Trylinka (Polish: [trɨˈliŋka] ; pl. trylinki), also known as shashka Trylins'koho (Ukrainian: шашка Трилінського, lit.'Tryliński's paving block'),[1] is a concrete block, typically shaped as a regular hexagon or occasionally a tetragon, with stone fragments embedded in its upper layer. The types of stone used for these embedments, such as basalt and porphyry, vary depending on local availability. Inexpensive, durable and relatively simple to build, trylinki were mass-produced and used on a large scale in the construction of roads in interwar Poland, covering an estimated 1 million square metres (11×10^6 sq ft) of surface area between 1933 and 1938.[2][3] Some of these roads are now located in present-day Belarus and Ukraine.

Trylinka is named after its inventor, Władysław Tryliński, a transportation engineer credited with the engineering design of the Maurzyce Bridge, a project he shared with construction engineer Stefan Bryła.[4] Whilst overseeing the production of aggregates and paving slabs at the Miękini porphyry quarry [pl], Tryliński observed that the manufacturing process generated large amounts of fragmented stone waste, leading to his idea of recycling these fragments as embedments in trylinki.[5]
