Abstract
Pavement surface characteristics are important since pavement surface relates directly to the safety, and comfort riding. This research aims to establish the impact of crumb rubber used on the flexible pavement by dry method. Rubber crumb is rubber waste which is processed through mechanical grinding or tire milling into small splinters. Indonesia is a country with a tropical climate that is different from Libya which has a hot climate. This difference influences road construction and repair in both countries. In Indonesia for example, the pavement surface requires a lot of petroleum asphalt as a binder. The damage is usually caused by high temperatures and rainfall. In Indonesia, petroleum asphalt is used as a pavement mixture. Although it meets the requirements of the specification, it often shows a decrease in service behavior due to rutting, fracture, and other forms of damage. The problems in this study are about the composition of crumb rubber side properties to have the high durability of flexible pavement with high temperatures. Since there are several of crumb rubber which come from many types of tires waste, these different types may have different impacts. Each type may have differences in improved high durability that can predict the permanent deformation with high temperature; moreover, it can affect its strength and fatigue life of a pavement. The objective of this research is to know the composition of the character of various crumb rubber come from sources of tire wastes and to have high durability of flexible pavement with different percentages of crumb rubber. This crumb rubber was collected from sources of vehicles (car, bike, motorcycle, truck). The experiment was done respectively through several phases as follows: preparation, quality examination of materials such as aggregate and asphalt, mixed-planning, and specimen testing implementation with Marshall Test. Properties of crumb rubber-like type stability and flow of durability can affect the different stability and flexibility of pavement. The data collected from the laboratory experiments were presented in different forms like tables, charts, diagrams, etc. The results from the crumb rubber asphalt mixture show that there is an increase in the amount of crumb rubber in a mixture of hot mix concrete asphalt. This mixture can increase the Marshall stability by 2.5 % % crumb rubber higher than the other mixtures with crumb rubber. The Indirect Tensile Strength properties (ITS) has a better low-temperature cold region with 2.5 % % crumb rubber. At certain stress levels, the samples with higher crumb rubber content failed faster than samples with less crumb rubber content in the condition of fatigue, stiffness, and permeability.
