The evaluation of pavement strength has been conducted and developed for long. There are two different types of evaluation namely destructive and non destructive methods. The tools for non destructive techniques have rapidly developed such as Falling Weight Deflectometer (FWD), however, this equipment is very expensive so that big budget is required for it. Moreover, the number of road links served is long. Another simple equipment is Benkelman Beam (BB) which well known in Indonesia, cheap and more practical in use . This paper presents the relationship between the test results of the strength of the structural number of existing pavement structures in Central Java using FWD and BB obtaining from surface deflections and tangent of deflection bowl. The study reveals that a variety of relationships occurred so that careful consideration is needed in correlating the relationships of the strength of pavement structures based on FWD and BB.

The use of road marking paint for safety of road users currently increased rapidly and with the use of high quality of road marking paints led to the reduce of traffic accidents. Based on field observation showed that preliminary ageing of road marking paints occurred. Research results of road marking paints of several road links in Bandung conducted at the end of 2001 with observation over the year of 2002, abration was found for the manual application (by hand brushing) with the abration percentage reached 100% during one year after application, using marking machines (compressor), the wearing reached 80% when the surface was well prepared and the paint was well laid (with compressor), loss of adhesion can be reduced to 50% over one year. Based on on observation, high traffic is the main cause of loss of adhesion compared to environmental factor measured i.e the average temperature on the pavement surface still below the softening point of asphalt

The article presents the research result on the relationship between chemical properties and rheological properties of several asphalt samples as road pavement materials. The research was conducted in the following ways 1) chemical analysis to determine the content of asphalten and the parameters of malten composition as the comparison between the number of nitrogen fraction base plus acidafit I and Acidafit II plus paraffin before and after heating. 2) to determine rheological properties of asphalt, asphalt penetration, weight decrease (evaporation of light fraction) before and after heating, asphalt penetration ratio (ageing). Determination of asphalt malten composition parameters was done by solubility and precipitation method developed by Stenberg Rostler. The result showed that there is a relationship between malten composition parametr, asphalten content, penetration before and after heating. Asphalten content is indentical to asphalt penetration value (asphalt hardness), high content of asphalten, low asphalt penetration. Asphalt Weight decrease (fraction evaporation) does not parallel with the parameter of malten conposition value eventhough light fraction changed into densed fraction due to heating. In general, there is no significant relationship between the change of asphalt chemical properties as a result of heating and asphalt ageing. In Other words, the change of chemical properties indefinitely parallel with the change of rheological asphalt properties. Therefore, asphalt durability cannot be determined from malten composition value or asphalt chemical composition and cannot be used as a reference in the evaluation of road pavement failure. Further research is required to find out the relationship between asphalt chemical properties and mechanical properties of asphalt mixes so that the findings can be used to predict the durability of road pavements.

Indonesia has big sources of limestones which have not been used in asphalt mixes, therefore, their use for road pavement construction should be socialized. The goal of the research is to find out the propertes and comparison of limestone aggregates from two different locations namely Wonogiri and Tasikmalaya, West Java. The performance of Asphaltic concrete with AC–binder specification for limestone aggregates from Tasikmalaya was compared with Bina Marga II Specification for limestone aggregates from Wonogiri. The result showed that limestone aggregatesex Tasikmalaya have the optimum asphalt content of 6.55%, Marshall stability 52% higher, dynamic stability increased to 23% and stiffness modulus at the temperature of 24% higher than standard aggregates ex Sumedang. Limestone aggregates ex Wonogiri have the optimumasphalt content of 5%, Marshall stability 15% higher, dynamic stability increased to 8,7% and stiffness modulus at the temperature of 25°C increased to 43,4% compared to standard aggregates ex Banjaran. The research revealed that both aggregates performed better than standard aggregates. It means that limestone aggregates provide skid resistance to disintegration of road pavement.

There are many types of Hot Mix Asphalt mixture for wearing course, one of them is sand sheet. Sand is one of natural aggregate which is needed for sand sheet mixture, nevertheless the use of natural sand will affected environment, and also in some places this kind of material is difficult to find or its quality is not conform with the defined specification. In some places such as Timika (Papua), a sand sized material, which is a waste product of gold and copper mining process from PT Freeport, namely Tailing is abundant. Until recently, Tailing never been used in road construction. This paper will explain the effect of variation of tailing addition in sand sheet mixture. The use of Tailing as road material will reduce the effect of this waste to environment.

On street parking at this time can not be avoid yet, on the other hand the existence of parking will affect traffic performance, how far the trouble can be happened. With apparatus of analysis operational traffic performance can be determined using some performance variable like speed, volume, and capacities. Intention of this research is to look for relationship between speeds of vehicle with degree of saturation. This relationship can benefit to all planner in specifying location criterion traffic performance that happened can be estimated by configuration form of on street parking. However, a further research still need a continuation development, mainly concerning with road type and amount of samples. Especially the result of this research can produce an alternative approach for planning an on street parking.

One of the alternative technologies for landslide handling is a horizontal drainage. Development of this technology has been started since 1997 with full scale trial model of line perforation type and hole perforation type for several depth variations at the road Cikalong – Cariu Km 4+725 (Cariu) which constitute as an alternative track between Jakarta – Bandung. The objective of this handling was to reduce the water level of the land from slope of road and to identify the effectivity of the landslide handling. The problem of landslide was the road depression of 35 m. Analysis of the monitoring data showed that ground water surface has degraded for 0.005 m (at external field of slide area) and 0.105 m (at the slide area), pore water pressure has degraded for 0.2 mH2O on line 1 and 0.71 mH2O (at the slide area), water flowrate released on horizontal drainage outlet of hole perforation type was 0.011 to 2.42 L/day, higest than the line perforation type, land surface movement happened on the main and base slide was 0.1 to 1.1 cm. Monitoring result of landslide handling with this construction was quite effective to be applied to landslide problem on slope slide and road segment with ground water (water table) factor which uncontrolled on permeable soil. The type of perforation pipe which is more effective to be used is a hole type

The gap in capacity of the local government in managing the village roads is somehow filled by efforts of the community to develop and construct their own road. This is a strong indicator that community participation can conctribute directly in regional economy development in particular to improve accessibilty and mobility. However such efforts seem likely to be more output oriented than outcome based oriented. In addition, these are unlikely to be sustainable. A research funded by the Directorate General of Municipality and Rural Development (TPTP), Ministry of Settlement and Regional Infrastructure (MSRI) is designated to look at this matter and seeks for the best practice in managing partnership between community and govermment in road management. The study took 4 cases of village road management involving community participantion in District of Bandung, Bandung Municipality, District of Kuningan, and District of Ciamis, West Java. The qualitative assessment on these showed that the disorientations and sustainability issue are generated by the failure in integrating the public participation principles within the project cycle. The weaknesses in associated with planning, design, and evaluation is required significant improvment. To improve this situation, technical advisory form local government is suggested. In addition to this, the study has also suggested the use of standard references in assessing the performance of community participation of a road project. This would function as a guide in community based road management. Two papers regarding this subject would be published in two series of this journal. The first discusses the basic principles and process of community participation in road project, wile the next one would provide information of assessment results for the 4 study cases area in Bandung, Kuningan, and Ciamis
