“…The increase of this cavity was caused by the length of the fiber, also the damage and the changes in length caused by the compaction load; there was a reduction in length and the increase in the percentage of fiber. Therefore, the percentage and the length of fibers that exceed the effective limits usage have less profit effect to the characteristics of the resulting mixture 6 [36]. Figure 9 shows the relationship of elastic modulus value with the ratio of fiber length.…”

“…The existence of fibers in the mixture caused greater tensile pressure with Asphalt Pavement, JTG / F40-2004 3 . To ensure a good distribution of the mixture, the fiber must have an optimal length 6 . The structure of the porous network in one bond attached to the fiber surface, which significantly increased the cohesive strength between the fibers and the mixture, and limited the slip of the fibers in the mixture 6 .…”

“…The fiber in the asphalt concrete mixture is intended to improve the properties of the mixture, for instance by increasing the strength of the material and the characteristic of fatigue, and increasing the ductility 3,4 . Furthermore, it is known that fiber may contribute to avoid crack formation and propagation 5, 6 , increasing the cohesive strength and tensile mixture, provide physical changes to the asphalt mixture 7 , the absorption rate and surface area depending on fiber type 8 . Basically, fiber contributes to the change of the viscoelasticity in the modified asphalt, improves the dynamic modulus 5 , temperature sensitivity 9 , creep resistance, rutting resistance 10 , and reduces the reflective cracking of asphalt on the asphalt mixture and structure.…”

:The objective of this research was to analyze the indirect tensile strength of the asphalt concrete mixture with fiber reinforcement that was immersed on the sea water. The method of research was an experimental testing on the mechanical properties of fibers and indirect tensile strength of the mixture with a variation of length were 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm and the variation of fiber content for each composition was respectively 0.2%, 0.4%, 0.6%, 0.8%, 1.0% and 1.2% with the optimum diameter of fiber was 0.3 mm. Each composition of the mixture was tested for each variation of length and fiber content with the optimum asphalt content of 5.9%. The seawater-immersed fibers with the immersion duration of 3 weeks gave high tensile strength and strain. The 0.3 mm diameter fibers with 3 weeks immersion had a maximum stress = 130.45 N / mm 2 , and maximum strain of 14.24% while those in control had a maximum stress = 13.71 N / mm2 and maximum strain of 13.89%. While the indirect tensile strength (ITS) test results on five variations of length and percentage of fibers in the asphalt concrete mixture, the 0.6% fiber content composition provided ITS value of a maximum stress = 26795.84 kPa and maximum strain in the fiber length of 8 mm was 0.01486 and an elastic modulus was 2318478.25 kPa. The composition yield a Poisson ratio = 0.44. The Poisson number is an indicator of the ductility of a mixture.

Due to high levels of volatility in both the agricultural and the forestry commodity markets, specifically, of timber and agricultural crops, it is important to identify the risks associated with the stability of supplies necessary for the production of composite materials in the Czech Republic. This study aims to accurately estimate the availability of selected raw materials that contain lignocellulose over the next 20 years. In addition, their suitability for the production of composite materials is assessed based on their physical properties. Furthermore, in the event of scarcity involving timber in the European Union, recycled wood and post-harvest residues could replace conventional raw materials in wood-based composites such as particleboards and chipboards. The viable potential of Czech forests is predicted to be between 740 and 750 million cubic meters of timber. For agricultural crops, it is estimated at 0.9 million hectares of wheat and 0.5 million hectares of canola under the current EU biofuel policy and at 0.4 million hectares if this policy is removed. According to moisture and fibre analyses carried out in our study, the most suitable candidate for wood-based composites production is soft wood.
