Influence Of Temperature

Asphalt concrete exposed to cracking, flaking, chipping, formation of ruts, waves and troughs. Introduction into a mixture of small size (discrete) components allows achieving their uniform distribution (dispersion) in the mixture and obtain a "composite" material having a high physical and mechanical properties in the finished structural member. Studied technology of composite dispersion-reinforced with basalt fibers asphalt mixtures, taking into account the influence of temperature.

In Lithuania dolomite is the third most excavated by the amount mineral resource, which is mostly used in subbase layer and hot asphalt mixtures for asphalt binder and base courses. Although, for asphalt wearing layer are often used granite aggregates, but this magmatic rock is imported from foreign countries. In one of the quarries of JSC “Dolomitas” higher quality dolomite is produced, which has similar mechanical properties to granite. To determine changes in mechanical properties of the different type of aggregates while using in the road, high-quality dolomite and two types of granite were chosen for laboratory testing. In this study, for evaluation of physical and mechanical properties of aggregates by laboratory tests for determining resistance to freezing-thawing, resistance to fragmentation, and polished stone value were carried out. Also, according to the results of laboratory testing, high-quality dolomite aggregate showed equal performance comparing to granite aggregates.

Article Usage

Asphalt is used in road pavements as the binder of aggregates in a great extent all around the world. Asphalt Modifiers have used in pavement engineering in order to enhance the physical and mechanical properties of asphalt mixtures. One of the most important of them is Polypropylene Fiber that causes increasing stability in the mixture. In this article usage of this fiber in civil engineering and especially in asphalt mixtures is investigated; Mixing methods of fiber with aggregates and bitumen are dry, wet and complex are investigated and the most appropriate method because of homogenous mixing and better result is introduced.

Compaction Performance

The compaction can directly affect the performance of asphalt pavement, while the mixing temperature, the molding temperature, the temperature of aggregates and the rolling times can all affect the compaction performance. The L9(34) orthogonal tests and indoor tests were used to analyze the influence of the main factors on the examination indicators. The results show that molding temperature have a significant effect on the physical and mechanical properties of SMA13 asphalt mixtures when the confidence level α is 0.10. Finally, quantitative analysis is performed to study the optimal compaction technology of molding temperature and rolling times.

Timber Acacia mangium (Acacia mangium, Willd) for Furniture. The study aims to determine the mechanical and physical properties and the decorative value (color and fiber) wood of acacia mangium with using finishing materials. This type of finishing material used is ultran lasur natural dof ,ultran lasur classic teak, aqua politur clear dof, aqua politur akasia dan aqua politur cherry. After finishing the wood is stored for 3 months. Test parameters were observed, namely, physical and mechanical properties of wood, adhesion of finishing materials, color and appearance of the fiber, and timber dimensions expansion. The results showed that the mechanical physical properties of acacia wood qualified SNI. 01-0608-89 about the physical and mechanical properties of wood for furniture, air dry the moisture content from 13.78 to 14.89%, flexural strength from 509.25 to 680.50 kg/cm2, and compressive strength parallel to fiber 342.1 - 412.9 kg/cm2. Finishing the treatment process using five types of finishing materials can increase the decorative value (color and fiber) wood. Before finishing the process of acacia mangium wood has the appearance of colors and fibers and less attractive (scale scores 2-3), after finishing acacia wood fibers have the appearance of colors and interesting and very interesting (scale 4-5).Keywords: mangium wood, mechanical properties, decorative value, finishing, furniture.

An investigation on the properties of Tenun Pahang fabric performances using alternative yarns was conducted. The studies were made in order to evaluate whether the Tenun Pahang fabric could be produced economically and at the same time maintain the fabric quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project, two alternative yarns were used which were bamboo and modal, which were a little lower in cost compared to silk. These yarns were woven with two variations, one with the yarns as weft only while maintaining the silk warp and the other with both warp and weft using the alternative yarns. Four (4) physical testings and three (3) mechanical testings conducted on the fabric samples. The fabric samples were evaluated including weight, thickness, thread density, crease recovery angle, stiffness and drapability. The results show that modal/silk and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they have the potential to replace 100% silk Tenun Pahang.
