It road construction services help customers to understand the behavior of road materials with expected loads and deterioration mechanisms. It has the experience and expertise to test and assess the performance and durability of road materials and products.
Assessment and improvement of asphalt properties Determination of asphalt component quality and suitability (bitumen, aggregates also secondary) Development of new road products, including roll pave and road materials Assessment of damage to (overheated) asphalt Laboratory testing of bitumen, including composition (PAH and rheology/viscosity) Calculations of the CO2 footprints of semi-heated asphalts Assessment/testing of expansion joints Determination of the maintenance condition of existing roads, drawing up subsequent maintenance/repair plans Service life predictions Controls of road mixture designs and auditing/inspection of road product application.
