Durability and Aging Characteristics of Sustainable Paving Mixture

Abstract

With the industrial revolution, many inventions have been introduced with many solid waste materials in return. This study investigates the potential recycling of waste plastic sheets, made from low-density polyethylene, as asphalt modifier in the paving mixture. The shredded plastic sheet was used in the asphalt mixture via the wet process. The dosage rate was set up to 9 % by weight of asphalt binder (0,3,6, and 9)%. The experimental program was designed to assess the mechanical properties (Marshall stability and flow, and volumetric properties), durability, and short-term aging of asphalt mixtures, in addition to economical assessment. The test results revealed the applicability of using this solid waste material in paving construction as a surface layer, since its usage enhances the pavement performance by increasing stability, index of retained strength, and volumetric characteristics before and after aging as well as saving in cost. The best enhancement can be achieved with 6% of recycled low-density polyethylene.

Discrimination of Plastic Waste using Laser-induced Breakdown Spectroscopy-principal Component Analysis: Highlighting Molecular LIBS

“…Abdulmadjid) considered to play a key role in saving the world from plastic waste disaster [3,4]. One of the examples of the recycled plastic use is in asphalt mixture [5,6], which requires certain type of plastics to achieve optimum durability. Prior to recycling process, an important step needs carried out is classifying the plastic waste based on its type [3].…”

Sustainable Use of Polypropylene Fibers as a Cement Mortar Reinforcement

“…On the other side, these developments in building materials and industry resulted in accumulation of waste materials. These synthetic materials are nonbiodegradable [20] that means it will accumulate over the land and cause land and marine pollution. Fortunately, these waste materials can be recycled and used as concrete fibers.…”
