Asphalt is a common material that is used extensively for roadways. Furthermore, bituminous mixes have been used in railways, both as asphalt and as mortar. Different agencies and research institutes have investigated and suggested various applications. These studies indicate the benefits of bituminous material under railways, such as improving a substructure’s stiffness and bearing capacity; enhancing its dynamic characteristics and response, especially under high-speed train loads; waterproofing the subgrade; protecting the top layers against fine contamination. These potential applications can improve the overall track structure performance and lead to minimizing settlement under heavy loads. They can also guarantee an appropriate response under high-speed loads, especially in comparison to a rigid slab track. This review paper documents the literature related to the utilization of asphalt and bituminous mixes in railway tracks. This paper presents a critical review of the research in the application of asphalt and bituminous mixes in railway tracks. Additionally, this paper reviews the design and construction recommendations and procedures for asphalt and bituminous mixes in railway tracks as practiced in different countries. This paper also provides case studies of projects where asphalt and bituminous mixes have been utilized in railway tracks. It is anticipated that this review paper will facilitate (1) the exchange of ideas and innovations in the area of the design and construction of railway tracks and (2) the development of unified standards for the design and construction of railway tracks with asphalt and bituminous mixtures.

Moving Train

July 2007. Hundreds of Central American migrants were camped along the railway tracks in Arriaga, Chiapas waiting to for the freight train to leave. Some were eating, perhaps their last food for days, others had bottles of water tied across their shoulders, some attempted to rest under the train cars to escape the hot sun. One young man brushed his teeth under the trees, using the water he carried in a recycled coca-cola bottle, to prepare himself for the journey ahead. Arriaga, a town of 25,000 people, is split in half by the train tracks. The town's tiny plaza, with a small playground, fondas (eateries), and a railway museum, sits on one side of the tracks. The town's church and market lie on the other. These Central American migrants in Arriaga, some 150 miles from Mexico's southern border with Guatemala, were eager to jump the freight train to continue their journey north to the United States. The train had not left Arriaga for a full week and many were desperate as they felt trapped. Their preparations underscored the dangers and harshness of the trip. They would have to hold on to the train for hours and days at a time, riding on ladders and the roofs of tank cars. Those who fall asleep and lose their grip risk death or severe injury, such as dismemberment.
