Abstract

The characteristics of semi-flexible pavement (SFP) are strongly influenced by the proportion of cement mortar content filling the voids in the mixture. SFP behavior due to repeated traffic loads causes the pavement structure to experience stress and strain around the wheel axis, resulting in a rapid decline in performance with cracks and permanent defects. Evaluation of the properties of the mixture on the stress-strain parameters of the influence of additives and substitution of many SFP mixture-forming materials has been carried out. The purpose of this study was to determine the stress-strain models of SFP with the effect of waste tire rubber (WTR) additives in asphalt and Aceh natural zeolite substitution in cement mortar under uniaxial compressive load. The porous asphalt mixture is designed in accordance with the optimum asphalt content and open graded aggregate based on the specifications of Bina Marga Regulation 2010 and Australian Asphalt Pavement (AAPA) 2004. The composition of zeolite in SFP mixture can affect the stress behavior, where zeolite can inprove quality of the mortar cement so that it can slow down the development of the SFP mixture flatness and the maximum stress obtained is 17 MPa at 5% zeolite composition. The bilinear model of stress-strains was proposed the results show a good agreement with experimental results.

Abstract

Concrete is a building material that consists of a mixture of aggregate and paste. Normal concrete has a unit weight of 2200 kg/m3 to 2500 kg/m3. In addition to normal concrete, lightweight concrete is also known which has a unit weight of less than 1900 kg/m3. The research was conducted to produce lightweight concrete by using aggregate from polyethylene terephthalate (PET) plastic waste as a substitute for coarse aggregate. This study used 40 cylindrical samples of 150 mm x 300 mm with variations in the use of PET aggregates of 25%, 50%, and 100% of the volume of coarse aggregate. The results show that the use of PET aggregates produces concrete with a decrease in compressive strength of 26%–39% and a decrease in water absorption of 2%–32% from normal concrete. Ultrasonic Pulse Velocity (UPV) testing showed that the concrete with PET aggregates had a lower wave propagation velocity compared to normal concrete. Moreover, Schmidt hammer and splitting tensile test showed that concrete with PET aggregates had lower rebound number and split tensile strength compared to normal concrete. PET substitution percentages of 25% and 50% resulted in unit weights of 2218 kg/m3 and 2102 kg/m3, respectively, which rule out the use of lightweight concrete. However, 100% PET substitution has a unit weight of 1855 kg/m3 with a compressive strength of 14.16 MPa, which can be categorized as moderate structural lightweight aggregate concrete.

Abstract

Interprovincial movement activities from the city of Lhokseumawe to the city of Medan is a busy travel route because land routes connect many cities. Minibusses and buses serve transportation needs across these cities. Travelers tend to choose minibusses because of their convenience, fast travel time, and the excellent level of comfort provided. The bus mode also offers smooth and comfortable travel, making it a popular choice among travelers on the Lhokseumawe to Medan route. This research aims to determine the characteristics and percentage of transportation mode choices by travelers. The approach used is the analytical hierarchy process method. The results of the analysis showed that the percentage of travelers interested in choosing a particular mode resulted in 42% of passengers choosing the Hiace Minibus, 24% choosing the Sempati Star Bus, 20% choosing the Putra Pelangi Bus, and 14% choosing the Kurnia Bus. The criteria that influence the choice of transportation mode are convenience with a percentage of 22%, time with a percentage of 19%, comfort with a percentage of 16%, cost with a percentage of 15%, headway and safety with a percentage of 14%.
