It is very important to carry out an uninterrupted, sustainable, and environmentally compatible policy in infrastructure applications. Infrastructure elements are available in many areas such as water, electricity, gas, sewage, transportation, etc., thus special action plans are required for their maintenance and repair. For this reason, reducing the external effects (natural disasters or human effects) that will cause malfunctions with protective layers will be an appropriate solution that contributes to time and economy. Today, artificial ground reinforcement elements are available. However, this special issue is very interesting in terms of supporting and examining studies on protective and strengthening elements obtained by the evaluation of natural wastes that will create an alternative to artificial, synthetic, and petroleum-derived products. Thus, studies to recycle waste materials will be encouraged, and the use of more economical and recyclable materials to strengthen infrastructure soil will create more attractive opportunities in today's conditions. As a result of the existence of natural reinforcement structures that serve as reinforcement on the soils, the necessity of changing the infrastructure routes will be eliminated by correctly designed projects. Instead of escaping weak soil, the problem will be solved on the existing route in a fast, reliable and inexpensive way. Static or dynamic loading to simulate natural disasters can also be the subject of studies. This special issue offers researchers an opportunity to publish their studies in theoretical, numerical and experimental about “Strengthening infrastructure and soil with protective layer applications based on sustainable natural waste materials”. You are invited to submit your manuscripts to this special issue of the Journal of Civil, Construction and Environmental Engineering (JCCEE).
