Abstract

The segmented road of Bireuen-Takengon has often damaged in apart of its pavement structure due to the area of flexible pavement structure taken place upon an expansive soil that leads to depreciation caused by the influence of changes in the water level. The aim of this research method was to analyze the characteristics of the base soil underlying the pavement and to analyze the flexible pavement structure in the widening of the road. The observed area was Sta.70+175 s/d Sta.74+925 which taken place in Bener Meriah regency, sub-district of Timang Gajah. The results of USCS clarification show that the road of basal soil is included in the MH and OH with a PI value of 25.42%, LL 64.25% with a potential level of development and activity belonging to the medium-high category and also having mineral types of Illite. From the analysis of KENPAVE software, the design of flexible pavement structures is based on data planning that has a maximum stress and deflection value, on the base soil, of 0.1814 kg/cm2 and 0.0585 cm respectively. Moreover, based on Job mix data the maximum value of stress and deflection is 0.2444 kg/cm2 and 0.0585 cm respectively in which both of two stress and deflections are within the allowable limit; which both of two stress and deflections are within the allowable limit; 7.8 kg/cm2 and 2.5 cm. The evaluation results of both data are feasible to be used as an improved design on the pavement as the pressure generated by the weight of the road pavement structure is 1.949 kg/cm2, while the swell pressure that occurs on subgrade is 1.805 kg/cm2. Hence, The flexible pavement structure on the road segment is still able to reduce the swell potential on expansive soil.

Abstract

This research is located in Takengon - Uwak City boundary section. The benefit of this research is to figure out the proper type of road construction for investment based on financial feasibility with respect to Vehicle Operational Cost (VOC), Benefit Cost Ratio (BCR), Net Present Value (NPV), and Internal Rate of Return (IRR). The data used in this study was secondary data obtained from related institutions. The research method used in this research was economic indicators with two scenarios, that is; 1. Road improvement with no handling/ existing (Do Nothing), and 2. Road improvement. From the calculation results, it was obtained the price of construction and maintenance for each shoulder of the road construction, that is, the shoulder using Material Class B was IDR 5.493.388.958, the material class B shoulder with Geocel IDR. 4.946.201.289, and road construction using concrete IDR. 6.162.438.275. The saving of VOC produced was IDR. 23,006,00. The results of the economic analysis performed for the three types of construction with the Net Present Value (NVP) method resulted in Road Construction by Shoulder Using Materials Class B and Geocell is the best alternative to make an investment because it produces the largest NPV Value, that is, NPV=IDR 1,808,869,588,00. The highest BCR value is BCR = 1.49, with IRR value = 14.855%
