The aim of this research was the investigation of the properties of clay brick masonry arch bridge materials with a purpose to find the best methods for reconstruction and renovation of the structure. The restoration, reconstruction and upgrading of historical heritage bridges require the careful investigation of materials and causes of damages. In many cases, the use of incorrect composition of joint mortar and clayed brick could lead until an unfavorable result. It is important to ensure the natural water migration in historic masonry could not be interrupted after restoration or reconstruction measures. As an example had been analyzed the results of investigations and upgrading of a historical clayed brick masonry bridge over Venta River in Kuldiga town in Latvia (figure 1). During the long lifetime and pro-active maintenance polity, a bridge had a lot of damages that could influence the further service life. For geometrical data collection was used laser scanning method that ensures enough accurate data for reconstruction design and information for architectural investigation. Three-dimensional scanning of heritage structure by 3D laser scanners allow the further transformation of information into the surface mesh model. Paper presents results of investigation and design of restoration and reconstruction works.
