In this paper, firstly, based on asphalt pavement central layer, the comparison with the foreign related gradation of asphalt mixtures, one typical kinds of gradations are decided; Secondly, the asphalt aggregate ratio is predicted based on professor Lin’s Theory , and five asphalt aggregate ratio are selected. Finally, the road performance of asphalt mixture is experimented, and the road performance of five asphalt aggregate ratio is analyzed. As a result, we can predict the range of the optimum asphalt aggregate ratio based on the road performance.

Along with the increasing number of the population of Sidoarjo, this has an i mpact on traffic volume, it occurs on the road of Gedangan roads to Buduran, therefore carried out the transfer of road access to the East Ring Road with specialized for heavy vehicles, due to the transfer of the road, it is necessary to perform the analysis of the East circumference road performance. The research aims to determine the magnitude of the influence of heavy vehicle volumes on the road performance of the East Ring road. The performance Of the east circumference traffic by counting the Level Of Service (LOS) and calculating the volume Of the vehicle compared to the road capacity (degree Of saturation). Traffic volume Data surveyed for 2 days (6 and 10 August 2020), for 6 hours per day at 06.00 – 08.00, 12.00 – 14.00, and 16.00 – 18.00. The analysis of road performance is using the Manual road Capacity (MKJI) method with a degree of saturation (DS) as the main indicator of road performance. The results of the analysis showed the performance of the road on the condition of the excitation point 1 the value of saturation of 0.61 and in point 2 of the value of saturation 0.97 and the result of service level of roadway 1 is C (steady current speed and motion-controlled vehicles) and in point 2 is E (current unstable speed sometimes stalled close request of capacity).

<p align="center"><strong><em>Abstract</em></strong></p><p>Highway is a land transportation infrastructure that forms a transportation network to connect an area to other regions, so that the wheels of the economy and development can rotate well. This research was based on the road age of the third year of the road Krueng Geukueh - Beureughang, so the researchers wanted to know what factors were the causes of performance degradation on the road and the relationship between the decline in road performance on the material used. In this study includes 3 stages, namely, Core drill, Marshall Test testing and testing of Test Extracts that have been achieved using 8 (Eight) samples. So it can be concluded that there has been a decrease in asphalt levels on the road resulting in damage and decreased performance on the road. Coupled with increased charges within 3 (three) years, therefore repairs to the road are needed. From this research, it is expected to be able to provide input to improve the quality of the material and the layer of road surface pavement.</p><p> </p><strong><em>Keywords :   Decreasing Road Performance, Core Drill,  Marshall Test, Test Extract,  Asphalt Level.</em></strong>

Warm-mixed reclaimed asphalt pavement (RAP) technology has been widely studied worldwide as a recycled environmental method to reuse waste materials. However, the aggregate skeleton structure of the warm-mixed reclaimed asphalt mixture is not stable because of the existence of the recycled materials. Warm-mixed recycled semi-flexible pavement material can solve the defects of the above materials. In this study, five different types of open-graded asphalt mixtures containing different contents of RAP were designed, and relevant laboratory tests were conducted to assess the road performance of the warm-mixed recycled semi-flexible pavement material. The test results indicated that the road performance of warm-mixed reclaimed semi-flexible pavement materials has good resistance to rut deformation ability. Furthermore, the materials also had good water stability and fatigue performance. The grey correlation analysis shows that the asphalt binder content has the most significant correlation with the high-temperature stability, and the correlation between RAP content and the fatigue performance was the greatest. Furthermore, the curing age has the most remarkable with the low-temperature crack resistance of the warm-mixed reclaimed semi-flexible material.

Abstract Road drainage function as important part that can control a large rainfall that caused puddles that often disturb the comfort of all community activities on the road. Condition of the drainage channel on the road Kebon Pala area, East Jakarta are not qualified due to mistake planning and lack of maintenance. Hence, it is necessary to evaluate the capacity of drainage channel on Road Perindustrian. The purpose of this study is to find the maximum amount of water flow that can be accommodated by drainage channels. Rain intensity was calculated using the Mononobe method, as well as the flow rate is calculated using the Rational method. The existing capacity of drainage dimensions are measured directly in the the field using Manning method for calculating flow velocity. The results obtain Q2yrs = 1.27mm/s, Q5yrs = 1.67mm/s, Q10yrs = 1.84mm/s, while Q channel 0.24mm/s. Thus, it can be concluded that capacity of road drainage channel is lower than Q rain that can not accommodate the existing rain flow.
