Almost 40% of road in Indonesia are damaged. To obtain the maximum result of road improvement, the surface course (asphalt pavement) of the damaged road should be removed. Considering the number of quarries of road pavement materials are limited in the future and the costs are getting more expensive, it is important to do research on recycling asphalt pavement material as road base material. The objective of this research is to examine the use of asphalt pavement removal as road base material. Laboratory test was conducted to investigate the properties of the removal road asphalt pavement and then compared with specification of road base material Bina Marga. The tests include abrasion test, particles size distribution, density and California Bearing Ratio (CBR). Research was initiated by investigating the removalÂ ofÂ asphalt Â pavement maerial, followed by removal of asphalt pavement material + new aggregate, and the addition of 0.5%, 1%, 1.5%, 2% and 2.5% portland cement to the mixture of removal of asphalt pavement material and new aggregate. The result shows that adding 0.5% and 2.5% portland cement to the aggregate mixture can improve the CBR of aggregate mixture by 36% and 94%, which means the mixture of aggregate can be used as sub base and base material of road.

This paper reports the results of an investigation of the durability of the AC-WC mixture using latex based on the SNI 6753:2015 test method. This method uses a test object with a low density (7% air void), while another method, namely Bina Marga (BM) 2018 which is more often applied in the field, uses a normal density test object (air void 4%). The product of these two different methods needs to be evaluated. On the other hand, the performance of latex on the durability of the AC-WC mixture at low density also needs to be studied. The main objective of the research is to study the durability of the AC-WC mixture using latex based on the SNI test method, compare it with the BM method, and at the same time evaluate these two test methods. The research method used is to conduct durability tests in the laboratory on test objects with low and normal densities. Two types of specimens were prepared, namely without and with latex, both were tested in conditions without and with immersion. The properties of the test object were evaluated using Indirect Tensile Strength (ITS). The test results were studied and compared, including to evaluate the two test methods. The results of the study concluded that the AC-WC mixture at low density (7% air void) had high durability with an IKS value above 90%. The value of the durability of the mixture is higher when using latex and at normal density (4% air void). The SNI 6753:2015 test method that uses 7% air void specimens is more recommended for evaluating the durability of asphalt mixtures.

On the inside of the dam, there is a seamless instrumentation. V-Notch is one of thestandard dam safety instruments used to measure water dam seepage discharge. Theporous soil and high permeability around the V-Notch cause water seepage to notbe directed properly to the V-Notch. If it is not directed properly then the erosion ofthe reed or piping cannot be detected. So we need a construction design of thebarrier wall for collecting water seepage, namely the wall diaphragm wall. Thepurpose of this research is to analyze the material, evaluate the performance, andcompare the diaphragm wall. The method used is falling head test, monitoringobservation well (OW), direct observation method when working. The results of thedownstream wall diaphragm material permeability test using the fall head test showthat the largest permeability coefficient value is 1.3 x 10-5cm/sec. where this valuehas reached a low coefficient of permeability. Results Downstream wall diaphragmperformance based on groundwater level at OW.8 < from OW.7. Downstreamdiaphragm wall or water seepage collection barrier can be said to work well. Fromthe analysis method, the diaphragm wall is easier to work than using the Clay heapmethod. This is proven because the diaphragm wall method can be carried out in therainy season and dry season. From the time calculation analysis, it is known that itis faster to use the diaphragm method with an estimated working time of 4 months 2days using 1 tool.

One of the infrastructures that society absolutely needs is roads. With the existence of roads, land transportation activities are carried out so that economic and social mobility runs normally. Concrete is one of the materials commonly used for road pavements, where this material technology has many advantages such as being able to withstand heavy vehicle loads and lower maintenance costs. To produce quality concrete roads, the role of the manager who leads the concrete road construction project is very decisive. To produce a quality concrete road, a manager must be able to determine indicators that influence its success, so that construction activities run effectively and efficiently. This study aims to identify Key Performance Indicators (KPIs) that can be used as a measure of success in concrete road construction projects based on the perspective of construction service providers. The analytical method used in this study is the Relative Importance Index to determine performance indicators that can be used as KPIs based on their relationship to success in concrete road construction projects. The results of the analysis show that the performance indicators that can affect the success of a concrete road construction project based on the perspective of a construction service provider are cost, quality, time, productivity, and environment, each of which has a weight of 21.41%, 19.44%, 19.05%, 15.65%, 12, 86% and 11.59%.
