : full integral, semi integral, reinforced concrete, maintenance, expansion joint

Abstract

The road concrete pavements for high volume traffic load in Indonesia are mostly faced to the unstable base layer and eroded drainage factor then fallout deterioration such as irregular cracks, pumping, spalling ad faulting. The effect of those factors may appear propagation cracks or depression that needs demolition of whole concrete or apart of panel for repairing. The process requires a fast way repair, without hampering the flow of traffic. The defect must be identified causes and conditions carefully by means of visual condition assessment and mapping, deflection test with Falling Weigt Deflectometer (FWD), and sampling with core drill prior to repair. Based on the trials of concrete pavement suffers by pumping and depression, handling of the injected liquid cement ixed with a certain additive material, may reduce differential deflection so the slab is stable. Another repairs is the panel was removed and replaced with cast-in-place concrete using concrete mix that was given an additive to accelerate the hardening reaches 80% design strength, and within 3x24 hours can be immediately opened to traffic. The broken slab may also directtly be repalced using precast concrete with an appropriate dimension, the process is relatively fast then the traffic may immediately be opened. Monitoring result in improvements at the end of the first year, in the joint after grouting based on deflection criteria showed no indication of voids with a deflection of less than 0.05 mm (2 mils), and load transfer efficiency of more than 60%. This perform is usefull on preservation system of concrete pavement in Indonesia. Key words : pavement repairs, concrete pavement, segment cast in place, cement injection, precast concrete slab.

Abstract

Road improvement program such as geometric intersection improvement or traffic light should consider road safety and accessibility. Those could be evaluated in a short phase without waiting any accident data from police department or accident occurence but using the tool of traffic conflict study. With the tool, the effectiveness of road improvement program could be valued and evaluated. Traffic conflict study is a traffic event which two or more vehicles involved, and those vehicles take evasive act to avoid crashes. In Indonesia, traffic conflict has been used sevral times i.e. for motorcyle facilicty at intersection, intersection improvement, and traffic management at intersection. This paper describes traffic conflict application at one T-intersection to evaluate conflict resulting from the presence of an illegal traffic office (PTR). The method is comparing some conflict with and without PTR. The result showed taht the presence of OTR do not significantly influence on the number of severe and simple conflicts. In terms of conflict category, the major conflict is generated by turning movement to the right (conclict 1), conflict avoiding vechicles turning right on the same road lane (conflict 4), conflict avoiding vehicles turning right from opposite direction (conflict 7). To overcome such problems and to improve capacity, it should be applied an arrow mark for conflict in the same direction to tun right (category 1), and stop sign form conflict avoiding vehicle which turn right in the same road lane (category 4) and conflict avoiding vehicle turn right from opposite direction (category 7). Key words : conflict study, conflict severity, vehicle manouver, T-intersection, traffic volume.

Abstract

The arch of an arch bridge structure is mainly a compression member with curved linier parabolic shape. A great part of the uniform and moving loads is carried by compression forces prevent and reduce concrete tensioning due to traffic passage on the bridge. Existing old arch bridges still resist the increasing vehicle loads due to reserve capacity of the comperession member. Arch bridges reduce 15% concrete volume compared to straight girder bridges, so they are economical in dimensionand reinforcement. Arch bridges are classified into two types according to the thrust force transmission. The rigid arch type is optimal for very good soil conditions as the thrust force is directly transmitted to very good foundation soil. The stiffened arch type is suitable for deep foundation condition as the thrust force is carried by the structural tie beam. The monolithic system between super and sub structures with the number of plastic hinges improve the earthquake resistance. The construction of arch bridge always involves the need for formwork that is removed after the arch is connected and the compression line has been formed. An improperly connected arch will fail at the time of formwork removal. The maximum reinforced concrete arch span 90 m is efficient compared to the maximum prestressed concrete girder span 45 m. Composite reinforced concrete arch bridges with steel truss/profile for scaffolding as well reinforcement reach (90-245)m span. Key words : arch bridge, rigid arch, stiffened arch, thrust, compression line

Abstract

Passenger car equivalent (pce) converts unit of traffic flow from vehicles per hour to passenger car unit (pcu). A traffic flow consists of several types of vehicles such as passenger car, bus,truck, and motor cycle are converted to a uniform unit of traffic flow, ie. pcu, by assuming that a vehicle other than passenger car is 'replaced' by a passenger car multipled by pce. Each type of vehicle has its owned pce value and different from other, depending on influences of it's presence in a trafic flow. Basic capacity is a maximum number of vehicle that may be reached under a specified standard geometric condition and by an undisturb traffic condition. Pce is used to convert unit of a basic capacity from vehicles/hour to pcu/hour. This paper aimed to discus methods of defining pce and basic capaity of inter urban roads, including data required for testing capacity of inter urban roads, including data required for testing applicabiliy of the method. The review showed that for inter urban road segment, pce may be derived from a relationship between speeds versus flow rate of each individual type of vehicles, whereas the basic capacity may be derived from a linear relationship between densities versus speeds. Application of the method to a set of traffic flow data showed that the method may be used for defining values of emp and basic capacity. The results of analyzing a segment of Nagreg-Tasikmalaya data showed that emp and basic capacity tend to change. Key words : Inter-urban roads, road capacity, speed-density relationship, pce, pcu
