The article deals with the problem of creating vibration damping polymeric materials with high damping properties in a wide temperature range. The purpose of the article is to study physical-mechanical properties of composites based on ethylene-vinyl acetate by adding various modifiers in the form of resins. The main method to investigate this problem is the method of dynamic mechanical analysis, which makes possible to obtain viscoelastic properties of polymeric materials under the influence of an oscillating load at various temperatures and oscillation frequencies. Due to the established experimental dependencies, the authors have determined the type of resin, which improves the damping properties and increases the stiffness of the composites based on ethylene-vinyl acetate. Moreover, the authors have defined the limit of working capacity of composites with resins at negative temperatures.

Asphalt Modification

One of the polymer materials that can be a mixture of asphalt is Ethylene Vinyl Acetate, which is a material that is widely used in making toys and making footwear. This large amount of toys and footwear production waste has only become rubbish and has not been utilized optimally. Ethylene Vinyl Acetate polymers themselves belong to elastomeric polymers which have flexible properties such as rubber, smooth, flexible, resistant to low temperatures, are not easily cracked and are resistant to water. The use of polymer material as a mixture of asphalt has been widely carried out considering that asphalt modification with polymeric materials is known from several tests showing that it has better resistance to deformation and overcoming cracks, so that road construction can be produced more durable and can reduce maintenance and repair costs Street. In this study the use of Ethylene Vinyl Acetate waste on asphalt mixes has a pretty good effect, this is seen from the results of marshall tests that can meet the requirements.

Different series of high density Polyethylene/Ethylene Vinyl Acetate (HDPE/EVA) blends were prepared via melt blending in a corotating intermeshing twin screw extruder. The effects of VA percentage and EVA loading ratio on the thermal, rheological viscoelastic, mechanical, and fracture toughness of the blends were analyzed. The results showed that the addition of EVA to HDPE reduces the thermal, elastic, and viscoelastic properties of the blends. The microscopic examination of the fracture surface confirmed the ductile fracture of HDPE/EVA blends for all blend ratios and VA percentages. Increasing the EVA ratio and VA content caused a significant reduction in the blend crystallinity but had no significant effect on melting temperature. The complex viscosity increased with increasing the percentage of EVA due to the restriction of molecular mobility and reduction of free volume, induced by the addition of EVA. The storage modulus decreased with increasing the EVA ratio and temperature, while it increased with increasing the frequency. Young’s modulus, yield strength, and fracture strain decreased with increasing the EVA ratio. Similarly, the fracture toughness decreased proportional to the EVA percentage. Finally the results indicated that the VA content has significant effects on the mechanical, thermal, and dynamic properties of HDPE/EVA blends.
