The Innovation of Natural Rubber Applied with Concrete Road Barriers in Thailand

Abstract:

The Development of Natural Rubber for Traffic Devices in Thailand has been researched in several years. The enormous budgets have also been invested for the increasing of rubber prices. One of Traffic Devices is the application of natural rubber sheets for the protection of motorists - driving motorcycles as crashed through concrete barriers. The number of road side accidents on rural roads in Thailand is about 3 fatality per 10 kilometers. Therefore, the 11.20 MTB per a Fatality of accident cost is evaluated to be 3,360 TB per km. This leads to the mitigation methods to remedy a symptom’s motorist from severity to moderate and mild respectively. The solution is to find the best practice of road barrier which is applied with natural rubber latex glued with concrete barrier. In addition, the composite materials will be calculated of the modulus of elasticity and properties such as, strength and durability. The simulation of crashes, finite element of materials, LRFD and Concrete Technology methods will be taken into consideration. The testing of material in Thailand will be firstly applied for these, for example the road crash testing under the standard of NCHRP – TL3 (100 kph) will be taken into account.
