damage of the fastening system components and the concrete rail seat. Additionally, reducing life cycle costs of concrete sleepers and fastening systems through improvements to the rail seat is of extreme importance to the railway industry to ensure the continued acceptance of concrete sleepers as a viable means of rail restraint.

The widen of sleepers in the rail seats is an innovative idea proposed by Hayano [53,54] to increase the interlocking of the crib ballast with sleepers. Based on experiments, the lateral resistance of 40 mm-winged sleepers was 67% higher than the typical type.To assess the performance of winged sleepers, a series of STPT tests were conducted on two types of …

Concrete crushers are powerful equipment to reduce concrete into smaller, more manageable pieces. Crusher buckets, for example, attachments to excavators and loaders, are used for crushing concrete on site. These units work by applying a force to the material more significant than its compressive strength, breaking it into smaller pieces.

However, they have gradually replaced timber and steel sleepers [7]. On the other hand, concrete sleepers have a longer lifespan than their wooden sleepers counterparts, reaching 50 years [8]. Concrete sleepers are an excellent choice for a variety of reasons. The heavyweight for the concrete sleeper adds to the track's strength and stability.

The following conclusions are arrived at. 1. Presence of crumb rubber in concrete has increased the resistance to crack initiation under impact load by 80–110%. 2. Impact load at failure was 50% high for concrete with crumb rubber. This is due to the energy absorption capacity of the crumb rubber. 3.
